Connections:
1.
IN
is the signal source input.
2.
THRU
is a buffered output for the unprocessed signal split from the
IN jack.
3.
SEND/RETURN
is a series effects loop for external processing.
The SEND out can also be used as an additional output.
4.
OUT
is the main output designed to connect the preamplifier to a
power amplifier
(RETURN or POWER AMP IN on combo amplifiers,
INPUT on power amplifiers).
5.
AUX IN
is an external audio input
(the signal from the AUX IN is only
heard through the PHONES output).
6.
PHONES
is a headphones output.
7.
BALANCED OUT
is a balanced output.
8.
POWER IN
is a power supply input. The power requirements are
12V DC 650mA.
9.
microSD
is a microSD card slot.
Controls:
10.
GAIN
controls input signal amplification. It can go from a
crystal-clear sound all the way to a classic California-style overdrive.
11. The
BASS, MIDDLE
and
TREBLE
knobs constitute a classic
3-band passive EQ with a mild frequency correction effect and a
characteristic mid scoop at 400 Hz.
12.
MASTER
controls the volume of the signal coming from the OUT
jack.
13.
VOLUME
controls the volume of the signal coming from the
PHONES and BALANCED OUT jacks.
The MASTER and VOLUME knobs work independently.
14. The
TOP
switch controls the signal’s high frequency harmonic
content. The “+” position accentuates the highs and the attack. The ”-”
position provides a milder sound by cutting the high frequencies. The
neutral position does not affect the signal in any way.
15. The
GND
switch allows to override “ground loops” that can
negatively affect the signal when using XLR connections. In the lower
position of the switch, the preamp’s “ground” is connected to the
signal receiver’s “ground”. In the middle position, the “grounds” are
disconnected. In the upper position, the “grounds” are connected and
an additional filter is used to remove interference.
The optimal setting of the GND switch is selected by ear: there should
be a minimum amount of 50Hz hum and interference.
16. The
CAB
switch selects one of the two built-in cabinet impulses:
•
The “A” position selects the impulse recorded from a SUNN 200s (2х
15) cabinet.
•
In the middle position, cabinet simulation is disengaged.
•
The “B” position selects the impulse recorded from an AMPEG
SVT-810E (8х10) cabinet.
When using a microSD card, impulses are loaded from the
corresponding folder on the card. The CAB switch affects the signal
from the BALANCED OUT and the PHONES OUT but does not affect
the signal from the main OUT.
Loading impulses from a microSD card:
Before using a microSD card, make sure it is formatted to the FAT32
filesystem.
When the memory card is used for the first time, a “Shift_IR” folder is
automatically created on it. The folder contains two more folders (“A”
and “B”, corresponding to the CAB switch positions) in which the
default impulses are stored. To use external impulses, replace the
default ones with your own files. The supported impulse format is
24bit 48kHZ WAVE PCM1.
To restore the default impulse files, insert a blank microSD card into
the device. This will create a “Shift_IR” folder containing the default
files. If no card is inserted, the built-in impulses are used.
