1x4 Digital Audio Opticial S/PDIF Thru Box

Thank you for purchasing the OT-14, by M Audio. The
OT-14 accepts one optical digital audio signal via TOSlink
connector, and duplicates it to four TOSlink optical digital
outputs, all on the rear of the OT-14. This allows you to
take the optical output of any digital audio source, ADAT
8-channel or S/PDIF optical format, and send it
simultaneously to four digital audio targets capable of
receiving that same optical format. The OT-14’s active
electronics assure that the integrity of your digital signal is
never compromised.

NOTE: The OT-14 will handle any ADAT or optical S/PDIF
signal having sample rates 100kHz or less, and supports
all data widths. However, since it is not a converter, it
will pass only one digital format at a time. The digital
format signal present at the OT-14 input is the digital
format that is duplicated to the OT-14 outputs, i.e. ADAT
to ADAT, or S/PDIF to S/PDIF.

The setup example that follows shows what might be a typical
mixing scenario. The output of a Hard disk recorder or the
output of a digital audio card is connected to the OT-14 input,
while a DAT, computer-based digital audio card (such as an
M Audio “Delta DiO 2496” or “DiO 2448”), a CD recorder,
and a D/A Converter (to feed your monitors) are
connected to the OT-14 outputs. This setup allows the user
to take one mix output and simultaneously record to several
mixdown decks, saving hours of time and possible frustration.

To set up the OT-14 in your system, first make sure all of your
external devices are turned off. Then, using good-quality TOSlink
optical cables, follow this simple procedure:

1. With the OT-14 power button in the “out” (off) position, plug the
appropriate end of the supplied 9-Volt DC “wall-wart” power
adapter into your OT-14 and the other end into a wall socket or
power strip. The OT-14 power indicator LED should be off.

2. Take the output of your digital audio source device and plug it into
the OT-14 TOSlink input connector located on the rear of the OT-14.

3. Connect the OT-14’s TOSlink digital output connectors to the
inputs of your receiving or “target” digital audio devices. You may
want to connect the analog audio output of one of these devices
to a sound system for monitoring purposes.

4. With all volumes turned down, turn on your source device.

5. Turn on the OT-14 by pressing its power button and allowing it to
latch in the “in” position. The power indicator LED will light on the
front of the OT-14 unit.

6. Turn on your target devices. Your OT-14 is now ready for use.

NOTE: When any signal is present at the OT-14 input, the
“Signal Present” LED will light on the front of the unit. The
OT-14 is “format neutral” and does not analyze the incoming
signal. Therefore, although signal presence is detected by
the OT-14, it may not necessarily be a valid ADAT or S/PDIF
format signal.

Other Typical uses of the OT-14

• Sending a single digital out to multiple digital effects units.

• Outputting to several D/A converters simultaneously.

• Using a single digital out to both monitor your system’s
output and master to DAT and/or CD at the same time.

• Multiplying the sends on your digital mixer
