2.39Operation and Indicators Note that the Gain controls are calibrated in dB. As you turn the Gain down, it takes more input signal to reach full power, so the Gain should be kept in the upper 12 dB of its range for full power output from normal signal sources. The “0 dB” reference indicates that the amplifier gain is at 26 dB when the knob is adjusted to this position.
Note that full amplifier output power may be achieved even if the gain controls are not turned fully up. However, a larger input signal will be required to produce full rated output.
LED (Light Emitting Diode) indicators monitor the operation of the amplifier. A green LED serves as the pilot light to indicate that power is on. Each channel has a red “Clip” indicator that will show any distortion in the amplifier. Upon power up, these may not flash symmetrically. This does not necessarily indicate that there may be a problem.
