FCC Class B and CE Compliance
WARNING: This equipment has been tested and found to comply with the
limits for a CLASS B digital device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses and
can radiate radio frequency energy and, if not installed and used in accordance with the instructions contained in this manual, may cause harmful
interference to radio and television communications. However, there is no
guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television
reception, which can be determined by turning the equipment off and on,
the user is encouraged to try to correct the interference by one or more of
the following measures: 1) reorient or relocate the receiving antenna; 2)
increase the separation between the equipment and the receiver; 3) connect
the equipment into an outlet on a circuit different from that of the receiver;
4) consult the dealer or an experienced audio television technician.
NOTE: Connecting this device to peripheral devices that do not
comply with CLASS B requirements or using an unshielded
peripheral data cable could also result in harmful interference to
radio or television reception.
The user is cautioned that any changes or modifications not expressly
approved by the party responsible for compliance could void the user’s
authority to operate this equipment.
To ensure that the use of this product does not contribute to interference, it
3
is necessary to use shielded I/O cables.
This product also complies with European CE requirements.
Features
The DigiPatch 12x6 is an automated patchbay which routes digital
audio connections between gear equipped with S/PDIF and Adat*
compatible digital audio connectors. The DigiPatch 12x6 has the following features:
•Twelve completely independent sources: six coaxial (RCA) inputs
and six optical (EIAJ) inputs.
• Six targets: one coaxial output and one optical output per target.
• 50 non-volatile internal patch configurations can be programmed,
stored, and recalled at any later time.
• All connections are “format neutral” and can be used for S/PDIF
or Adat.
•Works with all digital audio format converters and swiss-army
knives.
• Performs simple coaxial-to-optical and optical-to-coaxial transla-
tions for S/PDIF signals.
• Built-in MIDI thru function for easy hook-up to any existing MIDI
setup.
• Multiple DigiPatch 2patchbays can be cascaded together for even
more ins and outs.
•DigiPatch can be programmed from the front panel, or controlled
remotely from a computer using DigiPatch Panel™ software for
Mac or PC included with the unit.
• The perfect companion for synthesizers, HD recorders, MDMs,
digital mixers, digital mic preamps, stand alone ADCs and DACs,
effects processors, etc.
• Single height, full rack mount enclosure.
• Rugged all steel construction.

Overview
Thanks for choosing a DigiPatch to automate your digital audio
routings. Like the name says, the DigiPatch 12 x 6 is a twelve by six
digital audio patchbay. It has twelve completely independent inputs
called sources, and six PAIRS of outputs called targets.
Patchbay connections are made from the perspective of the target. In
other words, you first choose which target to edit, and then choose
the source for that target. Once you have selected the sources for the
desired targets you can store this setup into a program and recall it
later.
If you’re already using digital audio gear you’ll find the DigiPatch to
be very easy to operate. If you are new to digital audio (and digital
audio connections) you’re facing a small learning curve. The most
important rule to remember is this:
Please Note: The DigiPatch is a simple switching matrix. It routes
digital ones and zeros from one connector to another. It can be
used for optical-to-coaxial and coaxial-to-optical conversions. It
does not “decode” or “listen to” the digital audio signals. In particular, it doesn’t know the difference between an S/PDIF signal
and an Adat signal. It will not prevent you from making nonsensi-
5
cal connections between the two formats.
Installation
Your DigiPatch box should contain this manual, the power transformer, and the unit itself. Save all packing materials in case you
should ever want to ship the unit.
The DigiPatch takes up one space in a standard 19” equipment rack.
Install it as you would any other piece of gear, but keep in mind that
digital audio cable lengths should be as short as possible.
There are no special rules for deciding which of the DigiPatch’s connectors to use with the various devices in your setup. You should
keep in mind however, that a DigiPatch target is a PAIR of output
connectors. This means that any signal that is transmitted from optical output N is also transmitted from coaxial output N. Even Adat
signals!
The most straightforward approach is to keep a one-to-one relationship between devices and I/O numbers. For example: To hook up
an Adat, connect optical input 1 on the DigiPatch to the Adat’s digital out, then connect optical output 1 on the DigiPatch to the Adat’s
6
digital in.
