ARCHITECT AND ENGINEER SPECIFICATIONS

PD-60A Impedance

PD-60A Plane Wave Tube Response

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.

Compression driver unit shall be Atlas Sound Model _____

PD-60A, PD-60AT or approved equal. Unit shall have a full

range power capacity of 60 watts above the low frequency cut-

off of the associated projector horn.

Rated frequency response shall be 100-3,700 (+5dB) measured

on a plane wave tube at 1 mW. Unit shall have a ceramic mag-

net and each driver shall have a sound pressure output capabili-

ty level of 112.7 (avg) 100-3,700Hz (+5dB). Low frequency limit

at full power shall be 300Hz. Compression driver shall have a 16

ohm voice coil of 2" diameter constructed of cloth-base molded

phenolic.

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

⁄8"–18 thread pattern

and a .707" inch throat.

Diaphragm shall be field-replaceable and shall be high-temper-

ature molded phenolic with a roll-type, flex-point suspension.

Models PD-60A shall have a nominal impedance of 16 ohms.

Unit PD-60AT shall be equipped with a 70.7 volt transformer

having power taps of 2.5, 5, 10, 20, 40 and 60 Watts.

Impedance and power taps shall be clearly identified and refer-

enced on screw-terminal board.
