Voice Processor 2x
Next generation two channel programmable Voice Processor for today’s broadcast professional.
The microphone is a crucial link to the audience.
Proper management of that link is essential.
Enter the Voice Processor 2x, an outstanding
programmable microphone processor that is flexible,
powerful, and easy to use.
Chief Engineers treasure its programmability and
rich DSP feature set. On-air talent enjoy its simplicity
of operation. Studio managers appreciate how it
independently processes two microphone channels
in one rack space. And, most importantly, everyone
loves the sound – including the listening audience.
The 2x offers a comprehensive set of voice
enhancement tools for any situation. The 2x’s
Windows® software application enables total control
of all essential parameters. Once a desired sound is
dialed in, all settings are saved as named presets for
later recall from the front panel or remotely. Any mic
can be optimized for a diverse air staff with either
male or female voices.

Our Voice Processor legacy began with the original
model 528, and has continued through the 601,
528E, 628 and 6200. Now you can maintain quality
assurance throughout your voice talent signal chains
with the Voice Processor 2x, Engineered by Symetrix.
Our name has become synonymous with high quality
audio processing for over 40 years.
• Two (2) independently programmable
channels of ultra-low latency digital
microphone processing in one rack space.
• Two (2) Mic/Line inputs, two (2) Mic/Line
outputs, two (2) AES3 outputs, Word
Clock input.
• Processing modules include Compression,
Equalization, De-Essing, Downward
Expansion, Highpass and Lowpass filters,
and Voice Symmetry.
• Configure named presets for each on-air
personality – up to 50, including factory
presets – using the included Windows®
software over Ethernet.
• Recall presets with convenient front panel
controls, optional hardware remote(s), or
third-party control protocol.

A&E Specifications
Performance Data
Mechanical Data
The device shall provide two inputs that are selectable as line or mic level
with phantom power and four outputs (two line level analog and two AES3
digital). All signal processing (including input gains) shall be controllable via
software. Audio inputs and outputs shall be accessed via rear panel XLR
Space Required:
1U (WDH: 48.02 cm x 23.11 cm x 4.37 cm / 18.91 in
x 9.1 in x 1.72 in), depth is specified from front panel
to back of connectors.
Allow at least 3 inches additional clearance for rear
panel connections. Additional depth may be required
depending upon your specific wiring and connections.
The Graphical User Interface (GUI) software shall be installer programmable
using the Windows® XP or Vista operating system. Computer connection
and control shall be via the device’s rear panel Ethernet connector. The GUI
shall provide display and control of all signal processing and configuration
functions including, but not limited to: Input and Output Gain, Highpass
Filtering, Lowpass Filtering, De-essing, Downward Expansion,
Compression, Parametric Equalization, Signal Routing, Voice
Symmetry and Polarity.
The front panel shall include input and output level indication as well as
indicators for POWER, NETWORK, and REMOTE. Additionally, a front panel
LCD shall display certain system parameters and may be used for preset
recall via the front panel UP, DOWN and MENU buttons.
External control shall include preset selection and/or comprehensive
parameter adjustment, depending upon the particular remote in use, and
shall be via industry-standard CAT5 cable with RJ45 connectors to the front
or rear panel REMOTE ports. All program memory shall be non-volatile and
provide program security should power fail. 3rd party control systems may
interface via Ethernet using a published Control Protocol.
Audio conversion shall be 24-bit, 48 kHz with configurable output sample
rate. The dynamic range of the processor shall not be lower than 113 dB
