ProRack-House (H1020) Feature Overview:
|
-
20 Microphone pre-amplifiers in total. 12 Mono mic/line input channels and 4 Dual-Mono/Stereo mic/line input channels, all with Spectra-quality microphone preamplifiers in a 10u (17.5" in x 19") package.
-
Minimum phase shift circuitry and internal Mother Board/Daughter Board construction derived from the Spectra console design.
-
48 volt Phantom Power switch, Polarity Reverse switch, Mic/Line switch, Mic Pad switch on input channels. (Combo mic/line/pad switch on stereo input channels).
-
Variable frequency high-pass filters on all Mono and Stereo input channels with a 20Hz to 400Hz sweep range at 12dB per octave.
-
Mono input channels feature fixed high and low frequency EQ bands and two mid-sweep EQ bands, with EQ On switch with LED. The Stereo channels feature fixed high and low frequency EQ bands and a single mid-sweep EQ based on Spectra circuitry.
-
Six aux sends; each pair of sends switchable between a pre or post fader source. In the pre-fader position, an additional front panel switch determines if that pre-fader signal is derived pre or post EQ. Aux controls 5 and 6 may be switched to become a stereo pair.
-
All channels can assign to Left-Right, Center and Mono mix bus assignment along with additional assignment switches to subgroups 1-2 and 3-4. These outputs (including aux outputs) each have balanced XLR outputs, TRS bus inputs and TRS insert connectors.
-
Left-Right, Center and Mono mix output level can be switched from line level to mic level.
-
Internally illuminated Mute and PFL/AFL switches along with 6-segment LED channel metering and 100mm faders on all input channels.
-
Four LED meters can monitor the Left, Right, Center and Mono outputs or the Group 1-4 outputs. Meters auto-switch to show Solo levels.
-
Bus level signal monitoring using bi-color LED's on all 14 mix buses: Left, Right, Center, and Mono, Groups 1-4, and Aux 1-6.
-
100-240 VAC, 50/60Hz Power Supply - Field replaceable (plug in) without disassembly of mixer.
-
Rear panel rotates and may be locked in any of three preset angles (referenced to the front panel) - 90 degrees, 135 degrees, or 180 degrees.
-
Adjustable lamp dimmer provided for the 4-Pin XLR connector for use with (optional) gooseneck lamp.
