INTRODUCTION

This manual is designed to help you get the most out of your L2 audio IM/IMP speaker enclosure.

The IM range refers to passive or un powered speakers. These will need an external amplification

source. The IMP range refers to active or powered speakers. These speakers have built in

amplifiers so only require a signal source. There are 4 models in each range, 8”,10”, 12” and 15”.

All models feature 2 way speaker configurations, a LF (low frequency) woofer and a HF (high

frequency) tweeter or compression driver. The woofer has been carefully selected for optimum

performance and has an aluminium chassis. The HF is a titanium diaphragm and a light mass

voice coil, enabling it to reach frequencies as high as 18KHz. There is a quality crossover unit built

in that separates the high and low frequencies. All models are made of the same high impact

injection moulded polymer and can be used for FOH (front of house) PA applications, installation

or as stage monitors.

IM Passive Series.

1. INPUT on the IM8H is via ¼” jack or binding posts. Input on the IM10, IM12 and IM15 is via

speakon® input . The speakon® has a parallel input and output. These inputs receive the

powered signal from an external power amplifier or powered mixer.

IMP Powered Series.

1. XLR/Jack Input and output sockets, electronically balanced. The in XLR socket allows

connection of a low level signal source such as a microphone. The out XLR is parallel and

can be used as an output to link to another speaker into the jack line in (2) (Jack only on

IMP8)

2. LINE. Input is a ¼” jack for line level or instruments. This is the input used to connect from a

mixer etc

3. LINE/MIC. These are signal lights from either the line in or mic in inputs

4. GAIN. Regulates pre-amplification of the signal coming from the input "IN", ensuring

perfect operation of the channel circuits.

5. HIGH/MID/LOW. 3-band equalization to modify the required tone. These controls are

electronically post-gain and if boosted can clip the channel. This is indicated by the AACS

(clip light) indicator (see 9).If this occurs adjust the gain control anticlockwise. When the

potentiometers are set to "0" (indicated by a ‘notch’ in the dial) the tone is set to ‘flat’.

Clockwise will boost, anticlockwise will cut.

6. TONE (IMP8 ONLY). This is to adjust the tone. Clockwise from the 12 0 clock position will

add more treble whilst anti clockwise will add more bass.

7. VOL. Volume controls the signal level. Optimum performance is achieved with this set at

around 4 or 5 (level with ‘0’ on the tone controls)

8. GND/LIFT. 2-position selector for separating the signal source ground and the amplifier

ground circuits. ON: the signal ground is electrically disconnected from the amplifier ground

circuit (the chassis). If hum is heard in the speakers, the ON position breaks the ground

loop. This is often the cause of the interference. OFF: the ground of the input signals is

electrically connected to the amplifier ground circuit (the chassis). USE GROUND LIFT ONLY

WITH BALANCED SIGNALS.

9. CLIP (Automatic amplitude clip system) when the audio signal reaches the dangerous

threshold for the transducers, this circuit will automatically cut in reducing the amount of

signal in order to protect the speaker.

10. PWR . An LED light will indicate when the power is switched on or off.

11. AC power socket. Is used to connect the unit to a power supply via enclosed power.

Caution: ensure the source voltage matches the voltage of product before turning on the

unit.

12. FUSE HOLDER. The fuse holder is for containing the fuse, which is a safety device that

protects the AC supplies circuit of the unit. Caution: if the fuse blows, it should be replaced

with the same type and specification, if the fuse continues to blow, please refer servicing to

qualified personnel.

13. VOLTAGE SELECTION SWITCH. This switch provides two voltage selections: 115V or 230V,

please select the proper voltage depending on the voltage used.230v is used in the UK.
