1. The C2300 uses Vacuum Tubes for amplifying the
audio signal. The C2300 is designed to have only
qualified Service Personnel perform any part(s)
replacement including all the vacuum tubes.
2. For additional connection information, refer to the
owner’s manual(s) for any component(s) connected
to the C2300 Tube Preamplifier.
3. The Main AC Power going to the C2300 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 C2300 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.
4. Up to two Sensors can be wired in parallel for Re-
mote Control of the C2300 from other rooms.
5. 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.
6. The Remote Control Supplied with the C2300 Tube
Preamplifier is capable of operating other com-
ponents. For additional information go to www.
mcintoshlabs.com.
7. 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.
