TOA Electronics TA 1400 Rear Panel, Clip/limit indicator, Signal present indicator, On indicator

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.
