875HT EIGHT CHANNEL POWER AMPLIFIER

INTRODUCTION

Thank you for choosing the 875 Eight Channel Power Amplifier. Bryston welcomes any suggestions you may have, or comments regarding the operation of your amplifier. We consider you, our customer, to be Bryston’s most important resource, and your opinion is very much appreciated.

DESCRIPTION

The 875HT is a modular multi-channel audio power amplifier design of 8 x 75 Watts per channel. It is essentially 4 stereo amplifiers. Each stereo pair selects from balanced or single ended inputs, and each stereo pair may be bridged to form a single higher power amplifier channel. The gain of the balanced input is 23dB and the single ended input is 29dB.

The power up sequence of the 875HT may be controlled from a 12v control voltage. The 875 uses ‘soft start’ power con- trol circuitry to eliminate high inrush currents when A/C power is applied.

WARRANTY (see back page for details )

SHIPPING BOX & PACKING MATERIAL

Please keep the original shipping box and all packing material. This will ensure the amplifier is protected in future trans- port. In the unlikely event you have a problem and must return it for service you must use the proper packing material. Ship the amplifier only in the original packing material, as the unit is not insurable by carriers otherwise.

INSTALLATION

The most important installation consideration is ventilation. The 875 series amplifiers are a convection-cooled. Unrestricted air-flow across its heat sinks is a must. For this reason do not install anything directly above it. Allow 3.5” (2u) to 5” (3u) inches of space above and to the sides of this amplifier. Do not install directly above other heat generating equip- ment. Any 875 channels thermally shutting down during operation indicates insufficient cooling, and a remedy must be found for cooling the amplifier. Provide a minimum 6” space to the rear of the 875 for ventilation and dressing cables to and from the amplifier.

Never operate the 875 in a vertical position.

WIRING THE 875HT (also see rear panel description )

Speaker wires should be as short as practical. Use quality wire, and if runs are more than 3 meters use at least 12 gauge wire. The speaker binding posts will accept wire up to 3 gauge in size. Bryston can custom build cables for your applica- tion.

PA/C power:

Before plugging in the power cord be sure your 875 is specified for the correct A/C voltage for your locality. The voltage is listed by the power input connector. Never lift the safety ground to the amplifier or remove the ground pin from the plug.

PPower line conditioners:

The 875’s performance will not be improved by the use of power line conditioners. In fact most of the time they restrict the flow of current in the power line to the amplifier thereby reducing performance at high output levels.
