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 components too close to the loudspeakers. |
