PERFORMANCE

Input EQ:
6 parametric filters per channel with adjustable Q, ±15 dB boost/cut. Also adjustable high and low shelving filters. This 8-filter EQ section can be bypassed.

Crossover Filters:
Highpass and Lowpass per channel. Butterworth 6/12/18/24 dB per octave. Linkwitz-Riley 24/48 dB per Octave. Also includes ± 15 dB bandpass gain and polarity control

Output EQ:
8 parametric filters per channel with adjustable Q, ±15 dB boost/cut. This 8-filter EQ section can be bypassed.

Delay:
For signal alignment of driver; 50 mS of total delay.

SubHarmonic Synth:
Takes the low-frequency content of the input signal and "synthesizes" a new signal that is the same as the input signal but one octave lower. The new synthesized signal is then mixed with the original signal to create the effect. New: Users now have control over frequency, gain, and filter type.

Peakx Plus Limiter:
User defeatable limiter that allows users to control Threshold, Attack, and Release times.

Presets:
30 total presets, 29 of which are user-definable.

Frequency Response (at 1 watt, 20 Hz - 20 kHz):
+0 dB, -1 dB

Signal-to-Noise Ratio (below rated 1kHz power at 8 ohms):
100 dB (A weighted)

Total Harmonic Distortion (THD):

• Damping Factor 20 Hz to 1 kHz
• Crosstalk (below rated power)
• 20 kHz - 1 kHz: > 70 db
• Input Impedance (nominal)

• LCD Screen
• Backlit liquid crystal display that shows preset and processing status

INDICATORS

Signal Indicator:
Green LED, one per channel, illuminates when a very low-level signal is present at input (may be used for troubleshooting cable runs).

• 10 Indicator:

Green LED flashes when output signal exceeds -10 dB below clip.

• 20 Indicator:

Green LED flashes when output signal level exceeds -20 dB below clip.

Ready Indicator:
Green LED, one per channel, illuminates when the amplifier is ready to produce audio.

Clip Indicator:
Red LED, one per channel, turns on at the threshold of audible distortion

Temp Indicator:
Red LED, one per channel, illuminates under excessive temperature conditions

Power Indicator:
Blue LED illuminates when the amplifier has been turned on and has power

CONNECTORS

Input Connectors:

• XLR, one per channel
• Link/Out Connector
• Loop-thru signal from input connector for linking another amplifier, one per channel.

Output Connectors:
