1073DPX

Twice the Neve Punch

The 1073DPX has two channels of 1073® Class A design microphone preamplifiers, each with 3-band EQ (fixed HF plus two switchable bands with cut/boost capability) and a high pass filter.

 

General Specification

  • 2 independent, genuine 1073® transformer-coupled microphone preamplifier/EQ circuits, in a single 2U 19″ rack-mount enclosure
  • Exclusive Neve® Marinair® transformers are used on each input and output stage.
  • Convenient connections for Mic, Line & DI inputs on the front of the unit, with switchable mic/line input connections on the rear of the unit
  • Switchable +48v Phantom Power, Hi/Lo impedance, -20dB pad and DI ground lift on the input stage
  • Switchable Phase, and EQ in/out
  • Insert send and return loop feature allows external equipment to be connected easily to the 1073DPX audio chain, such as mono/stereo limiter/compressors;
    • Pre-EQ insert send/return – a line level send is available from the mic-preamp output stage and a return just before the EQ stage
    • Post-EQ insert send/return – a line level send is available from the post-EQ stage and a return just before the main output stage
  • Independent channel output level controls
  • 7-stage LED signal level meters for each channel – can show mic/line/DI input-stage level, EQ-stage level or output-stage level up to +24dB
  • Headphone output with adjustable volume control can listen to channel 1, channel 2 or both channels combined
  • External multi-voltage PSU
  • Optional Digital I/O module
  • Power – 48Vdc, 480mA ±20mA excluding digital module. Negative Earth

Preamp Specification

  • Microphone Input: Gain +80db to +20dB in 5dB steps.
  • Line Input: Input impedance 10kΩ, gain +20dB to -10dB in 5dB steps
  • DI Input: Input impedance 10M Ohms (PAD off) / 10K Ohms (PAD on) Gain +80dB to +20dB in 5dB steps.

EQ Specification

  • High Frequency: Smooth +/-16dB fixed frequency shelving at 12kHz
  • Low Frequency: Smooth +/-16dB shelving with selectable frequencies of 35Hz, 60Hz, 110Hz & 220Hz
  • Mid Frequency: Smooth +/-18dB peaking, fi xed ‘Q’ with selectable centre frequencies of 0.36kHz, 0.7kHz 1.6kHz, 3.2kHz, 4.8kHz & 7.2kHz
  • High Pass Filter: 18dB per octave slope, switchable between 50Hz, 80Hz, 160Hz & 300Hz

Audio Performance

  • Output: Maximum output is >+26dBu into 600Ω, transformer balanced and earth free.  – Output Impedance 75Ω @1kHz
  • Distortion: Not more than 0.07% from 50Hz to 10kHz at +20dBu output (80kHz bandwidth) into 600Ω.
  • Freq Response: ±0.5dB 20Hz to 20kHz, -3dB at 40kHz. EQ Out.
  • Noise: -82dBu at all line gain settings (22Hz to 22kHz bandwidth)
  • EIN: Better than -125dBu @ 60dB gain.

Dimensions

  • Width: 480mm (19 inches)
  • Height: 88mm (3.5 inches)
  • Depth: 356mm (14 inches)
  • Approx. Weight: 10kg (22 pounds)
