X-Rack Mic Amp Module

A.3 Performance Specification

The following pages contain audio performance specification figures for the X-Rack Mic Amp module. No other Solid State Logic products are covered by this document and the performance of other Solid State Logic products can not be inferred from the data contained herein.

A.3.1 Measurement Conditions

For each set of figures on the following pages, the specific unit and test setup will be stated at the beginning of that section. Any changes to the specified setup for any particular figure(s) will be detailed beside the figures to which that difference applies.

A.3.2 Measurement References

Unless otherwise specified the references used in this specification are as follows:

•

Reference frequency:

1kHz

•

Reference level:

0dBu, where 0dBu ≈0.775V into any load

• Source impedance of Test Set:

50Ω

• Input impedance of Test Set:

100kΩ

•All unweighted measurements are specified as 22Hz to 22kHz band limited RMS and are expressed in units of dBu

•All distortion measurements are specified with a 36dB/Octave low pass filter at 80kHz and are expressed as a percentage

•The onset of clipping (for headroom measurements) should be taken as 1% THD

•Unless otherwise quoted all figures have a tolerance of ±0.5dB or 5%

•All measurements are made with the operating level switch set for +4dBu

A.3.3 Microphone Amplifier Performance

Signal applied to Microphone Input and measured at Output. Pad switched out and Input Gain control set to +12dB (minimum).

Gain

Continously variable from +12dB to +75dB

 

Independently switchable 20dB Pad available

Input Impedance

Continously variable from ≈1k2Ω to ≈10kΩ

Output Headroom

> +26dBu at onset of clipping

THD + Noise

< 0.003% at 1kHz

(-18dBu applied, +28dB gain)

< 0.006% at 10kHz

Frequency Response

+0.05dB/-0.1dB from 20Hz to 20kHz

 

–3dB at 150kHz

Equivalent Input Noise

< –127dB at maximum gain

(input terminated with 150Ω )

< –90dB at 0dB gain (+20dB with Pad ‘IN’)

Common Mode Rejection

> 75dB from 50Hz to 1kHz

(-10dBu applied, +30dB gain)

> 70dB at 10kHz
