Electric Bullroarer Amp

Amplifier module for the Electric Bullroarer rack

This is the internal amplifier module for the Speakers On Strings Electric Bullroarer. It is a powerful, single channel (mono) amplifier and powers the internal 60W 4-inch driver as well as providing banana plug output to power external speakers.

NOTE: this unit uses its own power feed direct from the EBR battery / power input. As it is a high power speaker amplifier it is not connected to your modular power back-plane.

The depth given (120mm) includes height for the 4" internal speaker of the EBR. If no speaker is used and the amplifier board is mounted vertically the depth is about 100mm. The amplifier can also be mounted on the back of the rack in which case the depth is about 50mm.
