WARNING: TO PREVENT FIRE OR SHOCK HAZARD, DO NOT EXPOSE THIS UNIT TO RAIN OR MOISTURE.

The lightning flash with arrowhead, within an equilateral triangle, is intended to alert the user of the presence of uninsulated “dangerous voltage ” within the product’s enclosure that may be sufficient magnitude to constitute a risk of electric shock to you.

The exclamation point within an equilateral triangle is intended to alert the user of the presence of important operating and maintenance (servicing) instructions in the literature accompanying the unit.

Observance of polarity is essential. Double-checkconnections before turning the amplifier on. The amplifier can be damaged if polarities are incorrect.

Damage can occur to your speakers if the power rating* of each individual driver is exceeded by the amplifier. Ensure that all the drivers in your speaker system are capable of handling not only the power being delivered by the amplifier, but the energy that is likely to be generated during strong passages.

Turn amplifier ‘off’ when plugging in or unplugging input and speaker cables!!!

The AV6000 series II is equipped with raised feet so that continuous ventilation can be maintained. They help to maintain acoustic feedback into the amplifier at a minimum. They also provide a measure of protection against scratching any

surface the unit might be resting on.

Do not stack anything on top of the amplifier (preamplifier, processor, source...etc.).

Leave at least 2-3inches clearance from the top of the amplifier to the next shelf, component, etc., to ensure proper ventilation.

*If you are at all unsure of what the speaker ‘ratings’ are, contact your dealer.

Page 2

The AV6000 series II is a compact, very efficient, six channel power amplifier. It is designed to be used in all types of audio or audio/video systems.

The AV6000 series II utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized. The high quality parts complement includestate-of-the-artsolid state devices, 1% metal film resistors, computer grade electrolytic power supply capacitors, and a high capacity toroidal transformer.

The AV6000 series II operates class A predriver and AB high current MOSFET power output stages. It is capable of reproducing the most demanding audio signals at rated power levels.

- Efficient high current transformer for improved dynamics.

- More accurate and three dimensional reproduction of source material.

- Improves low level detail for smoother, more musical sound.

- For efficient and linear power delivery.

- Provides short term protection from accidental shorting of output devices and protection from thermal overload.

- Improve connections for better sound and minimized signal loss and degradation.

- Low noise resistors for better sound and a greater degree of repeatability.

- Ability to reproduce demanding recordings.

- Large capacity computer grade electrolytic capacitors for extended low frequency control and improved dynamics.

When using the level controls, first start with them turned all the way up (clockwise). Then adjust them according to your system requirements to match the sound level coming from each speaker. This is a rough adjustment for matching different driver impedances. Any fine tuning should be done by the preamplifier.

Example: When using 4 ohm and 8 ohm speakers together, the 4 ohm may sound louder than the 8 ohm at a given volume level. The level controls on the amplifier are used to match the speakers volume levels. Clockwise will increase the output. Counter

Clockwise will decrease the output.

RCA type connectors accept line input from the preamplifier’s output connectors. There are five input connectors, one for each channel, that may be used to connect the amplifier to the preamplifier.

Here is a typical preamplifier to amplifier setup:

Five way binding posts are provided. One pair for each channel. They are designed to accept a banana-typeplug or spade lug connector (shown below) and are color coded for easy identification. The red (+) post should always be connected to the speakers (+) jack. The black(-)post should always be connected to the speakers(-)jack.

Here is a typical amplifier output setup:

There will most likely be a number of cables involved in the installation of your home entertainment system. Pre-planningis essential in order to maximize system efficiency.

We recommend the following as a means of helping you reach that goal:

Make a diagram of your proposed system by laying out the relative location of each component in the system. Then lay out the proposed cable runs between them. Number each cable and record its length on the diagram for future reference.

Cable runs are critical in that they must be kept away from sources of power radiation (amplifiers, power cords, heaters, etc...). For the sake of safety, they should also be kept out of traffic areas.

The process of optimizing the system will include the type of cable, the length of the run, and the obstructions it must deal with along its run. Your dealer can advise you on the products available and their relative merits. If building custom length audio cables is not your strength, your dealer should be able to help you with that as well.

When possible, use a separate AC power line for the amplifier, one that is not shared by any other component in the system of any other house hold component.

Before doing anything, ensure that the power switch on the amplifier’s front panel is in the ‘off’ position.

Again, it is recommended that you locate a separate AC power outlet for the amplifier, one that is shared by any other audio component in the system or any other house hold component. This will eliminate the possibility of the amplifier ‘modulating’ the power being supplied to the component and compromising the signal originating from that component.

Locate the AC power cord provided with the amplifier and plug it into the power

input receptacle in the rear panel.

Page 7

Connect the audio cables from your preamplifier’s output to the corresponding input connector on the amplifier.

Connect the wires from your speakers to the appropriate outputs on the amplifier. It is absolutely essential that you observe correct polarity in these connections.

Double check all connections.

Connect a playback unit (CD, VLD, Tuner, etc...) to the preamplifier. Turn the volume on the preamplifier to minimum. Turn on the preamplifier, then the amplifier (in that order). Set source on the preamplifier to the playback unit you’ve just connected. Turn volume up slowly and music should be heard from all channels. If this is not the case, double check your installation.

Should you encounter any problems that cannot be traced to the source or the material being played, consult the “TROUBLESHOOTING” section on page 10.

A control is provided on each AV6000 series II amplifier to allow remote switching of mute on/off. The preamplifier’s control output, such as is provided with B&K series preamplifiers, can be utilized to provide a control signal to the AV6000 seriesII. If more than one amplifier is being controlled, the control signal can be extended to include each successive unit by simply running an RCA type audio cable from the CTRL OUT connector of the first amplifier to the CTRL IN connector of the next unit (commonly referred to as ‘daisy chaining’). An example of how to connect two amplifiers is illustrated if figure E.
