Tuner 

A tuning-device can be connected to this out-

put, and need not be switched between instrument
and amplifier, as is often the case. This precludes
any effect on the sound.

Headphones 

Output for stereo headphones, the

power amplifiers are then muted.

Footswitch 

The socket for the footswitch turns the

effect on or off.

Send 

Sends the effect, delivers the drive-signal for

the effect.

Return 

Effect return, returns the effect-signal to the

BASSCUBE.

Aux 

In Auxiliary input for tape, CD or drum machine.

Extern passive A passive supplementary loedspeak-
er can be connected here speaker (minimum im-
pedance 8 Ohm).

O.K.? We hope you enjoy your BASSCUBE!

• Notch filter

A notch filter subjects frequencies of a certain fre-
quency-band (in this case between 30 and 400 Hz)
to severe reduction (- 14 dB) in a very narrow band
(quality 2). This helps to reduce feedback and oth-
er annoying resonances. The special properties of
the notch filter can also be used to modify the sound.

• Compressor

All our amplifiers are dynamically controlled. The
supplementary compressor can only be switched off
completely or switched to one channel. In addition
to its function as a dedicated bass effect-device, it
can be used to compensate differences in dynamic
range between various signal-sources or to give dy-
namic support to the voice.

Further outputs:

DI-out 

The composite signal after tone control but

without effect and before master control lies on the
XLR socket. (Appropriate for a direct connection of
the BASSCUBE to a sound system.)

Line 

The composite signal after tone control, with

effect and before master control lies here. (This out-
put can be used for tape recordings). 

Active sub out 

The composite signal after tone con-

trol, with effect and after master control is connected
here. (This output can be used for active sub-woofers).
