COMPRESSOR CONTROL
A compressor increases low level signals and decreases
high level signals to reach more constant volume levels.
Use the COMP control (11) to achieve more or less
compression effect.
TONE CONTROL
Turn the BASS control (13) to get more or less bass.
Turn the MID control (14) to get more or less middle.
Turn the TREBLE control (15) to get more or less treble.
The PRE-SHAPE (12) activates the 800 Hz notch filter,
reducing the mid range by 12 dB.
EFFECT SECTION
The EFFECT ON/OFF button (1) switches the effect
section on or off (green LED-indication (2) on).
In CHORUS FIX position - button (3) up - the stereo
chorus preset is active. In VARIABLE position - button
(3) down - it is possible to change the following parameters
of the integrated delay circuit:
INTENSITY (4) - SPEED (5) - TIME (7) - REPEAT (8)
The SPEED control (5) changes the frequency(speed) of
the modulation from slow to fast. The red LED(6) flashes
to indicate the chosen speed.
The intensity of the modulation can be set with the
INTENSITY control (4). The TIME control (7) manages
to change the delay time from 2 to approx. 25ms. The
REPEAT control (8) sets the amount of feedback, i.e. how
often the signal will be repeated.
NOTE: Each control of the EFFECT SECTION is
designed with an extreme range to make best effects
possible. It is not useful to set INTENSITY control and
TIME control to max. position at the same time. High
frequency noise would be heard.

THE BASS PAKis a portable stereo headphone amp
incorporating best possible sounds and effects of use to
every bass player. Two or more players, each equipped
with a BASS PAK or STEREO PAK and a conventional
stereo cable can play together, each hearing his own and
the other players sound simultaneously in full stereo.
Rhythm machine or drum computer can be additionally
added to these two signals and all three can be
simultaneously recorded. Even more players can be
connected to this chain.
SWITCHING ON
To switch the BASS PAK on please install the supplied
9V battery in the battery compartment(21) at the back of
the unit or plug a stabilized 9V DC/200mA power supply
into the DC jack(22). Plugging a guitar cable into the input
jack (9) switches the unit on automatically.
The STEREO PHONESjack for your headphones(20) is
on the back panel of the unit.
Now set the TONE controls (13, 14, 15) to max.position
The EFFECT ON/OFF button (1) switches the effect
section on or off (green LED (2) on). Set it in position
OFF . Set the volume with the VOLUME control (16)
to approx. position 8.
Turn the volume pot of your instrument to max. position.
Now turn the GAIN control (10) until the output of your
instrument and the input sensitivity of the BASS PAK
match: No distortion should be heard, even when the
strings are hit hard.
TIP: The best result is achieved when you can turn
the COMP control (11) to min. or max. position with
almost no change in volume level.
CONNECTIONS
HEADPHONES:
The headset supplied with the BASS PAK has been
specially designed to deliver maximum frequency
response and acoustic compatibility. It is also possible to
use any stereo headset equipped with the compatible input
jack. Connect the headphones to socket STEREO PHONES
(20) on the back panel of the unit.
RECORDING:
The INTERCONNECTION jack (17) must be connected
via stereo cable to the inputs of a tape recorder. The output
gain will not be affected by the VOLUME control (16).
The AUX IN/OUT jack (18) may be additionally used for
recording purposes (switch SELECT (19) to position
AUX). In this mode, the output gain can be adjusted by
use of the VOLUME control (16).
All signals fed into the AUX IN/OUT socket (18)can be
recorded simultaneously with the guitar signal - in stereo!
(for example a drummachine, a playback or another
BASS PAK or STEREO PAK etc...)
AMPLIFIERS:
There are different possibilities to connect your
BASS PAK to amps:
SEND (23): mono output, no effect signal
AUX IN/OUT (18): stereo output with effect signal,
output gain affected by VOLUME
control (16)
INTERCONNECTION (17): stereo output with effect signal,
output gain not affected by VOLUME
control (16)
PHONES (20): stereo output with effect signal,
output volume affected by
VOLUME control (16).
It depends on the components of your equipment to figure
out, which of these connections are the ultimate.
Check it out by yourself!
NOTE: For all stereo-outputs please use shielded stereo
cables with stereo plug only! Other plugs will
INTERCONNECTION MODE
Jam together with other players:
You just have to connect the INTERCONNECTION jacks
