APB-Dynasonics ProRack House H1020

Fantastic sounding analogue mixer.

• 12 Mono input channels and 4 Dual-Mono/Stereo 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, Mic/Line switch, Mic Pad switch, and Polarity Reverse switch.
• 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 and 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 bar graphs can meter 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, Mono, Groups 1-4, and Aux 1-6.
• 100-240 VAC, 50/60Hz Power Supply – Field replaceable (plug in) without disassembly of mixer. An adjustable lamp dimmer provided for the
• 4-Pin XLR connector for use with (optional) gooseneck lamp.
• Adjustable connector assembly rotates and can be locked into any of three different angles relative to the front panel.
• Direct Outs (can be internally configured pre EQ, post EQ or Post Fader)
