10 DC Trigger Input and Output
Many audio/video components can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
preamplifi er can take advantage of these capabilities in order to be switched
between operate and standby automatically, usually in concert with the A/V
preamp itself.
e 1/8th-inch mini mono-jack Trigger In provides for remote-controlled
turn-on (that is, toggling between operate and standby) of the preamplifi er.
Two 1/8th-inch mini mono-jacks provide individually controllable DC
trigger outputs which can be used for any of a number of purposes, as
described in e Menu System. For example, your dealer can program
Trigger Out1 to toggle your Classé power amplifi er between operate and
standby with your CP-700.
e remote trigger input will respond to the presence of 5–12VDC, with
tip polarity as shown below:
Similarly, the trigger outputs will create a 12VDC signal that can source up
to 100mA of current.
11 Ground terminal
e ground terminal on your preamplifi er is most often used for the
ground wire of a turntable, assuming you have the optional phono module
installed (see your authorized Classé dealer for more information on this
option if you are interested). Connecting the ground wire from your
turntable’s tonearm to this screw terminal usually minimizes any hum
or buzzing to which the turntable might otherwise be susceptible. Your
authorized Classé dealer can assist you in handling this problem if it should
arise.
12 DC Power Input
e DC Power Input for the CP-700 is located near the middle of the
rear panel. Connect the provided multi-pin “umbilical cord” between the
outboard power supply and this connector to provide the preamplifi er with
the clean, pure DC power it needs to do its job.
ere is also an AC mains switch on the back of the outboard power
supply. Switching the power supply on (assuming the preamplifi er is
connected with the umbilical cord) puts the preamplifi er in standby mode.
e preamplifi er should also be in standby before power is switched off .
Danger! Potentially dangerous voltages and current capabilities
exist within your power supply, even when disconnected
from AC mains. Do not attempt to open any portion of the
unit’s cabinet. There are no user-serviceable parts inside.
All service of this product must be referred to a qualified
authorized Classé dealer or distributor.
