2V DIRECT IN BYPASS FUNCTION
The Signature amplifiers have a direct in bypass
feature for the optimum sound quality when running
the system from a DSP or DSP equipped source
unit. To access this feature the small section of the
bottom plate needs to be removed. Depending on
which S-series model you have, the bypass is put
on different places on the amplifier. The amount of
jumpers on the amplifier is based on the amount
of channels it has:
S1 (1-channel)
S2 (2-channel)
Gold plated PCB jumpers located on
the circuit boards are used to select the
Bypass function. These jumpers need
to be moved to bypass the pre-amp /
filter section.
Professional Tip:
ACTIVATE 2V DIRECT IN BYPASS PT.1
The default setting of the amplifiers when they
are sold is that the direct in bypass function is
OFF. To use the function, first disconnect the
amplifier from all types of connections and remove
the small bottom panel plate from the amplifier.
There are 4 screws that needs to be removed.
Locate the jumpers on the circuit board and move
the jumpers from 2 pins right-sided to the 2 pins
left-sided. WARNING! All jumpers should be moved
to the same position. If any aren't moved then an
optimum setup will be near impossible to achieve.
Professional Tip:
ACTIVATE 2V DIRECT IN BYPASS PT.2
On Signature 1 and Signature 2 the jumper(s) need to
be in the ON position to activate the bypass function.
On Signature 4 move the jumpers to the 'BPS' position.

Professional Tip:
DIRECT IN BYPASS vs CROSSOVER
When the direct in bypass mode is turned off, you
can use the crossover functions on the side panel
normally to adjust your sound systems performance
(input sensitivity 1-4V). (Note:) When the bypass
feature is activated NONE of the front panel controls
will function. The input signal will then go in as a 2V
direct signal input in the amplifier (input sensitivity
fixed at 2V).
Bypass is only compatible with systems that have
a DSP or DSP equipped head unit. All functions
such as crossovers and level adjustments need to
be set up on the DSP.
The direct in bypass mode is used to achieve the
optimum sound quality when running the system
from a DSP or DSP equipped source unit. This
removes the pre-amp and filters from the signal
path which improves both signal to noise ratio and
sound quality.
WARNING! The jumpers should never be removed
from the amplifier. If you remove the jumpers the
amplifier will have no output and will not function
properly.
