A. AC Power Inlet - Use the supplied grounded AC power cord to connect your A 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!
B. Speaker Output – The jack is used to connect the internal 8-ohm aluminum driver.
C. Direct Output- This standard, balanced XLR connector provides a Line-level pre-EQ
and pre-Volume output signal from the A Series amplifier. You’ll usually use this to con-
nect the A Series signal to a Line-level input when interfacing with PA systems or record-
ing mixing consoles.
D. Preamp Out (Effects Loop Send)- Use this 1/4" unbalanced jack to send signal to a pro-
fessional 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 output is the same as that from the Direct Out on the rear panel.
E. Amp In (Effects Loop Return)- Use this 1/4" unbalanced jack to return signal from a pro-
fessional outboard effects processor.*
* In-line effects (such as footpedals) intended for low signal levels should be placed
between your bass and the front panel A SERIES amplifier Input and not
connected with
the rear panel Effects Loop jacks.
