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.

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.
