1.
Routing: Matrix Input source selection for specific Output channel. Can be InA, InB, or InA+InB.
2.
High and Low Pass Filter: Selection of High Pass and Low Pass crossover Filters on each Output channel.
2A.
Frequency: The center frequency for all filter types range from 20 – 20K Hz.
2B.
Slope/Type: Available filter Types and Slopes are as follows:
Butterworth - 6, 12, 18, 24, 36, 48 dB/Oct
Linkwitz Riley - 12, 24, 36, 48 dB/Oct
Bessel - 12, 24 dB/Oct
By-Pass - Allows to bypass HP/LP feature.
3.
EQ Filters: 7 bands of selectable parametric EQ. The following filter types are available:
3A.
Bell – Peak type filters, with adjustable Center Frequency (20 to 20k Hz), Bandwidth (0.4 to 128 Q),
and Gain (-15 to +15 dBV).
Hi/Lo Shelving – Variable Shelving filters with adjustable Center Frequency (20 to 20k Hz), Bandwidth
(0.1 to 5.1 Q), and Gain (-15 to +15 dBV).
Hi/Lo Pass – Variable Hi and Lo Pass filters with adjustable Center Frequency (20 to 20k Hz), and
Bandwidth (0.1 to 5.1 Q).
Notch – Variable Notch Filters with adjustable Center Frequency (20 to 20k Hz), and Bandwidth
(4 to 104 Q).
3B.
Byp – Bypass for each particular Filter.
3C.
Cursor – Pressing the Cursor button turns on the drag and drop EQ points on the graphical view.
3D.

4.
Peak Limiter: a Peak Limiter is available on the Outputs. It can be used to limit the maximum output
voltage. The following parameters are available:
4A.
Thr – Peak Limiter Threshold, ranging from 6 to 97 Vrms for AmpA/B and -18 to 12 dBV for Line Output
Release – Time to stop limiting, once below threshold, ranging from 100ms up to 5Sec.
Attack – Time to start limiting, once above threshold, ranging from 1ms up to 900ms.
4B.
Gain Reduction – Displays the gain reduction due to Peak Limiter.
4C.
Bypass – Check box allowing to bypass the Peak Limiter feature.
