Model PMA-300 300 Watt Central Amplifier

Speaker Out Connection

The amplifier's SPEAKER OUT connection uses a keyed, positive-locking Neutrik® SPEAKON

connector, which eliminates the possibility of vibrating loose. The 'keyed' feature prevents

misconnection to similar style connectors on the amplifier's rear panel. The amplifier contains a 70V out

and a 100V out connection depending on your constant voltage speaker system.

Notes:

•

Use only one of the SPEAKER OUT connections at a time.

•

If using the 100V out connection, only CLASS 1 wiring specification is acceptable.

•

If using the 70V out connection, CLASS 2 wiring specification is acceptable.

Connect the speakers as follows:

1. To properly terminate to the system speaker cable, use the enclosed SPEAKON™ connector (blue

body), which is supplied with the unit.

2. Determine which SPEAKER OUT voltage, 70.7V or 100V, is required for your constant voltage

speaker system.

3. Determine the desired wire gauge per the Speaker Wire Guidelines chart on page 6.

4. Determine the correct clamping strain relief depending on your cable's diameter.

5. For 100V Speaker Systems: Connect the audio (+) wire to pin 1 (+) and audio (-) wire to pin 1 (-)

(markings are embossed on body of connector) and tighten securely.

Note: Terminals 2 (+) and 2 (-) are not used. Refer to Figure 4 for connector location.

6. For 70.7V Speaker Systems: Connect the audio (+) wire to pin 2 (+) and audio (-) wire to pin 2 (-)

(markings are embossed on body of connector) and tighten securely.

Note: Terminals 1 (+) and 1 (-) are not used. Refer to Figure 4 for connector location.
