INTRODUCTION
Powered Speaker System
Thank you for choosing active
sound reinforcement speakers.
The PSR-15A is an active two-wayloud
speaker capable of extremely high sound
pressure levels, and designed to give you
the best performance of any loudspeaker
in its class and price range.
Our design goal was to build a sound reinforcement speaker with:
1.High precision, high output, and accu rate playback.
2.Very wide, smooth dispersion of mid and
high frequencies.
3.Ergonomically correct physical design
for easy transport and set up.
Through the combined resources of our
top-notch mechanical and analog engineers, we were able to achieve our design goals in every respect. The result is a sound
reinforcement system equally at home in
a concert setting, in the studio,in the cinema, or in a home theater.
PSR-15A,Our exclusive design useslownegative feedback, yet allows the amplifiers to maintain low distortion and stability
and to quickly recover when driven into clipping.
The amplifiers include the followingfeatures:
The low-frequency amplifier produces
up to 700 watts peak(350 continuous)
before clipping.
The high-frequency amplifier produces
up to 100 watts peak (50 continuous)
before clipping.
Each amplifier has its own compressor
circuit that acts when the input signal
is large enough to cause clipping, disto rtion and excessive voice coil heat. The
compressor will automatically decrease
the input signal to a safe level. The
compressor in the low-frepuency amp
works independently from that in the
high-frequency amp.
The low-frequency amp uses servo feed back loop which senses the current flo wing in the woofer coil. This controls the
low-frequency response and maintains
low distortion at high output levels.
The low-frequency amplifier also has a
seeping filter. This will automatically
move the low cut-off frequency up or
down depending on the amplifier output.
The Transducers
The PSR-15A active speakers feature
a15-inch high -power low-frequency woofer
and a 1.75-inch titanium diaphragm highoutput precision compression driver. This
high-frequency driver is mounted on an acoustically non-resonant exponential waveguide, providing a wide, controlled dispersion and precise reproduction of the critical upper mid-range and high frequencies.
The result is an unbelievably smooth offaxis response that allows everyone in the
audience to experience the same highresolution audio no matter where they are
seated.
Each driver has been specifically desiged by our engineers for optimum performance in the lightweight high-strength cabinet.
