The C48 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 (XRL Connector).
Notes: 1. Any one of the Default Inputs may be swiched
Off. If any input is switched Off its name will
no longer appear on the Front Panel Informa-
tion Display when using the INPUT Control,
nor is it accessible with the Remote Control.
2. The Phono MC (Moving Coil) and MM (Mov-
ing Magnet) Input are designed for connection
of a turntable only and thus non-reassignable.
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.
