Chapter 4 SetupChapter 3 The device

The device should be set up on a stable and level surface. Make sure that proper ventilation is

provided to ensure adequate air circulation and that a minimum distance of 10 cm is maintained

above and behind the device. If you would like to place further hi- components on top of the

amplier, make sure that you enlarge the distance behind the device to avoid excessive heat

build-up. Never place other ampliers on top of the tube amplier.

Selecting a proper location should be taken into consideration before setting up your

device, for example the distance to the next power outlet, avoiding areas where the

device may be exposed to direct sunlight, vibration, dust, heat, cold and moisture, as

well as keeping it away from transformers or motors.

› Never drill or screw any additional screws into the housing to mount.

› Always ensure a safe and stable installation and keep away from objects that might fall onto

it. Improper setup could lead to device instability, resulting in signicant danger and accidents.

› Given the variety of paints and polishes used on furniture today does not excluded the fact

that a chemical reaction may be caused, leaving visible residue on furniture, when the mounting

feet of the device have been placed on furniture. Therefore, never place the device on furniture

surfaces without using proper protection.

Components already connected to the device should also be unplugged from the po-

wer supply.

Make sure connections have been made accurately, this means for example left to left and right

to right.

Connecting analog end devices

Only use standard, shielded audio cables when connecting audio sources. Other cables may

cause interference. Only connect devices equipped with the appropriate jacks, in order to avoid

distortion and mismatching, which in turn could cause damage to the device. Before connec-

ting jacks, make sure the correct terminal has been selected. Audio cables/plugs, as well as the

terminals on most devices, are normally red and white to help distinguish what plug is to be

connected to what jack.

Chapter 6 General operation Chapter 5 Making connections

› Connect the loudspeakers directly to the amplier. Never use an earphone adapter or distribu-

tion box. In case of doubt, consult a specialist for further information.

› Make sure that the loudspeakers are correctly polarized, i.e. that plus to plus terminals and mi-

nus to minus terminals correspond.

› The amplier has been developed for operation with loudspeakers that have an impedance

rating of 4 to 16 ohms. Never use loudspeakers with a lower impedance rating. Speakers should

only be connected to these respective outputs. For simultaneous operation of 4 speakers (A+B),

connect speakers with an impedance of 8 to 16 ohm.

› Connect the rst pair of speakers (SPEAKER A) to the respective terminals.

› Connect the positive (+) terminal of the left speaker to the white speaker terminal marked „L+“.

› Connect the negative (–) terminal of the left speaker to the black speaker terminal marked „L–”.

› Connect the positive (+) terminal of the right speaker to the red speaker terminal marked „R+“.

› Connect the negative (–) terminal of the right speaker to the black speaker terminal marked

„R–“.

› A second pair of speakers (SPEAKER B) can also be connected analogly following this.

tons to switch back and forth between individual sources.

› Rotate the „VOLUME“ control dial in a clockwise motion to the desired listening level.

› Please note that listening to high volume levels on a continual basis could lead to or cause

permanent hearing damage. Use and try to maintain a comfortable volume level. Over a certain

amount of time your hearing will become accustomed to this volume level and sensitivity will

decrease, after which people regularly tend to increase the volume. This procedure will undou-

btedly lead to hearing loss. This also applies to when using headphones.

› You can use the „TREBLE“ and „BASS“ controls and/or the „PRESET EQ“ button to change the

sound.

› Before turning the device o, rotate the „VOLUME“ control dial completely to the left rst and
