B&K VMR-6.5.4 User Manual

THE VMR- 6.5.4 - ITS PURPOSE AND FUNCTION

An exciting and reliable source of high fidelity, audio signal amplification, the VMR-6.5.4 offers excellent versatility
and cost effectiveness for most multi-channel, home entertainment systems.

The VMR-6.5.4 is primarily a 6 channel amplifier capable of delivering a clean, fully musical. 60 watts r.m.s. power
output per channel(8 ohm load). As well, the VMR-6.5.4 offers a 'bridging feature which allows those 6 channels to
be combined into three more powerful Channels.This presents an opportunity to use the VMR-6.5.4 in a number of
configurations for a variety of uses; the standard 6 channel mode; or a 5 , 4 or 3 channel mode. Such versatility
makes the VMR-6.5.4 a particularly compact source for a multiplicity of surround -sound or multi-room applications.

While the B & K Components Ltd. VMR-6.5.4 is engineered to interact harmoniously with all popular sources and
line stages, the match that approaches perfection is that of being driven by any one of the excellent B & K
preamplifiers presently available.

DESIGN AND CONSTRUCTION

The VMR-6.5.4 utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent and
highly musical sound can be realized. The high quality parts compliment includes state-of-the-art solid state
devices;1% metal film resistors; computer grade electrolytic power supply capacitors and a high capacity toroid
transformer.

The VMR-6.5,4 operates class AB employing very high current MOSFET power output stages. As such it is capable
of reproducing the most demanding digital or analog recordings at full rated power levels.

SETTING UP THE VMR-6.5.4

Placement of the amplifier is important and requires some pre-planning. In order to eliminate interference being
induced in the amplifier by other components, it must be physically located a safe distance away from all source

components. This will avoid their being influenced by the fields being propogated by the amplifier when it is under
heavy load.

Ideally the VMR-6.5.4 will be located near the speakers. This will minimize the adverse effects of inductance,

capacitance and any damping effect that might result from speaker wires interacting with the amplifier.

The VMR-6.5.4 is equipped with raised feet so that continuous ventilation can be maintained. As well, 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.

Note: Acoustic feedback can be identified as tow frequency vibrations which are not part of the signai from
the source material. They also have a tendency to become louder and less controllable as you increase the
system volume. The most common source of acoustic feedback interference is the result of having the
preamplifier and source com ponents too close to the loudspeakers.

SYSTEM INSTALLATION

CONSIDERATIONS

There will most likely be a number of cables involved in the installation of your home entertainment system.
Therefore, pre-planning is essential in order to maximize system efficency. We recommend the following as a means
of helping you reach thaf goal.

- Use the diagram on page 8 of this manual, or make your own diagram of your proposed system, to lay out the
location of components, the VMR-6.5.4. and the proposed cable runs between them in the room. Number each
cable and record its length on the drawing for future reference.

For example, " # 3 ■ IN ■ 12"' denotes input cable from source channel # 3 and that it is 12 feet long.
" # 1 OUT (L.REAR) - 20" denotes that # 3 speaker output has been assigned to the left rear speaker and that

its length is 20 feet.

- Cable runs are critical in that they must be kept away from sources of power radiationfamplifiers, 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 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.

if you would like to utilize the bridging option which converts two channels in order to create a more powerful single
channel, see the ALTERNATE SYSTEM CONFIGURATIONS section.

For the standard configuration of one channel source per input, most of the planning will be In determining which input

you wish to apply to which channel. A typical connection diagram is shown in Fig. 3(a). For other methods of setting
up your system, see the section ALTERNATE SYSTEM CONFIGURATIONS.

MAKING THE CONNECTION

1. 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 VMR-6.5.4, one that is not shared by any
other audio component in the system. This will eliminate the possibility of the amplifier 'modulating' the power
being supplied to the component and compromising the signal originating from that component.

2. Locate the AC power supply cord and plug it into the power input receptacle in the rear panel. Do not connect it
to the AC power supply as yet.

3. Connect the audio cables from your preamplifier's output to the selected channel's input connectors.

Make note of the input number(as suggested in the "Considerations" section above) so that the correct
speaker cable can be connected to the speaker output with the same number, A rear panel connection
guide is shown in Fig. 2(a).

4. Connect the cables from your speakers to the appropriate CHANNEL output.
