+48V. The 48-volt phantom power, supplied by way of the XLR input, provides power
for condenser microphones and other devices requiring continuous power. This
power is supplied at a constant level to prevent any signal degradation.
WARNING: Phantom power is only required for condenser micro phones and
can severely damage dynamic mics, especially ribbon mics. Therefore, switch
phantom power off for all channels where it is not required.

Polarity Invert: Reverses the polarity of the signal.
Power User Tip: Use Polarity Invert when recording with more than one open microphone to
combat phase cancellation between microphones.
-20 dB Pad: The pad provides 20 dB of attenuation for the microphone preamp only.
Power User Tip: The 20 dB pad reduces the signal level coming into your ADL 600, helping to
prevent clipping and distortion from high-gain sources. Padding the input increases "headroom"
and reduces the likelihood of signal overload.
High Pass On/Off Switch: This switch bypasses or engages the High Pass Filter..
VU Meter: The analog VU meters display each channel's output level.
Meter: These eight-segment LED meters detect output-level peaks and fast
transients in each channel.
Meter -6 dB: This switch offsets the VU meters by 6 dB, which can help you meter
loud input sources if your VU meter is "slamming" or "pegged. "
