6 DC Trigger Input and Output
Many audio/video preamplifiers can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
amplifier can take advantage of these capabilities in order to be switched
between operate and standby automatically, perhaps in concert with the
A/V preamp itself.
Two / -inch mini mono-jacks provide this remote-controlled turn-on
1 th
8
(that is, toggling between operate and standby) of the amplifier. These jacks
provide a simple pass-through of the control voltage from one to the other,
allowing you to "daisy-chain" a series of amplifiers quite easily.
The remote trigger will be operated by the presence of 5–12 Volts DC,
with tip polarity as shown below:
7 RS 232 Control Port
This DB-9 connector has two purposes:
• downloading new operating software into your amplifier (should
new features ever be added, for example)
• for external control of your amplifier by systems such as
AMX , Crestron
®
For more information, please contact your dealer and ask about home
automation systems.
8 USB Control Port
The USB connector provides the same functionality as the DB-9 connector
described above. It is compatible with the USB ports on PCs and may
obviate the need for a USB to RS-232 adaptor.
9 AC Mains Input
An IEC standard power cord (supplied) is used with the CA-2300/CT-
2300. Plug the cord into the IEC receptacle on the rear panel, and the
other end into a suitable wall outlet.
10 AC Mains Fuse
Your Classé power amplifier has an AC mains fuse, accessible on the
rear panel. If you suspect that your AC fuse has blown, disconnect your
amplifier from the AC mains, as well as from its input connections and
speaker connections, and refer to the appropriate item of the section
enitled Troubleshooting.
