DP11EQ DIGITAL SIGNAL PROCESSOR
The Shure Model DP11EQ is a single-channel, digital
signal processor that combines a comprehensive dynamics
processor, two parametric equalizers, and a delay in a single,
half-rack enclosure. The DP11EQ can function as a gate, expander, Automatic Gain Control (AGC) leveler, compressor,
limiter, and no overshoot peak limiter. All of these features
are accessed via the supplied Windows* software. You can
connect a computer to set up the unit in a sound system, then
remove the computer so no one can tamper with the settings
when the unit is left unattended. The DP11EQ is designed
for installed sound reinforcement applications: theater, conference rooms, meeting halls, houses of worship, etc.
DATA
HARDWARE FEATURES
S Crystal* 20-bit A/D and D/A converters (Analog-to-
Digital, Digital-to-Analog) for 104 dB dynamic range.
S 48 kHz sampling rate for flat response to 20 kHz.
S Half-rack space chassis allows rack mounting of one
or two units in a single rack space with no sagging
or bending.
S Shure Link Interface allows multiple units to be pro-
grammed with a single computer.
S Independently driven, cross-coupled, balanced
1
/4-inch and XLR outputs. Can be used with bal-
anced or unbalanced inputs.
S Electronically balanced input with combination
1
/4-inch and XLR connector. Can be used with bal-
anced or unbalanced outputs.
S No internal batteries. Settings and DSP program
stored in internal EEPROM.
SOFTWARE FEATURES
S Four (4) processing blocks: pre-dynamics equalizer
(EQ1), dynamics (DYN), post-dynamics (EQ2), and
Delay.
S The dynamics processor functions as a Gate, Ex-
pander, leveler, Compressor, Limiter, and No Overshoot Peak Limiter.
S The parametric equalizer offers up to 10 filters with
adjustable frequency, up to 6 dB of boost or –18 dB
of cut per filter,

/40 to 2 octave bandwidth.
S +4 dBu/–10 dBV DIP-switch-selectable input and
output levels.
S 80 MHz Motorola* DSP56009 processor engine with
full 24-bit internal processing.
S RS-232 interface for external computer control and
firmware updates.
S Internal linear power supply eliminates the need for
a cumbersome external power supply.
S Solid state bypass eliminates unreliable mechanical
relays and switches.
S A SIGNAL presence and a CLIP indicator
S DYNAMIC GAIN meter.
S Shure Link connectors for networking to other Shure
Link devices, such as the models DFR11EQ and
UA888.
S Response Viewing. The dynamics and equalizer
windows each have a viewer which shows the effect
of the process on the signal.
S Up to 1.3 seconds of Digital Delay with temperature
compensation option. Displayed in time and distance.
S Digitally-controlled signal polarity inverting for equip-
ment that inverts balanced signals.
S Front panel lockout control to prevent tampering.
S Storage of multiple scenes to floppy or hard disk.
