Operating Description
SCREW TYPE TERMINATION (front panel).
• On/off: short-circuit the MENU/GND terminations (see LED ST-
BY on the upper panel Fig. 2, p. 6).
• Led indicator connection: connect a led to the LED/GND
terminations ( Notice : respect the polarity).
• TRG OUTPUT: TRG OUTPUT: The CPA-60 has a +5V TRG output
capable of piloting other apparatuses. This voltage is between
the + 5V screw-type and GND terminations (200mA).
• Increase the volume: short-circuit the K1/GND terminations.
• Decrease the volume: short-circuit the K2/GND terminations.
• Connecting the left speaker: connect the speaker’s (+) and (–)
terminations to the L+/L- terminations ( Notice : respect the
polarity. Never attach speakers’ terminals to GND).
• Connecting the right speaker: connect the speaker’s (+) and (–)
terminations to the R+/R- terminations ( Notice : respect the
polarity. Never attach speakers’ terminals to GND).
TONE/BYPASS FUNCTION (upper panel): when the selector is
positioned on TONE, a fi nal amplifi er can be connected through
the double socket RCA OUT and its volume can be controlled
through the CPA-60.
In BYPASS position at the RCA OUT output, the same input sig-
nal will be present at the RCA INPUT, without any possibility of
controlling through the CPA – 60, whether it is on or off. Note: if
CPA-60 is not powered (LED POWER on), the RCA OUTPUT can-
not receive any signal.
GAIN ADJUSTMENT : with a screwdriver, with anti-clockwise
rotations, bring the GAIN screw control on the upper panel to a
minimum. Bring the CPA-60 volume to the maximum. Activate
the source. Rotate the GAIN screw control clockwise until the
sound emitted by the speakers becomes distorted. Now, slightly
rotate the screw control anti-clockwise until the sound is clear
of distortions; at this point, adjustment of the gain has termi-
nated.
