General Information; Connector And Cable Information - McIntosh C2600 Owner's Manual

General Information

1. For additional connection information, refer to the
owner's manual(s) for any component(s) connected
to the C2600 Tube Preamplifier.
2. The Main AC Power going to the C2600 and any
other McIntosh Component(s) should not be applied
until all the system components are connected
together. Failure to do so could result in malfunc-
tioning of some or all of the system's normal opera-
tions. When the C2600 and other McIntosh Com-
ponents are in their Standby Power Off Mode, the
Microprocessor's Circuitry inside each component
is active and communication is occurring between
them.
3. Balanced and Unbalanced Inputs and Outputs can
be mixed. For example, you may connect signal
sources to Unbalanced Inputs and send signals
from the Balanced Outputs. You can also use Bal-
anced and Unbalanced Outputs simultaneously,
connected to different Power Amplifiers.
4. The C2600 internal Digital to Analog Converter
Circuitry is designed to decode 2-channel PCM
(Pulse Code Modulation) and DSD (Direct Stream
Digital) Digital Signals. The Coaxial and Optical
Digital Audio Inputs are for PCM Digital Signals.
The Digital DIN and USB Audio Inputs are for
PCM and DSD Digital Signals. Other Digital Audio
Signal Format Types will cause the Audio Outputs
of the C2600 to be muted and the Front Panel Infor-
mation Display will indicate an error message.
5. Sound Intensity is measured in units called Deci-
bels and "dB" is the abbreviation.
6. The McIntosh C2600 is factory configured for im-
mediate use. It can also be customized to comple-
ment the components making up your system. Refer
to the C2600 "Setup Mode" starting on page 13 for
additional information.

7. The Remote Control Supplied with the C2600
Preamplifier is capable of operating other com-
ponents. For additional information go to www.
mcintoshlabs.com.
8. The IR Input, with a 3.5mm mini phone jack, is
configured for non-McIntosh IR sensors such as
a Xantech Model DL85K Kit. The signal from a
connected External IR Sensor will have priority
over the signal from the Front Panel IR Sensor.
9. When discarding the unit, comply with local rules
or regulations. Batteries should never be thrown
away or incinerated but disposed of in accordance
with the local regulations concerning battery
disposal.
