Description 21B3 With the amazing Bryston 21B Cubed model, we have a multi-channel amplifier dedicated to bringing Cubed Series excellence into an easy-to-manage package. Each 21B Cubed unit features three channels of premium quality amplification. One is rated at 600 watts, whilst the other two are rated at 300 watts each. Active loudspeaker customers will use the high powered channel for the bass section, and the other two channels for the midrange and high frequency sections of their 3-way systems. Since the Bryston 21B Cubed is based on the excellent 7B3 and 4B3 amps, it can also be used to power any 3 channels, for instance the front LCR in a home theatre setup. Features Balanced XLR and single-ended RCA input. 3 channels each, with fully-independent power supplies, including transformers. 600 watts into 8 ohms (and up to 900 watts into 4 ohms) for one channel.
