Introduction
The AirTools 6200 Digital Voice Processor is designed to meet the increasingly sophisticated needs of broadcasters operating
in both analog and digital realms featuring an optimum mix of signal processing modules and control features. The modules
include: highpass, lowpass, and shelving filters, de-esser, downward expander, comp-limiter/AGC-leveler, 4-band parametric
EQ and voice symmetry. The 6200 is a dual-channel unit with two discrete audio pathways capable of processing microphone
or line-level sources, independently or as a stereo pair with a 24-bit/48kHz digital signal path. Creation of voice programs
and signal processing parameters may be done from the 6200 front panel or from 6200 Designer, a Windows™ application
(provided). From a PC, the 6200 may be controlled via RS-232, USB or Ethernet. In lieu of computer control, real time changes
of program and DSP parameters may be actuated via user supplied ESE time code, pots, encoders, switches, or MIDI devices.
The 6200 is also compatible with the AirTools Studio Matrix system which can mix, process, and route audio throughout an
entire broadcast facility. The 6200 can be connected to and from the Studio Matrix system via HomerLink, a low cost Symetrix
technology that transports AES digital audio over CAT-5 cable for distances up to 100 meters. CAT-5 can also be used to
connect a 6200 to a distant HomerLink Breakout box converting to standard AES-3 XLR connectors.

Remarks
Space Required 1U (WDH: 48.26 cm x 26.6 cm x 4.369 cm /
19 in x 10.475 in x 1.72 in). Depth does not
include connector allowance.
Allow at least 1 inch additional clearance for rear panel con-
nections. Additional depth may be required depending upon
your specific wiring and connections.
Electrical
100-240 VAC, 50-60 Hz, 25 Watts maximum. No line voltage switching required.
Ventilation
Maximum recommended ambient operating
temperature is 30 C / 86 F.
Ventilation should not be impeded by covering the unit with
items such as newspapers, tablecloths, curtains, etc.
Weight
4.45 kg / 9.82 lbs.
Performance Data
Inputs
Nominal Input Level
Analog: +4 dBu or -10 dBV line level, -36 dBu or -56 dBu
mic level (software selectable) with 20 dB of headroom
Digital: -20 dBFS
NOTE: For unbalanced analog
input, either reference the minus
input terminal to the signal source
ground (preferred) or ground the
minus input to the adjacent ground
terminal (tie low to ground). Using
the second method deprives you of
the common mode rejection inher-
ent in a balanced input, even when
coming from an unbalanced source.
Maximum Input Level
Analog: +24 dBu
Digital: 0 dBFS
Input Impedance
Analog: 20k Ohms
Digital: 110 Ohms, +/- 10%
CMRR
Analog: > 50 dB (0 dBu, 20 Hz to 20 kHz)
Analog to Digital Conversion 24-bit delta/sigma
Outputs
Nominal Output Level
Analog: +4 dBu line level with 20 dB of headroom
Digital: -20 dBFS
NOTE: For unbalanced analog
output, float (do not connect)
the minus output terminal.
Unbalanced usage results in 6
dB lower output level.
Maximum Output Level
Analog: +24 dBu
Digital: 0 dBFS
Output Impedance
Analog: 200 Ohms balanced, 100 Ohms unbalanced
Digital: 110 Ohms, +/- 10%
Digital to Analog Conversion 24-bit delta/sigma
System
Nominal Sample Rate
48 kHz
Sample Sync Range
48 kHz +/- 100 ppm (AES-3 or AES-11 via HomerLink)
Dynamic Range
Analog: > 114 dB (20 Hz to 20 kHz, A-weighted)
Digital: 144 dB typical, unweighted
Frequency Response
Analog: 20 Hz - 20 kHz
Digital: 20 Hz - 24 kHz
THD + Noise
Analog In-to-Out: 0.0035% (20 Hz to 20 kHz, unweighted with +24 dBu output)
Digital In-to-Out: > 117 dB @ 1 kHz
