Shure DFR11EQ5 Half Rack Digital Equalizer/feedback reducer/delay/limiter - all in one

DFR11EQ Digital Equalizer Shure's DFR11EQ is a computer-controlled digital equalizer with a multitude of audio processing capabilities offered in a compact, half-rack unit. The innovative DFR software interface runs on Windows® and makes even the most complex processing functions easy to use.


A full–featured signal processor designed for sound reinforcement
applications, including theaters, conference
rooms, meeting halls and houses of worship. The DFR11EQ
offers a straightforward computer control interface that
makes sense without a software manual or training course.
The system also features tamper–proof front panel lockouts
and the exclusive ShureLink network, which controls up to 16
units from one computer connection.
The DFR11EQ is a true problem-solver with features including
10 automatic, adaptive, feedback filters, equalizer
limiter and delay for challenging acoustical situations.


* Crystal* 20-bit A/D and D/A converters (Analog-to-Digital,
Digital-to-Analog) allows 104 dB of dynamic range.
* 48 kHz sampling rate provides flat response to 20 kHz.
* Onboard Scenes can be selected via front panel buttons.
* 1/2 rack space chassis allows rack mounting of one or two
units in a single rack space with no sagging or bending.
* Shure Link Interface allows multiple Shure Link devices
to be controlled with a single computer.
* There are no internal batteries. Settings and DSP program
are stored in internal EEPROM.
* Electronically balanced input features combination 1/4-in.
and XLR connector and can be used with balanced or
unbalanced outputs
* Independently driven, cross-coupled, balanced 1/4-in.
and XLR outputs can be used with balanced or unbalanced
inputs, without signal loss.
* Input and output levels are +4 dBu/–10 dBV DIP-switchselectable.
* 88 MHz Motorola* DSP56009 processor engine features
full 24-bit internal processing.
* RS-232 interface allows external computer control and
firmware updates.
* Internal linear power supply is switchable between 120
and 230 Vac, eliminating the need for a cumbersome external
power supply.
* Solid state bypass eliminates unreliable mechanical relays


* Adaptive Notch Filter algorithm (patent pending) automatically
detects feedback and deploys up to 10 narrow
band notch filters.
* A tamper-proof equalizer can be switched between
30-band graphic or 10-band parametric equalizer.
* The graphic equalizer is a constant-Q, 30-band, 1/3-octave
graphic equalizer. It can boost up to 6 dB or cut 12 dB for
each band.
* The parametric equalizer offers 10 filters with adjustable frequency, up to 6 dB of boost or 18 dB of cut, and up to
a two octave bandwidth.
* Up to 1.3 seconds of Digital Delay.
* Front and back panels both feature lockout control.
* The Response Curve Viewer displays frequency response
of the feedback reducer, equalizer, or both.
* 10 scenes can be stored on board. Multiple scenes can
be stored to floppy or hard disk.
* The Limiter provides added protection to external speakers and amplifiers.
