Epsilon Servo Control (Scu) Unit Connections - Infinity IRS Epsilon Owner's Manual

Epsilon
Epsilon Servo Control Unit (SCU) Connections
Regardless of the phase combination, always connect the woofer amplifiers as described below:
Woofer amplifier to Epsilon LOW PASS (woofer) terminals
Connect the "+" terminal of the left channel woofer amplifier to the red LOW PASS terminal of the left Epsilon (the
speaker to your left as you face them from the listening position). Connect the "-" terminal of the left channel woofer
amp to the white LOW PASS terminal of the left Epsilon. Repeat the connections for the right woofer amplifier and right
Epsilon.
The mid/high section amps connect in one of the two following ways:
Mid/High frequency with non-inverting amplifier, to Epsilon HIGH PASS (mid/high) terminals
Connect the "+" terminal of the left channel mid/high amplifier to the red HIGH PASS terminal of the left Epsilon.
Connect the "-" terminal of the left channel mid/high amp to the white HIGH PASS terminal of the left Epsilon. Repeat
the connections for the right mid/high amplifier and right Epsilon.
Mid/High frequency with inverting amplifier, to Epsilon HIGH PASS (mid/high) terminals
Connect the "+" terminal of the left channel mid/high amplifier to the white HIGH PASS terminal of the left Epsilon.
Connect the "-" terminal of the left channel mid/high amp to the red HIGH PASS terminal of the left Epsilon. Repeat the
connections for the right mid/high amplifier and right Epsilon.

CONNECTIONS
CAUTION: Turn off the AC power to all components
and switch the SCU to standby mode before making or
breaking any signal or power connections.
SCU AC power connections
The Epsilon SCU employs a power connection module
Figure 1.
that receives AC power from the wall via an "IEC" connector like
the ones found on virtually all computers and electronic
instrumentation. The module also contains the SCU's line fuse and a plug to select its operating voltage. Figure 1.
shows the details of the fuse mounting and the voltage selector. The SCU operates equally well on 5Ohz or 6OHz AC
power.
Voltage and fuse ratings
Before you connect the power cord to the SCU, please verify that the correct voltage for your power service shows
through the small window in the front of the fuse block. The table below shows the correct fuse rating for the various
voltage ratings. The SCU's AC voltage input can be set to one of four values: 100V, 120V, 220V, and 240V. If the
voltage rating is already correctly set, then the fuse rating probably is correct also. If not, then replace with correct fuse.
AC Line Voltage . . . . .Fuse rating . . . . . .Fuse type
100 or 120 . . . . . . . . . .500mA (1/2A) . . . . .FSF, 5x20mm (Bussman type GMC)
220 or 240 . . . . . . . . . .250mA (1/4A) . . . . .same as above
Changing the voltage selector or fuse
To change the voltage selector, or to check or replace the fuse, always unplug the power cord at the SCU before you access the
fuse and voltage selector. Insert the blade of a 1/8 (3mm) flat-blade screw driver into the small opening between the power cord
receptacle and the fuse block. Press the blade toward the fuse block to release the locking tab and pry out the fuse block.
