Samson 210C User Manual

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.
