Operation

Power Switch

The POWER switch applies power to the unit. The switch will illuminate when power is on.

Individual Volume

Controls

Each input is controlled by an individual volume control.

The rear panel AX adjustment controls the mix of the Aphex effect with the audio signal. Counterclockwise rotation of the control minimizes the Aphex effect.

Clockwise rotation of the control maximizes the Aphex effect.

Dual Function Acoustic Equalizer

The unique dual-function equalizer can be used for acoustic shaping or for feedback control.

The overall volume is controlled by the

MASTER volume control.

Lo-Cut Filter

The Lo-Cut filter on the rear panel provides 3dB attenuation @ 65Hz on the microphone inputs. This helps reduce mic breath pop, wind noise, and rumble.

Contour Switch

This switch enables or bypasses the variable loudness contour.

This feature only effects the AUX inputs.

This feature is designed to improve richness of sound by restoring the high and low frequencies that the ear is insensitive to at low volume levels. The effect diminishes as volume is increased.

Aphex Aural Exciter

The front panel APHEX AURAL

EXCITER switch enables or bypasses the Aphex Aural

Exciter feature. This feature effects all inputs when enabled.

Note: When the switch is placed in the OUT position, the equalizer is bypassed for a flat response.

Acoustic Shaping Mode

When the switch is set in the ACOUSTIC EQ position, full range equalization (10 bands on 1 octave centers starting at 62.5Hz) is provided with a boost/cut of

12dB. In this mode, the equalizer can be used to compensate for room acoustics, or to satisfy the listening preference of the user.

Feedback Control Mode

When the switch is placed in the FEEDBACK CON-

TROL position, the equalizer can be used to reduce feedback and increase the effective gain of the system.

In feedback control mode, the equalizer provides increased control of frequencies between 125Hz and

8KHz. The 10 bands are located on 2/3 octave centers with 12dB cut/boost on each band.

By regenerating the upper harmonics, this audio enhancement system recreates the presence and realism that is lost in the audio amplification process. This results in increased presence and clarity, increased intelligibility, greater perceived loudness (without using extra power), and reduced listener fatigue.
