Firmware Version; Reassign Source Inputs - McIntosh C2500 Owner's Manual

Firmware Version

The C2500 functionality is controlled by internal soft-
ware that is know as Firmware. The C2500 has two
different Firmwares, one is the "System Firmware"
(responsible for the basic operation of the C2500) and
the other known as USB Audio Firmware (responsible
for the "USB Connection and Conversion" of a Digital
Audio Signal from the Computer). The Version of the
Firmwares in the C2500 can be identified at any time
by utilizing the Setup Mode.
1. Press and hold the TONE BYPASS/SETUP Push-
button until the Front Panel Display indicates
"C2500 V_.__, S/N: _______". The number after
the "V" is the firmware version and the number
after the "S/N" is the serial number of the unit.
Refer to figure 2A.

Reassign Source Inputs

The C2500 provides the ability to reassign the non-
Phono Inputs (High Level) to either one of two Bal-
anced Inputs or one of the four Digital Inputs.
In the first example, the CD2 Input will be reassigned
from the unbalanced CD2 (RCA Jacks) to the BAL-
ANCED 1 (XLR Connector).
Notes: 1. Any one of the Default Inputs may be switched
Off. If any input is switched Off, its name will
no longer appear on the Front Panel Display
when using the INPUT Control, nor is it acces-
sible with the Remote Control.
2. The Phono MC (Moving Coil) and MM (Mov-
ing Magnet) Inputs are designed for connec-
tion of a turntable only and thus non-reas-
signable. However, the Phono Inputs may be
switched Off.
3. Only one Input may be assigned at a time to a
Balanced (1 & 2) or Digital (1 thru 4) Connec-
tor. If an already assigned Balanced or Digital
connector is to be reassigned to a different
Input, the Input currently assigned to the con-
nector first needs to be changed. It can be set
to a RCA connector or to another available
Balanced or Digital connector.
1. Press and hold the TONE BYPASS/SETUP Push-
button until the Setup Mode is active. Then press
the OUTPUT 2 / MENU ► Push-button to select
the Setup Menu item "SETUP: SOURCE INPUT,
TUNER :RCA". Refer to figure 4.
