INSTRUCTIONS

Congratulations on choosing a pair of “Aaron" loudspeakers. We at Aaron have gone to the upmost

trouble to ensure your continuing satisfaction for many years to come. Every individual speaker must

meet our exacting specifications with regards to performance and craftsmanship before it is allowed to

leave our factory.

The single biggest bone of contention that customers have with speaker manufacturers is

caused when a speaker is damaged by too much power input or by amplifier distortion. This is not

covered by warranty as it is deemed to be customer abuse, often the customer feels this problem

should not arise. So in an effort to further improve our relationship with you, (our valued

customer), there is something we will try to help you understand in an effort to circumvent this

potential problem.

As a manufacturer it is impossible to protect or prevent you the consumer from damaging the

speaker when one of the two following things happen:

1: Using an amplifier that has too much output for the speakers capacity.

2: Causing the amplifier to distort by turning up the volume too high.

The first problem is easy to avoid. When you purchase an amplifier you must take note of its`

power output. This will tell you the minimum size speaker to purchase. For instance if you

purchase a 100W speaker then the amplifier must be rated at 100W or less. By the way, it is

perfectly alright to use a 400W speaker with a 10W amplifier there is no limit in that direction but as

a general rule an amplifier closer to the rating of the speaker will sound a little better. If the speaker

is very efficient the improvement will be less obvious.

The second problem is far harder to understand and avoid. You see, even if the amplifier power

is smaller than the speaker it is still possible to damage the speaker. This is caused by what is

known as distortion. An amplifier distorts when the volume control is turned up too high forcing the

amplifier past its rated power output. So an amplifier rated at 100W can be forced to put out 120W.

But 20W of that power is distortion and this is what damages your speaker. The hard part is to

know when your amplifier has passed its limit and is distorting. The position of your volume control

will not tell you, if the source output, (the source is a DVD player, CD player or Tape deck etc.) is

high then the amplifier may distort with the volume control at 12 o`clock but on the other hand if

the source has a low output the amplifier may not distort until 3 o`clock. The only way to tell is by

listening carefully to the music quality. Don`t turn the volume control any more if the sound

becomes harsher, less tight and a bit blaring. That holds even if the volume control is less than half

way.

IT IS ABSOLUTELY VITAL YOU READ

THIS NEXT SECTION!

OTHERWISE IT COULD CAUSE YOU A

LOT OF NEEDLESS EXPENSE

TIMES WHEN YOUR SPEAKERS ARE AT MOST RISK FROM YOU.

1: Parties are the most common cause of speakers being damaged by too much power or by distortion, it often

happens because of a desire to have the music loud. Distortion is harder to detect because it is masked by lots

of other noise.

2: After you have been listening to the music for a while there is a natural temptation to turn up the volume. This

is because your ears lose their sensitivity.

3: Turning up the volume so you can hear the music in another part of the house or outside. Instead either

install extension speakers or have long speaker leads.

4: Your children, (if you have them), when you are not present often have the stereo distorting. Either fix it so

they can`t turn the stereo on or educate them about the expensive damage caused by having the volume too

high.

5: After you have been to a loud concert or live gig. Once again your ears have become less sensitive.

6: When you are in a state of intoxication is another time when there is a temptation to turn the volume up

without care.

The best way to avoid the above potential problems is at a time when you are fresh, turn the volume control

up until the quality of the sound changes as described previously. Take note of that position and make sure, no

matter what the circumstances, the volume control is not turned above that point. If at that point the volume is

not loud enough there is only one solution, it means you have to purchase a larger amplifier and, if required,

larger speakers.

CONNECTING YOUR

SPEAKERS

• Depending on the model you have purchased connection can be done either by using bared wire, 4mm

banana plugs or with 8mm spades. If you choose to use bared wire for our three way terminals, simply unscrew

the nuts and you will find under the nut a hole to push the wire into.

• We do not supply speaker cable with the speakers because every installation is different. There are though,

some important points to note. Keep the speaker cable as short as practical and use good quality cable. As a

guide if the cable is more than 5M then the conductor diameter must be greater than 1.5mm (18 Gauge) at no

stage is it suitable to use wire diameter less than 1mm (22 Gauge). The longer the run of cable the thicker it

needs to be.

• When connecting the speaker to the amplifier it is very important that the positive (+) terminal on the amplifier

is connected to the positive terminal on the speaker. In most cases this means that the red terminal on the

amplifier is connected to the red terminal on the speaker. Likewise the black terminals are connected to each

other. Failure to do this will result in a reduced bass performance and loss of stereo image.

• Never allow the two conductors in the speaker cable to touch each other, this could cause damage to your

amplifier.

• In the case where cable is already wired through the house or the cable has no markings contact your Hi Fi

specialist for advice.

Very important please note: What we state in this section relates only to the AARON LOUDSPEAKER

product, we are not responsible for any nominal specifications quoted by any other manufacturers that

may be inaccurate.

It is important that you understand a little about your speakers impedance for two main reasons. One is to

calculate how much undistorted power your amplifier will deliver. Secondly to check that the speaker`s

impedance is suitable for your amplifier or if it`s safe to have two speakers on the output of each channel. The

speaker input resistance is quoted as the “nominal impedance” this is what you base all your calculations on.

1: If you wish to calculate the output power from the amplifier then you must first look at the amplifier

specifications. It will usually give you an output rating for 4 ohms and 8 ohms. If the nominal speaker value is 8

ohms for example, then the amplifier`s power rating for 8 ohms is the one you have to allow for. Note: If the

speaker`s nominal impedance is 6 ohms (which is the case with some models on the Aaron range) then the

maximum undistorted power from the amplifier will be half way between the 4 ohm and the 8 ohm rating.

2: It is safe to have a speaker with a nominal impedance greater than the amplifiers minimum output rating.

But care must be taken not to use a speaker or speaker combination that is below the amplifier`s minimum

impedance capability. Having said that, most reputable amplifier manufacturers allow for a small safety margin,

for instance it is not likely to cause any problem if you connect an “AARON” 6 ohm speaker to an 8 ohm rated

amplifier output. Should you wish to put two speakers on each amplifier output, a little more care is required.

Below is a list of safe combinations that can be used with the most high quality, modern amplifiers.

Main speaker (ohms) 16 16 8 16 6 8 8 6

&&&&&&&&

Second speaker(ohms) 16 8 16 6 16 8 6 8

If your combination does not fit any of the above seek advice from the amplifier manufacturer before turning

the system on. Note: a 6 plus 6 ohm connection may be possible but check first as the amplifier will need to be

rated into 2 ohms to make this combination safe.

BI-WIRING

Connect cable to these terminals for

midrange frequencies. Please take care that

positive and negative are not mixed up.

For Bi-wiring remove gold bars.

Connect cable to these terminals for high

and low frequencies. Please take care that

positive and negative are not mixed up.

SPEAKER INPUT IMPEDANCE

The advantage gained by bi-wiring is to stop back EMF from one circuit in the speaker interfering with the

other. For best results, two power amplifiers should be used. However good results can be obtained by

connected two twin wires, one to each banana set on the speaker, and the other ends connected together at the

amplifier output.

SURROUND SOUND

SPEAKER PLACEMENT

Speaker placement can completely alter the sound of your speakers. At Aaron we spend a lot of time and

effort to design speakers that are not so position critical, but there will still be some variation from one position to

another. Due to the many different listening environments it is impossible to make cut and dry rules for the best

position for your speakers. Put them where they sound best to your ears, by using trial and error.

We can however list some very helpful hints to speed up your speaker positioning. Placing them near

corners will increase the bass, whereas if you mount them on a wall or put them on a stand they will have less

bass. If you have shaggy carpet you should attach spikes to the speakers. A bare timber floor may often require

you to put the speaker on a small stand or on some bricks. A double brick home will tend to increase the bass

output whereas a timber house causes much less bass. A brick veneer home will be somewhere in between.

Also the amount of soft furnishings (carpet, curtains, lounge etc.) in your room changes the sound - the use of

more soft furnishings will deaden the sound.

FOR HCC-600, HCC-300, HSS-600 AND HSS-300

In order to best appreciate the wonderful spatial image our centre channels and surround sounds can create

in your room, it is important that you take note of what we call best positioning practice. We understand you may

not be able to adhere, to the letter, all of our recommendations. That’s why we designed our speakers not to be

too position critical. Following are the ideal placement positions.

In the case of the centre channel it should be either placed directly under or above the TV. The optimum

position is at, or slightly above, ear height when you are sitting down. Note; if this is not possible don’t worry, as

the sound image quality will not deteriorate a great deal if you place them outside this area. Also note it is

possible to use two centre channels each side of the TV placed in the tower orientation.

The HSS-600 is a little more complex but the general principal is to place them directly each side of your

sitting position slightly above ear level. Being a genuine balanced bi-polar there is no left hand side or right hand

side speaker. You may wish to use blue tack under the four rubber buffers to stop any chance of vibration or

speaker swinging, plus it may also reduce the chance of pant damage to your wall. Due to the many variations

of room shape, size and absorption characteristics the following points should be noted:

1) If your sitting position is against the rear wall then the HSS-600 should be mounted 500mm from the rear

wall. However the HSS-300 can be mounted in the corner.

2) If the surround sound image is not giving you enough sound coming from behind them move the HSS-600

closer to the rear wall, vice versa if the image is too much at the rear.

3) Moving the HSS-600 back from level to your listening position will have two other effects. The first is to

slightly increase the brightness of the rear speaker’s sound and the second will be to make the speaker appear

to spread the sound around a little less.

4) Installing the HSS-600 higher will raise the perceived image but as the speaker is raised the sound will

become very marginally less bright.

5) If you have two rear speakers at different distances from your listening position, just adjust the left and

right rear channel volumes on the amplifier so both rear speakers are as loud as each other.

MOUNTING OPTIONS

On the back of the HSS-600 you will see two metal key holes. These can make your installation very easy

because all that is required are two screws on your wall. It is important though, that you make sure the screws

are fixed securely enough to hold the speakers weight.

There is an added mounting option we have provided for you in the HSS-600, HSS-300 and HCC-300. They

each have a 3/8 whitworth screw thread mounted in the back of the cabinet. This thread suits the best wall

mounting bracket on the market (in our opinion). The bracket is called the “Maxi Bracket”. If your retailer does

not stock them you can ring Altronics in Western Australia to find out who the nearest stockist is.

MAXI BRACKET

On the other hand the HSS-300 positioning is a little less complex. Again it is ideal to place them each side

of your seating position slightly above ear level and the five points mentioned above regards the HSS-600 are all

valid except for point (1). However in the case of the HSS-300 it can also be mounted in the room corners

should you desire and moving the HSS-300 back will reduce brightness if positioned flat on the wall.

ATTACHING SPIKES

By attaching the supplied spikes to

speakers it can further enhance the

sound quality, especially if the floor

construction is not rigid or covered with

carpet.

Use spike and locknut in each

corner to adjust the spike heights so

the speaker doesn’t wobble when on

an uneven floor.

If you wish to avoid scratching hard

surfaces use the supplied rubber

buffers to cover the spike bushes

ROUTINE MAINTENANCE:

• Periodically wipe the cabinets with a damp cloth using a mild detergent or you may use a polish such as

Mr Sheen.

• Vacuum the grill cloth with the brush attachment of the vacuum cleaner from time to time.

• Vacuum the grill and lightly dust the speaker diaphragms with a clean paint brush.

• Every 2 years rotate the Woofer one screw hole.

• Never use more than a small adjustment on your tone controls especially at high volumes.

• Turn down the volume when changing a record or switching from one source to another.

• Whenever changing wires, plugs, etc always turn all equipment off.

• When you get your speakers check that they have not been damaged in transit. Please keep the original

cartons in case of future need, they fold flat and take little space.

• Don`t push in the diaphragms with any force.

• Do not expose the diaphragms to direct sunlight.

• It is not advisable to place your speakers in a damp environment.

• Don`t use solvents to clean any part of the speaker.

• Consult with your Hi Fi specialist before connecting more than one speaker to each output of your amplifier.

• Never connect your speakers to the electricity mains.

• Tampering with the internal parts of the speaker may cause damage not covered by warranty.

• If a part fails, insist on a genuine replacement.

• Do not put your ears too close to the speakers or play them too loud for extended periods of time, as this

may cause partial hearing loss.

• Beware! Cats love sharpening their claws on speaker cloth.
