Description
Solid state four channel power amplifier.
|
The SDA1 Four Channel Power Amplifier is designed for use with the SDP1 processor. Rated at 100 watts x 4 into 8 ohms (150 watts x 4 into 4 ohms), the SDA1 offers complete flexibility for installation in a wide range of multichannel music systems. It can be used on its own, in a four-channel system not requiring a center channel. Alternatively, either of the two channel pairs can be bridged to produce 300 watts into 8 ohms-yielding a perfect three-channel amplifier with higher power delivery to a center channel or passive subwoofer. Or, both pairs can be bridged simultaneously for a 300-watt per channel stereo amplifier. Inputs are balanced and single-ended. |
