A
good general purpose stereo audio amplifier using the BA5406 monolithic power
amplifier IC. Can be used on it's own or incorporated into existing equipment.
Supplied with components for either 28dB (standard) or 46dB (high) gain. The standard gain option is ideal for general audio applications and will be more suitable with most pre-amps or PC sound cards, etc. See documentation link below for full technical specifications.
Supplied with all components (except heat sink, speakers and cables). See 3090H for the same product supplied WITH a heatsink.
