When you select any input, the Input LED associated with that input will glow. In addition, the Name
(
AUD1
,
AV4
, etc.) will appear for a moment in the Information Display window. These pre-programmed
Generic Names cannot be changed.
All analog inputs include sensitivity adjustments to avoid overloading and to equalize overall sound levels
as you switch from input to input.
Section 5.3.3
provides more details.

4.3.1.3
Input
Allocation
For example, you would use
AUD1
to connect a CD player with balanced (XLR) analog outputs because
AUD1
has XLR analog inputs only. Trying to use
AUD1
for a CD player with single-ended (RCA) analog
outputs only would be frustrating. Remember that the Digital input may be a better choice, as then you can
use the internal DACs of the SSP.
4.3.1.4
Channel Continuity
As you connect your components, make sure that a source’s left channel audio output goes to the
corresponding left channel audio input on the
SSP-25
-- and that the right channel output goes to the right
channel input, etc. (This is important for analog signal connections only as all digital audio signals, whether
stereo or multi-channel, carry “flags” that automatically allocate channel information precisely.)
4.3.1.5
Cable choices
Cables are an almost endless topic of debate among audiophiles and videophiles. Classé Audio does not
recommend any particular cable. However, we do point out that different connections require different
types
of cable. For example, normal analog audio interconnects are
not
ideal for either digital audio or video, but
will generally work in a pinch. Toslink requires an
optical cable
with special connectors on each end. No
other type of cable will work. S-Video cables also have no substitute, and great care must be taken when
plugging them in.
Coaxial digital
audio cables, those with RCA connectors at each end, should have an impedance of
75
ohms
.
Similarly,
video
cables, both composite and S-Video, should have a characteristic impedance of
75 ohms
.
