only briefly at the loudest peaks. The red LED is only triggered when the
input level is 4dB or less away from clipping the preamp's output. If the
red LED occasionally flashes while recording, it does not necessarily
mean that the preamp is clipping.
Note, however, that if you subsequently apply the CurveShaper's™ HF
boost, you may need to reduce the Mic Gain control correspondingly to
avoid system overload.
The Output Level control can apply up to +19dB of gain in the full
clockwise position, or it can attenuate the signal as much as -60dB just
like a fader on a console. Though the optimum position of the Output
Level control is unity at 0dB, the Output Level control may be used to
fine tune the overall output level.
Also remember, the energy and excitement generated during a
performance guarantees that it will always be louder than the rehearsal,
so after determining the gain during the sound-check it is a good idea to
set the Mic Gain control one or two clicks lower for the performance to
allow yet a little more margin for headroom.

Line and Direct Input Mode

When using Line or Direct Input mode, the Mic Gain control (ref. #10)
is bypassed. The Output Level control (ref. #11) allows you to control
the overall level of the Line and DI sources. The Output Level control
can apply up to +19dB of gain in the full clockwise position or can
attenuate the signal as much as -60dB just like a fader on a console.
If you subsequently apply HF boost, you may need to reduce the Output
Level control correspondingly to avoid system overload.

THE EQ SYSTEM

Using the LF Filter

The RPQ2 was designed to complement ribbon microphones. AEA
Big Ribbon™ mics deliver sub-woofer lows, which the RPQ2 renders
faithfully. Such strong low-frequency content can mask high-frequency
intelligibility, so the tunable low-frequency (LF) filter was engineered
to reduce low-frequency energy to appropriate levels. Directional
