GML9500 
- Mastering Parametric Equalizer-

FORM FACTOR
Two channel, 5 fully parametric bands each with precision switched gain, frequency and Q
scaling;
• Frequency control per channel: 2 bands 13 Hz to 800 Hz, 1 band 130 Hz to 8 Khz, 2 bands
420 Hz to 26 Khz
• Gain adjustable to 0.5 dB resolution 0 to ±6dB, 1.0 dB resolution 0 to ±12 dB
• Q variable form 0.4 to 4 for all bands switchable to shelving on high and low bands

INPUT
20 kW balanced bridging
> 57 dB common mode rejection at 1 KHz
26.4 dBv maximum input before clipping

THROUGHPUT

Bandwidth:
0.1 dB down at <<10 Hz and 38 KHz
1 dB down at 150 KHz

Accuracy:
±0.10 dB 13 Hz to 26 kHz (gain multiplier switch in X1 position)
±0.15 dB 13 Hz to 26 kHz (gain multiplier switch in X2 position)
6% maximum frequency error

Harmonic Distortion:
0.001% typical 22 Hz to 22 kHz with EQ out
0.0015% typical 22 Hz to 22 kHz with EQ in
0.006% typical 22 Hz to 22 kHz with all bands switched in

Intermodulation Distortion:1
0.00100% typical at 20 dBv with EQ out
0.00100% typical at 20 dBv with EQ in
0.00450% typical at 20 dBv with all bands switched in

Noise:
-100 dBv typical with EQ out
-96 dBv typical with EQ in
-85 dBv typical with all bands switched in
Crosstalk between left and right channels:
-95 dB typical 22 Hz to 22 kHz at 20 dBv input with EQ out
-90 dB typical 22 Hz to 22 kHz at 20 dBv input with EQ in
-85 dB typical 22 Hz to 22 kHz at 20 dBv input with all bands switched in
