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:

STEREO OUTPUTS
These connectors provide the balanced return signal from channels 1 to 8
according to the switch positions for connection of active speakers or other
monitoring systems. The level is controlled by the LINE OUT pot. If FIXED
mode is activated (switch depressed), the return signals are passed 1:1 to the
STEREO OUTPUTS.
PHONES OUT
This stereo connector provides the same signal as the front-panel headphones
output. Its level is also controlled by the VOLUME pot on the front panel. You
can connect two headphones at a time (see page 8, PHONES OUT).
AC
For connection of the Router to AC power using the included power cord.

MIC INPUT
This connector allows you to connect a microphone and route it to eight
external devices. One possible application would be easy comparison of up
to eight mic preamps or other external processors with a single microphone.
A condenser microphone may be used, although switching noises may occur
due to phantom power. In this ca se, we recommend that you reduce the output
volume before switching.
LINE/MIC Switch
This switch allows you to easily select between two connected sources. With
the switch depressed (LED illuminates), the microphone input signal is routed
to the outputs.
NOTE: The microphone signal is only routed to the left channels; right chan-
nels will still carry the line signal (if present). Always use the left channel
(odd adapter cable numbers) when connecting to the inputs of various mic
preamps or other external processors. The external equipment‘s outputs may
be connected to either left or right channels. The MONO switch on the Router
should be activated so that the microphone signal is heard on both channels.
Front Panel
Switches „1“ bis „8“
These switches route the input signal to the corresponding sends, e.g. external
devices. A switch must be activated in order for the corresponding device to
receive the signal.
+10 dB
This switch allows you to increase the Router‘s input level by 10 dB. This is
often necessary when using commercial CD players or similar devices with low
output levels in conjunction with professional audio equipment.
LINE OUT
This pot controls the output level at the STEREO OUTPUTS. If for example
active speakers are connected to these outputs, the volume can be controlled
via the LINE OUT pot.
FIXED
This switch routes the return signal 1:1 to the STEREO OUTPUTS, bypassing
the LINE OUT level control. The Router should always be in FIXED mode when
used to switch between various insert devices.

Front Panel
VOLUME
This pot controls the level of the front- and rear-panel headphone outputs.
MONO
This switch converts the signal at the headphone and line outputs into a mono
signal. The MONO switch should be activated when mono processors are
connected or when microphones are used as a signal source (see above).
With the MONO function, it is also very easy to check for mono compatibility
of stereo effects.
PHONES OUT
This connector allows you to connect standard stereo headphones. When
using two sets of headphones (via the front- and rear-panel connectors), both
sets should ideally have the same impedance. Otherwise, they could vary
greatly in volume.
POWER-Schalter
You guessed it: this switch turns the Router on and off. The LED illuminates
when power is on.

Selection of processors at the master insert of a console
By connecting the Router to a console‘s master insert you can connect up
to eight various processors for easy comparison/selection, eliminating timeconsuming patching and re-patching.
Connect the console‘s master insert sends to the Router‘s STEREO INPUTS,
and the Router‘s STEREO OUTPUTS to the console‘s master insert returns.
Select LINE on the front-panel INPUT switch. The +10 dB switch should be
deactivated and FIXED mode activated so that the Router does not affect
levels. Now the units can be connected to the router for comparison.
Expanded source switching in connection with a console
The Router can easily expand your console‘s source inputs, allowing you to
monitor up to eight additional stereo sources. Simply connect your additional
sources (CD, DAT, TV, Video etc.) to the Router‘s RETURN CHANNELS, and its
STEREO OUTPUTS to your console‘s master input. The Router should be in
FIXED mode. You can also directly monitor your sources via the Router‘s headphone outputs.
Applications
Speaker selection
The Router can also select and/or compare various speaker systems. Connect
your stereo signal (e.g. console main outs) to the Router‘s STEREO INPUTS
and your amplifiers or active speakers to the SEND CHANNELS. The INPUT
switch should be set to LINE and the +10 dB switch deactivated.
Signal processor comparison/selection
The Router is an excellent tool for comparison and demonstration of various
signal processors (equalizers, compressors, reverb or multieffects units) in a
retail setting. Simply connect a CD player to the STEREO INPUTS, the SEND
connectors to the processors‘ inputs and the processors‘ outputs to the
RETURN CHANNELS. The INPUT switch should be set to LINE and the +10 dB
switch activated if necessary. Depending on the situation, the various processors can be compared via headphones (PHONES OUTs) or active speakers
(STEREO OUTPUTS). Use the LINE OUT pot to control the volume (FIXED mode
must be deactivated).
Mic preamp comparison/selection
Similarly, the Router can be used for comparison and/or selection of various
preamps. Connect a microphone to the MIC INPUT and set the INPUT switch
accordingly. Connect the left SEND channels to the mic preamps‘ inputs and
their outputs to either side of the Router‘s RETURN channels. Activate the
MONO switch. For accurate comparison, be sure that all preamps are set
to equal levels. If you are using a condenser mic, you will need to activate
phantom power.
NOTE: Switching noises may occur due to phantom power. We recommend
that you reduce the output volume before switching when using condenser
microphones.
