B60 INTEGRATED AMPLIFIERS INTRODUCTION Thank you for purchasing a Bryston B60 integrated amplifier. We are confident it will provide you with many years of musical enjoyment. We would welcome any suggestions or comments you may have regarding the operation of your Bryston amplifier. Bryston recommends that you retain the original shipping box and packaging material for future use if required. SETUP: You may place your B60 integrated amplifier in any convenient location, with one possible exception; if you own the remote-control version, position the amplifier to maintain a direct line-of-sight between the hand-held remote and the remote sensor eye located on the right side of the front panel. The amplifier is powered up by engaging the power toggle located on the front panel of the B60. The B60 will power-up momentarily with mute engaged, indicated by the pilot light turning red on the front panel. It will then quickly turn green signifying nor- mal function. If you have the remote control version of the Bryston B60 please refer to the section on the remote control unit. CONNECTIONS: Connect your loudspeakers, ensuring that the positive (red) and ground (black) terminals (gold-plated 5-way binding posts) on the Bryston B60 integrated amplifier are connected to the positive and ground terminals on your loudspeakers. Make certain the left and right speak- er outputs on the amplifier are connected to the appropri- ate left and right loudspeakers. Connect your CD player, tape deck and other sources to the appropriate left and right RCA inputs. The tape loop may be used to insert a surround sound processor, tape deck or other recorder into your system. Plug your tape deck or external processors input cables into the To Tape jacks and the processor or decks out- put cables into the From Tape jacks on the rear of the B60. The tape or processor loop may be monitored via the toggle switch located on the front panel of the B60. PRE-AMP OUT / POWER-AMP IN CONNECTIONS On the rear panel there are connections labeled PRE OUT (preamplifier output) and PWR IN (power amplifier input). Please refer to the rear panel illustration later in this manual for further clarity). This feature allows you to separate the preamplifier section of the B60 from the power amplifier section by removing the jumpers. Simply pull the two U connectors straight out with the power to the amplifier turned OFF. Store them in a safe place for future use. These pre-out/power-in connec- tors provide for complete separation of the preamplifier and power amplifier sections. This allows you to easily accommodate the integration of a surround sound pro- cessor into your system and still maintain the control functions available on the front panel of the B60. It also allows the independent use of the stereo amplifier sec- tion within a multi-channel audio or video system. INPUT & OUTPUT CONNECTIONS: The Bryston B60 integrated amplifier comes equipped with 4 pairs of RCA input connectors, 1 pair of tape loop connectors, 1 pair of pre-out ~ power-in connectors and 1 pair of five-way binding post loudspeaker outputs. All input and output connectors are gold plated. Only cables with high quality gold plated connectors should be used with your amplifier to avoid noise and distortion from the corrosion which will eventually appear on poorly plated or gold-flashed cable connectors. Bryston offers high quality very low capacitance interconnect cables with custom RCA connectors gold-plated to 20 micro-inches (30 times heavier than standard gold-flashed cables). Standard 1 and 2 meter, or custom length cables, are available by contacting any authorized Bryston dealer or distributor. HEADPHONE JACK: There is a quarter inch stereo (3 conductor) headphone jack available on the front panel of the Bryston B60 inte- grated amplifier. The headphone output is driven directly from the preamplifier section. We recommend the use of headphones with input impedances between 50 ohms and 600 ohms. Headphones with input impedance val- ues above 600 ohms may experience some problems attaining sufficient volume levels. The main outputs, both balanced and single-ended, will be muted when a phone plug is inserted into the headphone jack. TAPE outputs are not muted. You can adjust the volume setting of the headphones by using the volume control on the front of the B60 integrated amplifier. You may also utilize the remote control unit to adjust headphone volume if your unit is so equipped. The headphones cannot be muted with the remote control unit. Use caution when disconnecting the headphones as the loudspeakers will be immediately re-connected at the volume level indicated by the front panel volume control. TAPE LOOP: Tape Outputs: The TO TAPE outputs are selected by the rotary SELECTOR knob and are provided as a 1
