DIGITAL SYSTEM AMPLIFIER

2.10 Audio Cabling

Input

Inputs are electronically balanced. Whenever possible, using balanced audio signal feeds at the input of the power amplifier is always preferred. Unbalanced connections should only be used if the cables are very short and no interfering signals are to be expected in the vicinity of the power amplifier. In this case, bridging the screen (shielding) and the pin of the inverting input inside of the connector is mandatory. Otherwise, a 6 dB drop in level could result. Please also see following illustration. Due to their immunity against external interference sources, such as dimmers, mains connections, HF-control lines, etc., using balanced cabling and connections is always preferable.

Illustration 2.8: Balanced / unbalanced connection of input

Output in DUAL Mode or PARALLEL Mode

See illustration right for connecting speakers in DUAL or PARALLEL mode. Only connection of CH 1 and CH 2 is shown, the other channels have to be connected identically.

The correct connection is also indicated at the amplifiers rear panel.

Output in BRIDGED Mode

See illustration right for connecting speakers in BRIDGED mode. Only connection at CH 1/CH 2 is shown, the other channels have to be connected identically.

The correct connection is also indicated at the amplifiers rear panel.

CAUTION:

In BRIDGED mode operation, it is not allowable for the load connected to fall below the values given in table 2.2 on page 9. Extremely high voltages can be present at the output. The con- nected speaker systems must be able to handle such voltages. Make sure to completely read and fully observe power rating specifications of the speaker systems to be used and to check them against the output power capacity of the power amp.
