3105 - 18W BTL Mono Amplifier Module (HA13118)

Class AB mono audio power amplifier module using HA13118 IC. High power output from a low voltage DC supply using the Bridge Tied Load (BTL) and a high gain of 55dB.

Especially useful in applications where the input signal level is low as it can be driven without requiring a separate preamplifier (e.g. a guitar practice amplifier). Will drive 4 or 8 Ohm speakers (not supplied).
