Compact Concert Loudspeaker System

Compact Concert Loudspeaker System
FH-4
Compact Concert
Loudspeaker System
Description:
The FH-4 is a high-power, three-way,
tri-amped loudspeaker representing
the pinnacle of achievement in
concert class sound reinforcement.
It's characterized by a smooth
natural sound, even at very high
volume levels.
Driver Complement:
Low Frequency: One Apogee 15"(381mm) permanent magnet conetype driver is treated with a waterproofing compound, providing
resistance to moisture, and enabling long-term stability of cone
resonance and cone mass parameters
Mid Frequency: One Apogee 10"(254mm) fluid-cooled, low
distortion cone is coupled to a highly damped waveguide
constructed of formed wood
Engineering Data:

FH-4 Polar Measurements
All polar measurements obtained in a free-field environment at 10 degree
increments. Data acquired utilizing: TEF System 12+, B&K 4007 Mic, HP 35660A
Dual-Channel FFT Analyzer.
The PFH-4 processor is available in three versions to meet
the requirements of permanent system installers and portable system
operators. Each includes servo-loop protection circuits, time and
frequency domain correction, and a precision front end utilizing
factory-matched components for high Common Mode Rejection. All
models feature front panel function switches (which retain their
settings through power-up/power-down cycles), turn-on/turn-off
muting and Apogee's unique PAR™ adjustable protection circuitry. PAR
(Positive Amplifier Return) senses the output of the amplifier and
engages low distortion limiters to aid in protecting the drivers under
abusive conditions. By selecting a "User Preset" mode, the protection
circuits can be adjusted to match a wide range of power amps.
