Architect and Engineer Speci fi ca tions
Compression driver unit shall be Atlas Sound Model _____PD-30
& PD30T or approved equal. Full range integrated speech and music
program handling capacity shall be 30 Watts, above the low frequency
cut-off of the projector horn.
Rated frequency response shall be __________ Hz (±5dB) measured on
a plane wave tube at 1W/1M. Low frequency limit at full power shall be
_____ Hz. Sound pressure level output capability shall be 113.6dB (avg.)
300Hz - 3.9kHz (±5dB) measured on a plane wave tube at 1W/1M.
Driver with enclosed terminal shall be capable of standard indoor/
outdoor use and be fully environment-resistant. The units shall terminate
in the industry standard 1
3
⁄8"–18 thread pattern and a .707" throat.
Diaphragm shall be field-replaceable and shall be high-temperature
molded phenolic with a roll-type, flex-point suspension.
Model PD-30 shall have a nominal impedance of 8Ω. Unit PD-30T shall
be equipped with a 70.7V transformer having power taps of 1.8, 3.7, 7.5,
15 and 30 Watts.
Impedance and power taps shall be clearly identified and referenced on
the unit.
NOTE: Plane wave tube measurements provide resistive loads to test drivers.
Actual frequency response of a driver / horn combination will vary depending on
the horn used with the driver. Consult individual horn specification sheet for typical
horn frequency response.
