Guided Tour - Rear Panel
1. AC Inlet - Attach the grounded AC power cord here to connect your B Series amplifier to
mains power. This cord comes supplied with the appropriate plug for your geographic area.
CAUTION: Do not use an adapter to defeat the third grounding pin on this plug or severe electric
shock may result!
The fuse holder comes from the factory with the appropriately rated fuse for your model. If you
need to change this fuse for any reason, replace it with one that has the same exact rating.
2. Speaker Output – The SPEAKER OUTPUT jack is used to connect the internal speaker to the
amplifier. Your B Series amplifier has been designed to match the internal speaker, so we recom-
mend that you do not connect an external bass speaker to your amplifier. If you do, be sure to
match the power rating of your amplifier to the connected speaker. In some cases, under pow-
ering a high power speaker can damage the connected amplifier. DO NOT connect any speaker
with any impedance rating that is lower than 8 Ohms. Doing so may void your warranty.
3. Preamp Out (Effects Loop Send)- Use this 1/4" unbalanced jack to send signal to a profes-
sional outboard effects processor.* Output level is approximately 0 dB to +4 dB and is post-EQ
and post-Shape but unaffected by the setting of the Volume control. The
signal from this out-
put is the same as that from the Line Out on the front panel (see #7 on page 4).
4. Amp In (Effects Loop Return)- Use this 1/4" unbalanced jack to return signal from a profes-
sional outboard effects processor.*
* In-line effects (such as footpedals) intended for low signal levels should be placed between your
bass and the front panel B Series amplifier Input and not connected with the rear panel Effects Loop
jacks.
