Precision Series Modular Amplifiers

QRx™ loudspeakers deliver great sound and versatility because the
QRx design team took the time to get everything right. QRx loudspeakers are packed
with Electro-Voice® technical innovations and 70 years of sound reinforcement
know-how. That gives the QRx family unexpected features to help you solve difficult
room acoustics and installation problems:
The newest members of the Precision Series™ amplifier family were designed specifically to power QRx loudspeakers.
The primary difference between the P1202/P1201 and other Precision Series amps are the module slots that accommodate
processor modules for each QRx loudspeaker. Without modules plugged in, the P1202/P1201 are linear amps with +6 dBu
fixed input sensitivity. Otherwise, the P1202/P1201 perform just like their
Precision Series siblings, giving you:
• High dynamic headroom with life-like transients.
• Dynamic limiters prevent clipping. Distortion can’t exceed 1%,
eliminating the #1 cause of loudspeaker failure.
• Complete protection package against signal, power, and thermal faults.
The P1202 dual channel amplifier delivers 600 watts per channel
into 4 ohms. Equipped with two module slots, the P1202 drives either two
completely independent signals, or a signal can be routed to both
amplifier channels via a single module.
The P1201 single channel amplifier offers 1,200 watts into 4 ohms,
ideal for driving subwoofers. When A and B inputs are connected, they’re
summed to an internal mono signal.
Rotatable asymmetric HF horn lets you project the
sound exactly where you want it to go. Instead of a typical
horn pattern, the QRx HF horn has a versatile 75° x 50°
(up 15°/down 35°) pattern. You can, for example, mount a
QRx112 cabinet horizontally against a ceiling, then rotate the
horn so more sound covers the audience and isn’t sprayed
on the ceiling.
Top-line Electro-Voice components make QRx loudspeakers pleasing to the ears of
everyone from DJs to string quartets. The new DH7 compression driver features a large
format, 3-inch voice coil and titanium diaphragm for great
sound quality even when the system is pushed.
QRx subs deliver hard-hitting, reliable bass
response with the same EVX-180B
18-inch woofers with 4-inch voice coil
used in EV® X-Array™ and X-Line™
concert systems.
External passive/biamp switch
eliminates the hassle of opening the
cabinet and rewiring the speaker for
biamp operation.
Exclusive Electro-Voice ® RMD® Ring Mode Decoupling
technology—originally developed for our touring concert
loudspeaker systems—minimizes acoustic and
mechanical resonances in the cabinets that can
color the sound. The result is incredibly clear
vocals; and full, dynamic sound
that doesn’t change, even at
the highest sound levels.

Loudspeakers
and Precision Series Modular Amplifiers
™
Precision Series Modular Amplifiers
™
QRx™ loudspeakers deliver great sound and versatility because the
QRx design team took the time to get everything right. QRx loudspeakers are packed
with Electro-Voice® technical innovations and 70 years of sound reinforcement
know-how. That gives the QRx family unexpected features to help you solve difficult
room acoustics and installation problems:
The newest members of the Precision Series™ amplifier family were designed specifically to power QRx loudspeakers.
The primary difference between the P1202/P1201 and other Precision Series amps are the module slots that accommodate
processor modules for each QRx loudspeaker. Without modules plugged in, the P1202/P1201 are linear amps with +6 dBu
fixed input sensitivity. Otherwise, the P1202/P1201 perform just like their
Precision Series siblings, giving you:
• High dynamic headroom with life-like transients.
• Dynamic limiters prevent clipping. Distortion can’t exceed 1%,
eliminating the #1 cause of loudspeaker failure.
• Complete protection package against signal, power, and thermal faults.
The P1202 dual channel amplifier delivers 600 watts per channel
into 4 ohms. Equipped with two module slots, the P1202 drives either two
completely independent signals, or a signal can be routed to both
amplifier channels via a single module.
The P1201 single channel amplifier offers 1,200 watts into 4 ohms,
ideal for driving subwoofers. When A and B inputs are connected, they’re
summed to an internal mono signal.
Rotatable asymmetric HF horn lets you project the
sound exactly where you want it to go. Instead of a typical
horn pattern, the QRx HF horn has a versatile 75° x 50°
(up 15°/down 35°) pattern. You can, for example, mount a
QRx112 cabinet horizontally against a ceiling, then rotate the
horn so more sound covers the audience and isn’t sprayed
on the ceiling.
Top-line Electro-Voice components make QRx loudspeakers pleasing to the ears of
everyone from DJs to string quartets. The new DH7 compression driver features a large
format, 3-inch voice coil and titanium diaphragm for great
sound quality even when the system is pushed.
QRx subs deliver hard-hitting, reliable bass
response with the same EVX-180B
18-inch woofers with 4-inch voice coil
used in EV® X-Array™ and X-Line™
concert systems.
External passive/biamp switch
eliminates the hassle of opening the
cabinet and rewiring the speaker for
biamp operation.
Exclusive Electro-Voice ® RMD® Ring Mode Decoupling
technology—originally developed for our touring concert
loudspeaker systems—minimizes acoustic and
mechanical resonances in the cabinets that can
color the sound. The result is incredibly clear
vocals; and full, dynamic sound
that doesn’t change, even at
the highest sound levels.

and Precision Series™ modular amplifiers.
Electro-Voice Precision Series modular amplifiers were designed to power the
QRx loudspeaker family, and simplify the task of optimizing the amps to match
the speakers. For years, the legendary German engineered-and-built Precision
Series amplifiers have been a dependable favorite for concert sound systems.
These two modular versions offer the same features—incredible dynamic
headroom, low distortion, and extreme protection circuitry—plus plug-in
filtering/processing modules that match specific QRx loudspeakers.
™
The modules reduce setup time and eliminate the need for outboard processing.
And they contain QRx-specific circuitry such as the LPN processor that provides
complete bass reproduction in all QRx full-range and subwoofer models.
