Caution!
ST DIGITAL INPUT
This input accepts digital audio conforming to the ST optical (sometimes
called "AT&T"—ST is a trademark of AT&T and the correct designation for
the interface) digital interface standard from the ST digital output of a digi-
tal FM tuner, compact disc player, laserdisc player, or digital audio recorder.
Connect the digital output of your digital source component to the ST input
of the DAP using a high quality optical cable.
REMOTE IR
A 1 ⁄ " (3.5 mm) "mini" jack in the lower right corner of the rear panel pro-
8
vides direct access to the infrared control circuitry of the DAP . This
input facilitates a wide range of installation options. If desired, the DAP
IR
may be placed inside a cabinet or outside the normal line-of-sight in the
listening area, with the controlling IR signal being relayed to the DAP by
any of a number of commercially-available IR repeaters.
The incoming signal for the remote IR input should conform to widely-ac-
cepted IR repeater standards: that is, the signal present should be between
3-12 volts DC at less than 100 mA current, with a positive tip polarity, as
shown below:
Y our Proceed dealer can help you take advantage of these design features
to maximize your system's versatility . (Note that the DAP is not supplied with
an infrared remote control. Instead, it can teach a learning remote such as
those provided with Proceed preamplifiers the needed commands, reducing
the overpopulation of remote controls on your coffee table by one. See "Re-
mote Control of the DAP" for more information.)
AC MAINS FUSE AND AC POWER RECEPTACLE
An ac mains fuse is provided which disconnects the DAP from the wall
outlet's AC power under fault conditions. If this fuse should "blow" for any
reason, replace it only with the same value fuse (0.5A/250V slo-blo
5x20mm). If it blows a second time, please contact your Proceed dealer for
service.
Replacing the ac mains fuse with a anything other than the
recommended value fuse will places the DAP at substantial
risk of damage!
Plug the supplied three-prong power cord into the
tacle provided before plugging the power cord into the wall. If a longer AC
power cord is required for your application, be sure to use a three-conduc-
tor power cord which conforms to IEC standards.
