Power-amplifier
Power-amplifiers with diagnostic facilities
*1×TDA8561Qamplifier for 4 ×12W(2Ωload)or4 ×7 Wor 2 ×24 Wbridged application. (both at
4Ωload)
*1×TDA8562Q amplifier for 4 ×12W(2Ωload) or 4 ×7W(4Ωload)
*2×TDA8561Q amplifier for 4 ×24 W bridged application. (4Ωload)
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
Optionalconventional 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.
