THE STEREO PAK
is a portable stereo headphone
amp incorporating best possible sounds and effects of use
to every guitar player. Two or more players, each equipped
with a
STEREO PAK
or
BASS PAK
and a conventional
stereo cable can play together, each hearing his own and
the other players 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
STEREO 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 PHONES
jack for your headphones
(20)
is
on the back panel of the unit.
Now switch the SOUND SELECTOR
(11)
to position
"NORMAL".
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
STEREO PAK
match:
No distortion
should be heard, even when the strings are
hit hard.
We designed the
GAIN
electronic to slightly increase bass response
when low-output pickups are used (such as single coils) and to
slightly increase presence when turned more to low position in
connection with high-output pickups (such as humbuckers, etc.).
SOUND SELECTOR
Choose one of the following four sounds with the SOUND
SELECTOR switch
(11)
:
NORMAL - CLEAN - OVERDRIVE - DISTORTION
SPEAKER SIMULATION
The integrated speaker simulation circuit can be switched
to three different positions with the switch
(13)
:
OFF
- SPEAKER SIMULATION off.
FIX
- SPEAKER SIMULATION on; fixed preset.
VARIABLE
- SPEAKER SIMULATION on,
TONE control
(14)
is active, you can set the desired sound.
The TONE control
(14)
shifts the cut off frequency to get
more or less treble.
(upper harmonics)
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 EFFE CT 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!
CONNECTIONS
HEADPHONES:
The headset supplied with the
STEREO 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
STEREO
PAK
to guitar 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 cause a
short on one channel and will shorten battery life.
INTERCONNECTION MODE
Jam together with other players:
You just have to connect the INTERCONNECTION jacks
(17)
or the AUX IN/OUT jacks
(18)
of two or more
STEREO PAKs
or
BASS PAKs
via simple stereo cables. To
achieve a perfect mix of all devices, adjust the GAIN
control
(10).
EXAMPLE:
RECORDING with one
STEREO PAK
plus one
BASS PAK
plus DRUMMACHINE:
Connect the drummachine to the AUX IN/OUT jack
(18)
of the
BASS PAK
. Switch SELECT
(19)
to position
INTERC.. Connect the
BASS PAK
to the
STEREO
PAK
with a stereo cable via the INTERCONNECTION
jacks
(17)
of each unit. Connect channel 1 + 2
(or left and
right)
of your tape deck with stereo cable to the AUX IN/
OUT jack
(18)
of the
STEREO PAK
. Switch SELECT
(19)
of this unit to position INTERC..
Ready - let the tape go!
EXTERNAL EFFECT DEVICES
You want to have
stereo effect
units, like digital delays or
reverbs, linked to your
STEREO PAK
? No problem.
Connect the mono input of your effect device to the SEND
jack
(23)
of the
STEREO PAK
. Then connect both stereo
outputs of your effect device to the AUX IN/OUT jack
(18)
- SELECT switch
(19)
to position INTERC. If you use a
mono effect
device, its output should be connected to the
RETURN jack
(24)
of the
STEREO PAK
.
IMPORTANT NOTES:
Please use high quality, shielded cables only. Dont take
your
STEREO PAK
in the shower - in other words: please
treat it carefully, only cleaning it with a dry duster. Use
good, leakproof batteries only. Please realize: battery life
is limited and you are working with a high powered unit.
Disconnecting the INPUT switches the unit off and will
save battery life!
O.K. - now lets go: enjoy your
STEREO PAK
!
CAUTION:
Prolonged listening at high levels may be hazardous
to your hearing!
