Using the product

1. Insert a 9V battery into the device or connect a suitable power adapter (not supplied)
that provides 9V to the 9V connector (centre negative ). Turn on the
unit with the ON / OFF switch, the ON / OFF LED will turn red.

2. Connect an electric bass to the INPUT jack using a shielded 1/4" jack cable. Watch the
CLIP LED while playing. If it often turns red, turn the GAIN control counterclockwise. If
the LED is still red, the instrument's output level is too high. Then set the INPUT switch
to the -10 dB position.

3. Connect an amplier to the OUTPUT socket. You can connect headphones to the
PHONES socket. The DI signal for feeding into a mixing console is present at the D.I. OUT
output. To feed the dry input signal to other devices, connect them to the THRU socket.

2 BASS bass control
3 MIDDLE mid control
4 9V

connector for 9V power adapter ( , not included)
5 FREQ controls the mid control center frequency (150Hz-8kHz)
6 TREBLE treble control
7 CLIP LED lights up red on excessive input signal, otherwise green
8 THRU 1/4" output, delivers the looped-thru INPUT signal
9 GAIN controls the input gain
10 INPUT 1/4" instrument input
11 COMP. controls the compression ratio if function enabled
12 LINE IN 3.5mm mini jack input to connect line level devices
13 ON/OFF LED lights up red when the device is enabled, LED lights up green
when the de vice is disabled (DI and INPUT switch remain enabled)
14 ON/OFF enables / disables the device
15 INPUT switchable input signal attenuation by -10dB
16 D.I. Ground / Lift switch for XLR DI out
17 COMP. enables / disables the compressor function
18 COMP. LED lights up red on activated compressor function, otherwise green
19 D.I. OUT XLR signal output for direkt input into the mixing console
20 THRESHOLD sets the level at which the compressor processes the signal
21 PHONES 3.5mm mini jack headphones output
22 VOLUME sets the volume of all outputs, except THRU
23 OUTPUT 1/4" output to connect an amplier

4. Use the EQ to adjust your desired sound. The FREQ control allows you to adjust the
centre frequency of the mid control between 150Hz and 8kHz. The BLEND control
adjusts the ratio between the dry signal (left stop) and the EQ-processed signal (right
stop).

5. To activate the compressor function, press the COMP. switch, the COMP. LED will turn
red. Use the COMP. control to set the compression ratio. The THRESHOLD control
determines the level above which the signal will be processed by the compressor.
