Product Description
The Bryston 4B-ST stereo amplifier consists of two amplifier modules, each with its own +/- 85v power supply. Each of the two amplifier modules uses eight of Bryston's custom power transistors for a total of 16 output devices. The two channels may be operated independently (at 250 watts per channel @ 8 ohms, 400 watts @ 4 ohms), or combined to form a single 800 watt monaural amplifier into 8 ohms.
Bryston amplifiers come equipped with one unbalanced RCA (single-ended0 and one balanced combination XLR 1/4 inch jacks per channel. All inputs use fully discrete buffer circuitry. The balanced inputs use a combination 3-pin XLR and 1/4" tip-ring-sleeve input connector. All input connectors are gold-plated and should only be used with high-quality gold plated interconnect cable, as a poorly plated connector will eventually corrode through the gold flash.
Bryston ST series amplifiers have gain levels that match the type of input used. This provides overall system gain that is consistent whether RCA, XLR/Phone bridged or stereo is selected.
