DA2 Expansion Slot
The C8 has an expansion slot to allow for the
installation of the DA2 Digital Audio Module. The
DA2 will add the following digital audio inputs:
•
two coax
•
two optical
•
one HDMI (ARC)
•
one MCT
•
one USB audio
Due to the technical nature of the DA2 upgrade,
the upgrade must be performed by a qualified
trained professional at an Authorized McIntosh
Dealer or Authorized McIntosh Service Agency.
Please note that if the upgrade is performed by
anyone other than an Authorized McIntosh Dealer
or Authorized McIntosh Service Agency, under
the terms of your McIntosh Limited Warranty any
resulting damage or failure of your unit will be
excluded from warranty coverage. Contact your
local Authorized McIntosh Dealer or Authorized
McIntosh Service Agency to schedule your upgrade
if you wish to add digital capabilities to your C8.
AC Power
This connection is essential. Plug the female end of
the supplied AC Power Cord into the AC connector
(standard 15 ampere IEC) located in the rear right
corner of the C8. Plug the male end of the AC
Power Cord into a grounded and functioning AC
outlet.
Power Control (Trigger) Outputs
The C8 has three Power Control Outputs or
Triggers:
•
MAIN
•
TRIG 1
•
TRIG 2
Power Control enables power on/off signals to go to
connected components so that other components can
automatically powered on (or off) as called for by
the C8.
Connect components to the Triggers using a 3.5mm
stereo mini plug. see Figure 10. The Triggers work
by sending on/off signals in the form of +12 volt/0
volt to connected McIntosh components.

Passthru
The C8's PASSTHRU feature allows your
2-channel system to be incorporated into a
multichannel system, typically as the left and right
front speakers. When the connected unit (Master)
powers on, it will take control of your C8. The C8
will send the signal to your amplifier and speakers
at a volume controlled by the Master. The C8
preamplifier is now a slave to the source unit and
you cannot control the sound from this unit until the
source unit is shutoff or disconnected.
To use the PASSTHRU feature, connect the
controlling unit to the C8's PASSTHRU connector
using the same type of cable as used for Power
Control (Trigger) Outputs. The C8 PASSTHRU jack
should be connected to a Power Control Trigger
Output of the controlling unit.
To enable (or disable) PASSTHRU, enter Setup.
When enabled, an Input must be assigned to
PASSTHRU. When in PASSTHRU mode, the C8
will send the signal from the assigned Input to the
C8's Outputs. The volume will be dictated by the
controlling unit.
To turn off or assign an Input for PASSTHRU:
•
Press and Hold the Left Knob for two seconds
•
Turn the Left Knob to the menu choice
"SETUP: PASSTHRU"
•
Turn the Right Knob to scroll through the
following options:
•
Off
•
Balanced
•
Unbal 1
•
Unbal 2
(Note: if you have changed an Input's
name, the new name will appear.)
•
Press and release the Left Knob to exit Setup.
Your choice will be saved
When in PASSTHRU mode, control of the
C8 is limited to the Trim functions: DISPLAY
BRIGHTNESS and AMP METER LIGHT. To
regain controls, the Controlling unit must be shut (or
Power Control cable removed from the PASSTHRU
connector.)
Data Out
The C8 will convert IR Remote Control data to
share with McIntosh components connected to the
DATA PORTS. This will allow units that are out
of range of an IR signal to receive commands. A
McIntosh source can thereby be controlled by the
C8 Remote.
