Guided Tour - Rear Panel
A. AC POWER (inlet) - Use the supplied grounded AC power cord to connect your
Hydrive Combos 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 (1/4-inch jack) – The jack is used to connect the internal 4-ohm
Hydrive hybrid cone bass speaker system.
C. FOOTSWITCH (1/4-inch jack) – Use this 1/4-inch jack to connect the optional FS2
footswitch to control SHAPE and BASS ATTACK OVERDRIVE on and off from the stage
floor.
D. GROUND LIFT (switch) – This switch disconnects the chassis ground from the
audio ground. If you experience a buzz in the PA system when using the Direct
Output, engage the Ground Lift switch.
E. Direct Output (XLR connector)- This standard, balanced male XLR connector
provides a Line-level output signal from the Hydrive Combos amplifier. You’ll usually
use this to connect the Hydrive Combos signal to a Line-level input when interfacing
with PA systems or recording mixing consoles.
F. PRE/POST (switch) – This switch selects the routing of Direct Output signal from
before or after the pre amp controls. If PRE is selected, the signal sent to the direct
output is directly from the Input. If POST is selected the signal that’s sent to the direct
output includes the Level, Compression, Shape and Overdrive plus the Bass Treble and
Equalizer.
G. Preamp Out / Send (1/4-inch jack) - Use this 1/4" unbalanced jack to send signal
to a professional 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.
H. Amp In / Return (1/4-inch jack) - Use this 1/4" unbalanced jack to return signal
from a professional outboard effects processor.*
I. AUX INPUT - Your Hydrive Combo amplifier features an AUX INPUT on dual RCA
connectors, which you can use with a portable CD player, cassette, mini disk or MP3
player. You can use the CD input to jam with pre-recorded tracks or to learn a riff from
a favorite recording.
*In-line effects (such as foot pedals) intended for low signal levels should be placed
between your bass and the front panel Hydrive Combos amplifier Input and not
connected with the rear panel Effects Loop jacks.
