Specifications - Harrison 950mx Overview

10.0 Specifications

AUDIO SPECIFICATIONS
The following specifications apply to Harrison 950mx consoles and are subject to change without notice. Harrison 950mx
consoles will be tested to meet only those specifications in effect at the time of final testing. These specifications represent
an overall system and not the individual components of a system. They represent the cumulative effect of all components.
Additionally, these specifications are stated over a wide range of operating conditions representative of actual use conditions
rather than a restrictive set of conditions likely to be seen only when conducting systems tests. Therefore, these
specifications represent the worse case in-use conditions rather than test conditions developed for competitive advantage.

Logic Returns Pull to ground, nominally pulled up internally via a 10 kOhm resistor
Logic Feeds Open collector, will sink up to 50 V @300mA. Fully protected
Crosstalk Amplitude >80dB (Line In to Mix Bus Out +24 Out @15K)
Frequency Response
Microphone input to Mix Bus line output. Conditions are: input source impedance of 150 to 200 Ohms, output load
impedance of 600 Ohms, channel fader and Mix Bus fader set for unity gain, effective measuring bandwidth of 20 Hz to 20
kHz. Gain shall not deviate from gain at 1kHz for any frequency from 20 Hz to 20 kHz more than +.2dB to -2dB.
Line input to line output. Conditions are: input source impedance of 600 Ohms, output load impedance of 600 Ohms,
channel fader and Mix Bus fader set for unity gain, effective measuring bandwidth of 20 Hz to 20 kHz, and overall gain of
unity. Gain shall not deviate from gain at 1 kHz for any frequency from 20 Hz to 20 kHz by more than +.2dB to -1.0dB.
Noise
Microphone in to Mix Bus line out.
Conditions are: input source impedance of 150 to 200 Ohms, output load impedance of 600 Ohms, channel fader and Mix
Bus fader set for unity gain, one input module is assigned to the Mix Bus output, effective measuring bandwidth of 20 Hz to
20kHz, meter response unweighed to DIN 45 405 and DIN 45 500, meter ballistics true RMS to DIN 45 402 and DIN 45 500,
overall gain is 70 dB at 1 kHz. The equivalent input noise shall not exceed -129dB (ref: 0.775 VRMS). Keeping all the test
conditions the same with the exception that the overall gain is 38dB and the quantity of channels assigned to the output is
four, the noise measured at the output shall not exceed -70dB (ref: 0.775 VRMS). Keeping all the test conditions the same
with the exception that no input channels are assigned to the output, the noise measured at the output shall not exceed -80
(ref: 0.775 VRMS).
