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 AV5000 series II is a compact, very efficient, five channel power amplifier. It is designed to be used in all types of audio or audio/video systems. The AV5000 series II utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized.
1. AC fuse holder 2. AC Input receptacle 3. Speaker outputs 1. AC fuse holder - 4. Amplifier control muting input/output 5. Level controls 6. Inputs Holds the AC Line fuse. This fuse is an 12 Amp / 250 Volt Slow Blow fuse. Replace with same type and value fuse only. 2. AC Input receptacle - For attaching the supplied AC power cord to the amplifier. 3. Speaker outputs - For connecting the speakers to the amplifier. Explained further on page 6. 4.
5. Level controls - For adjusting the input level of each channel into the amplifier. There are five level controls on the back of the amplifier. One level control for each channel. Explained further below. 6. Inputs - For connecting signal patch cables (interconnects) from the preamplifier to the amplifier to pass signal. Explained further below. When using the level controls, first start with them turned all the way up (clockwise).
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-type plug 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.
There will most likely be a number of cables involved in the installation of your home entertainment system. Pre-planning is 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.
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).
If a source other than a B&K series preamplifier is used to control multiple amplifiers, only the control output voltage from the source is critical. It must be within the range, as indicated on the rear panel, 5-24 volts DC is required. The amplifier will provide each successive amplifier with a control voltage of 12 volts DC for reliable operation. The amplifiers control output may be used as a source of 12 VDC @ 125 mA for other user applications as well.
