2. Protect indicator LED

This indicator illuminates if the amplifier attempts to function above its maximum operating temperature (90°C). The indicator first comes on as a warning, to either turn down the input level or check the cooling arrangements, after which point the amplifier will mute the input signal. When the cooling fans have returned the output heat sinks back to the normal operating temperature the input signal is un-muted. This indicator also illuminates when signals above 12 kHz at full power are detected at the output terminals or if the short circuit protection is activated. Should this occur the input signal is muted, and the process repeats until the VHF signal is no longer present or the short circuit is removed. (See page 15).

3. Clip/limit indicator

This indicator signals when the amplifier output is clipping or limiting. It has two different indication states: When the clip limiter is engaged, it has a short time constant and it illuminates briefly. (See page 15). When the clip limiter is not engaged, it has an increased time constant and it illuminates for a longer period.

4. Signal present indicator

This LED Illuminates at –40dB below full output signal.

5. On indicator

The four bottom green ”ON” LED's indicate that the output circuits are receiving the correct rail voltage.

6. Power switch

Turns the mains power “ON” or “OFF”. (See page 9 and12)

7. Fan grille 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.
