The SPL Router is a flexible switchbox suited for a wide variety of applications.
With it, you can easily route a stereo signal to eight stereo outputs, or eight
stereo signals to one stereo output. Switching is fully balanced using high
quality switches, and all inputs and outputs are balanced, ensuring profes­sional audio quality.

Additional features include:

• Up to +10 dB of preamplification for input signals

• Onboard headphone amp with mono switch in the output section for comfor­table direct monitoring of the selected signal

Content

Introduction

• Line output with level control allows direct connection of active speakers.
A switchable FIXED mode is provided for insert applications, which routes
the selected signal 1:1 to the output.

Hookup and Security Advices

Carefully select a place for setting up the SPL Router. The unit should be
situated away from heat sources and direct sunlight. Avoid installation in envi­ronments exposed to vibrations, dust, heat, cold or moisture. Keep the unit
away from transformers or motors or any other unit that could generate large
variations in power supply or cause electrical interferences. Do not install the
unit in proximity to power amplifiers or digital processors. You may consider
placing it in a rack containing other analog gear. Such placement can prevent
interference from Word Clock, Smpte, MIDI, etc.

• Do not open the case. You may risk electric shock and may damage your
equipment.

• Leave repairs and maintenance to a qualified service technician. Should
foreign objects fall inside the case, contact your authorized dealer or suppor t
person.

• To avoid electric shock or fire hazards do not expose your unit to rain or
dampness.

• In case of lightning unplug the unit. Please unplug the cable by pulling on
the plug only; never pull on the cable.

• Never force a switch or knob.

• To clean the case use a lint-free cloth. Avoid cleaning agents as they may
damage the chassis. Manufactured in standard 19“ EIA format, it utilises
two rack units.

• Please support the back of the unit whenever it is being mounted into a
19 inch rack (especially important when touring).

Rear Panel/Connections

STEREO INPUTS

For connection of the source signal, which will be routed to the eight outputs.
Use 1/4” TRS (stereo) plugs for balanced connections and 1/4“ TS (mono)
plugs for unbalanced signals. Maximum input level is +19 dBu.

SEND CHANNELS 1 TO 8

These connectors provide the balanced SEND signals from stereo channels
1 to 4 for connection to processor inputs. A send channel will only carry the
input signal if the corresponding switch is activated. Standard adapter cables
are readily available for these connections (Sub-D > XLR male or female or
Sub-D > 1/4“).

The Sub-D connectors are wired according to the Tascam standard:
