Rear Panel Functions
1. Remote sw reverb
- To turn the Reverb effect on/off remotely, use a standard corded foot switch
with 1/4 Jack, (Latching)
2. Speaker Output Jacks-
There are two sets of speaker output jacks, and the nominal impedance
of the Roadie Bandmate 15 is 8-16 ohms. The Bandmate 15 comes standard with a 16 ohm Cele-
stion Vintage 30 speaker, which should be plugged into the single 16 ohm output. The amplifier
can power a pair of 16 ohm speakers and combine them to an 8ohm load, or you can run a single
8 ohm speaker, by plugging into the output jacks marked 1 x 8 ohm or 2 x 16ohm.
3. Fuses
- In the unlikely event that a tube fails, the Bandmate 15 is protected by a 1 Amp slowblow
fuse for 115v and 230v, and a Voltage fuse 315mA.
Please consult us or a qualified tech for assistance in the event of a fuse blowing.
4. Power Switch
- To select between 115v and 230v A/C power sources.
5. A/C Input
- Connects the amplifier to A/C power via the power cord supplied. Unless otherwise
specified, your amplifier is designed to operate on 115-230 volts A/C, 60 cycles.

Biasing your Bandmate 15
The Bandmate 15 is a cathode bias (self bias) amplifier and as such does not require a bias
adjustment when changing tubes. Please use matched pairs of output tubes for maximum
performance. The Bandmate 15 can only use matched pairs of EL84 power tubes.
