REAR PANEL

INPUT A / INPUT B

The inputs INPUT A & INPUT B are electronically balanced offering input sensitivity of +5.8dBu (1.51V) for direct connection of mixing consoles, signal processors, etc.

The XLR-type connectors OUTPUT A & OUTPUT B are pre- pared for „through-connecting“ input signals to additional ex- ternal power amps. The input signal is directly routed to these output connectors. There are no repeaters or other electronic

components within that signal path. Accordingly, input and output connectors of the corresponding channel are interconnected in parallel, offering permanent electrical connection, without regard to the setting of the Power-ON switch.

Although having XLR-type output connectors, some mixing console models provide unbalanced output connection only. When using mixers with unbalanced outputs, bridging PIN1 and PIN3 of the power amp’s input connectors or leaving PIN3 of the cable’s plugs unconnected is necessary. Otherwise, when feeding in unbalanced audio signals via PIN3 (b, -, „cold“) and PIN2 (a, +, „hot“), strange humming and HF-interference may occur, which very likely will damage the power amplifier and/or the connected speaker cabinets.

NF-CONNECTION CORDS

Choosing high-quality balanced cables (two conductors for the audio signal plus separate shielding mesh) with XLR-type connectors is recommended for LF-signal connection. Although connecting un- balanced cables to the power amplifier inputs is possible as well, using balanced cables is always pref- erable. A great number of today’s audio appliances employ balanced outputs. With balanced cabling, the shield connects all metal enclosure parts and therefore efficiently eliminates the introduction of external interference – mostly noise and hum.

PARALLEL

The input connectors of channel A and channel B are electrically connected in parallel when the selector switch is set to PARALLEL. However, individually controlling the volume of both channels is still possible via the corresponding level controls A and B.

DUAL

If the selector switch is set to DUAL, the audio signals of channels A and B are independently amplified.
