A. INPUT LEVEL CONTROL - Variable attenuator controls the amplifier's input sensitivity. Control settings can vary between +8dB (fully up) and infinite attenuation (fully down). At the full up position, a 360mV input signal is required for rated output. At 0, a 360mV input signal will yield an output power of 1/8th rated power.

B. NOTCH FREQUENCY CONTROL - Higher notch frequencies are selected as the knobs are rotated in the clockwise direction. Each knob covers a specified frequency range, but two adjacent knobs do have overlapped frequencies. This feature is intentional. Refer to the "Hints and Precautions" found on page 7 for details concerning this feature.

C. NOTCH DEPTH CONTROL - These sliders provide attenuation control for each notch filter frequency band. At the highest position, 0dB of attenuation is obtained. At the lowest position, they can provide more than 25 dB of attenuation at the selected frequency. Refer to the "Hints and Precautions" found on page 7 for details concerning this feature.

D. HIGH FREQUENCY ROLL OFF CONTROL (LOW PASS FILTER) - Useful for smoothing out "edgy" sounding speakers. When this knob is fully in its clockwise position, all signals below 30 kHz are allowed to enter the power amplifier. If set fully counter clockwise, only signals below 2.5 kHz will be

permitted to pass through. Start with this control set at 30 kHz. If the performers complain of "edgy" sounding monitors and want smoother sounding ones, rotate this control counter clockwise until they are pleased with the sound.

E. LOW FREQUENCY ROLL OFF CONTROL (HIGH PASS FILTER) - Useful for removing rumble (mechanical noise) or resonance and L.F. leakage. When this knob is fully in its counter clockwise position, all input signals above 12Hz are allowed to pass. When it is positioned fully clockwise, only frequencies above 150 Hz are permitted to enter the power amplifier. Start with this control set at 12 Hz. If the performers want crisper sounding sounding monitors slowly rotate this control clockwise until they are pleased with the sound.

F. POWER LED INDICATOR - LED is illuminated when the monitor amplifier is turned on, and the AC mains voltage is present. If the indicator does not light when the power switch is turned on (and does not trip the circuit breaker), check the AC power supply and fuse.

G. DELTACOMP™ SWITCH - This switch activates the internal compressor circuit. Peak clipping is minimized when the compressor circuit is active. This will also "clamp" feedback, helping protect your monitor speakers. During normal operation, keep this switch engaged.
