3. Clip/limit indicator

This indicator signals when the amplifier output is clipping or limiting. It has two different indication states:

If the clip limiter is engaged, it has a short time constant and it illuminates briefly. (See page 13). If the clip limiter is not engaged, it has an increased time constant and it illuminates for a longer period.

4. Signal present indicator.

Illuminates at –40dB below full output signal.

5. On indicator

The two bottom green ”ON” LEDs indicate that the output circuits are receiving the correct rail voltage.

6. Power switch

Turns mains power on or off. (See page 9 and 12)

7. Fan grill filters

A grille with foam filters is located on the front panel to prevent dust from entering the amplifier. The grille is removable for easy cleaning of the filter by simply pulling them off. The foam filter should always be used.

8. Carry/protection handle

Both handles can be used to carry the amplifier; they also act as protection for the front panel. In fixed installations or where rack front covers are too shallow, they may be removed by unscrewing the retaining bolts behind the front panel.

The Speakon connector from Neutrik® may be unfamiliar to some users. A full description is found in the operation section. (See page 12).

3. Clip limiter switch

Turns the clip limiter on (switch IN position) or off (switch OUT position). (See page 13).

4.Input signal XLR. Neutrik® Combojack features also ¼” TRS phone jacks. (Pin 2 is “hot”, see page 10).

5.Link Output. 3-pole screw terminal of Phoenix brand. Connected in parallel to the female XLR input connector for linking the channel to another input.

6.Gain switch channel B. Three of the switches in the DIP-switch selects the maximum gain of the channel to be either 20, 23, 26, 29, 32, 36, 39 or 41 dB. (See page 6).

7.Link and Polarity reverse switch. Two of the switches in the DIP-switch are used for Link and Bridge operation. (See page 6).
