Certain specifications are presented here to assure the engineer that they are reasonable, to help plan the installation, and make certain comparisons with other processing equipment.
PERFORMANCE
Except as noted,
specifications apply for measurements from
the analog left/right input to the analog #1
and analog #2 output..
Frequency Response
(Bypass Mode): ±0.2 dB, 50 Hz - 9.5 kHz, or
as determined by user-settable high-pass and
low-pass filters.
Noise: Output noise floor
will depend upon how much gain the processor
is set for (Limit Drive, AGC Drive, Two-Band
Drive, and/or Multiband Drive), gating
level, equalization, noise reduction, etc.
The dynamic range of the A/D Converter,
which has a specified overload-to-noise
ratio of 110 dB, primarily governs it. The
dynamic range of the digital signal
processing is 144 dB.
Total System Distortion
(de-emphasized, 100% modulation): <0.01% THD,
20 Hz - 1 kHz, rising to <0.05% at 9.5 kHz.
<0.02% SMPTE IM Distortion. Polarity The
processing employs phase rotation to
maximize loudness. Therefore, the polarity
is frequency-dependent.
Processing Sample Rate: The
9300 is a "multirate" system, using internal
rates from 32 kHz to 128 kHz as appropriate
for the processing being performed. Audio
clippers operate at 128 kHz.
Processing Resolution:
Internal processing has 24 bit (fi xed
point) or higher resolution; uses Motorola
DSP56367 DSP chips.
Low-Pass Filter: 4.5, 5.0,
5.5, 6.0, 6.5, 7.0, 7.5, 8.0, 8.5, 9.0 or
9.5 (NRSC) kHz as set by user. Unit can be
set up to comply easily with ITU-R and NRSC
spectrum masks. Lowpass filter shape is
parametric and can be set to be -0.1, -3, or
-6 dB down at the cutoff frequency. This
allows you to trade off brightness against
audible filter ringing.
High-Pass Filter:
Constrained by user settable fifth-order
"quasi-elliptical" highpass filter to 50,
60, 70, 80, 90, or 100 Hz. All filters have
equal-ripple Chebychev-like) passbands and a
25 Hz notch for transmitter protection.
Channel Configuration:
Processing is monophonic.
INSTALLATION
Analog Audio Input
Configuration: Stereo
(Configurable to drive the processing with
mono from left, mono from right, or mono
from sum).
Impedance: >10 kΩ load
impedance, electronically balanced. (No
jumper selection available for 600 Ω.

module for user-installed 600 Ω
termination.)

A/D Conversion: 24 bit 128x
oversampled delta sigma converter with
linear-phase anti-aliasing filter. Converter
outputs 64 kHz sample rate, which the 9300
then decimates to 32 kHz in DSP using an
ultra-high-quality image-free synchronous
sample rate converter.
Filtering: RFI filtered,
with high-pass filter at 0.15 Hz (-3 dB).
Analog Audio Output
Configuration: Two
monophonic outputs, capable to driving two
transmitters. The two outputs have
independent level controls.
Source Impedance: 351 Ω
(includes the third-order output EMI
suppression network), electronically
balanced and floating. The user can specify
the output load in software to calibrate the
output level accurately into a bridging or
600 Ω load.
Load Impedance: 600 Ω or
greater, balanced or unbalanced. Termination
not required or recommended.

modulation)

unweighted (Bypass mode, de-emphasized, 20
