What is the SLX-2?

Thank you for purchasing a ZAPCO product! The SLX-2 is an
extremely flexible dual output electronic crossover. As a member
of the SymbiLink Balanced Signal System, the SLX-2 delivers
audio performance without equal. Each output has its own
crossover frequency adjustment and can be configured as a high
or low pass filter. Both outputs can be fed individually or from a
single input signal. There is no power supply wiring necessary,
as the SLX-2 is powered via the SymbiLink balanced cable.
For this reason, the SLX-2 usually requires a SymbiLink
balanced input amplifier in the system.

Key Features

• Single or dual input capability.

• Independently adjustable crossover points.

• Selectable 12 or 24 dB slope for X2 when used as lowpass.

• Dual Frequency range for X1 - 50Hz - 1kHz or 500Hz -

10kHz.

• X2 frequency range - 50Hz - 1kHz.

• Output 2 can access X1’s highpass filter.

• Quality ZAPCO construction.

• Designed and manufactured in the U.S.A.

SLX-2 Functional Diagram

Notes:

• 24dB mode is only valid on X2’s output - lowpass mode only.

X2’s output in this mode is automatically mono.

• Frequency range switch only effects X1’s outputs - but can

effect X2’s output when output switch is set to “X1-HI”.

• When X2 output is set to “X1-HI”, the X1 FREQ control

effects both outputs. The X2 FREQ control is deactivated in
this mode.

• X2 input in not functional when the “Input Mode” switch is in

the “2CH” position. X2 input only activated by engaging the
“4CH” mode.

• Either output can be selected as highpass or lowpass. They

can be set the same or opposite of each other.

• One output can be fed into the opposite input. When doing

this, you must engage the 4CH input mode. This feature
allows the capability of “1-way” 24 dB or bandpass
configurations.
