Inputs/Outputs.
Bass Guitar Inputs: There are two instrument inputs on the unit, one for Active and one for Passive basses. The
Active input is low sensitivity and lower impedance to suit the output from Active basses (Basses with powered
preamps). The Passive input is high sensitivity and high impedance to suit the output from Passive basses
(Basses with passive preamps).
Tuner Out: This output socket provides a line level signal that can be used for a permanent connection to a
tuner.
Send/Return: A serial effects loop is provided at a level of 0dB. An effects loop is an input/output that enables a
user to insert effects between the preamp/eq section and the power section of an amplifier.
Headphone Out: This output allows you to rehearse with headphones. The sound level in the headphones is
adjustable by the Gain pot.
Controls.
Gain - The input control sets the signal level through the preamp.
Equalization - This consists of Bass, Middle, Middle Selector and Treble controls.
Limiter - A limiter is a processing operation that reduces the volume of peaks to avoid clipping of amplifier.
Master - The Output control adjusts the overall level of the amplifier. Adjust this for your preferred overall stage
playing volume.
Mute -The Sound of the amplifier is switched off (Muted) when the green button is on. *Direct out is
Muted when the green button is on. And only the output from the Tuner sends a signal.
LED:
Power - Green light indicates that power is turned on
Signal - Yellow light indicates that the signal passes (Blinks)
Clip - Red light indicates that the amplifier is overloaded
Power On/Off: Red light indicates that power is on.

Rear Panel:
Power In-Power in connector / Use cable with lockable (Power Con) connector supplied by factory.
Speaker Output- Speakons. Standard chassis connectors for loudspeakers.
Direct Output Post-EQ-XLR. Balanced Direct Out.
The signal goes after the preamplifier with all the corrections. In this case, Gain influences the level of the output
signal. On the other hand, the Master does not affect the output signal. This allows you to adjust the sound in the
concert hall (FOH), and then use the Master level for comfortable sound on stage. If the Mute Button is pressed
the signal still passes to the Direct Output-Post-EQ output. This allows you to adjust the sound in the hall with
no sound on the stage (like during sound check)
Direct Output Pre-EQ XLR. Balanced Direct Out.
The signal goes straight from the bass guitar to the Direct Output-Pre-EQ. In this configuration, Gain control,
Master control, EQ section, do not affect the signal level or coloration of the sound. The sound engineer selects
the signal level and all corrections in the PA system. If the Mute Button is pressed the signal still passes to the
Direct output #1-Pre-EQ output. This allows you to adjust the sound in the concert hall (FOH) with no sound on
the stage (like during sound check).
Optional for touring and international Market :
Voltage Selector Switch 110V/220.
Fuse Holders for 115V and 220V
