Power-amplifier
Power-amplifiers with diagnostic facilities
*1×TDA8561Q amplifier for 4 × 12W(2Ωload) or 4 × 7 W or 2 × 24 W bridged application. (both at
4Ω load)
*1×TDA8562Q amplifier for 4 × 12W(2Ωload) or 4 × 7W(4Ωload)
*2×TDA8561Q amplifier for 4 × 24 W bridged application. (4Ω load)
Diagnostic control:
* short-circuit or too high temperature detection, display an error message
* signal clipping, via an icon and stepwise decrease of bass and or volume
Optional conventional power-amplifiers (without diagnostics) can be used such as two TDA1552Q for
4 × 22 W, one TDA1554Q for 4 × 11W(2Ωload) or 4 × 6W(4Ωload) or one TDA1552Q 2 × 22Win
a BTL stereo configuration.
