About the Reference 200.7 S2

The B&K Reference 200.7 S2 is a high-power 7-channel amplifier designed for demanding audio and home theater systems. Hand-assembled in Buffalo, NY, it features Class A predriver and AB MOSFET output stages for effortless reproduction of dynamic music into difficult loads. It supports both balanced XLR and unbalanced RCA inputs, with switches to configure pairs of channels accordingly. A 5-24V DC trigger system enables remote standby control. Drivers can be paralleled per channel but system impedance must not drop below the amplifier's nominal rating (e.g., two 8Ω speakers = 4Ω minimum). Known for its solid build, warm sound signature, and reliability when serviced, it's ideal for multi-channel setups or pairing with bright speakers like Polk LSI series. Production around 2005; units often weigh 76 lbs and measure heavily built.
