TRANSISTORIZED BASE STATION MICROPHONE
GENERAL
The Shure Model 526T Series II SUPER PUNCH
base
station microphone is designed for clearer transmission and
improved reliability. This transistorized microphone can be
used to replace ceramic or dynamic, high- or low-impedance
microphones supplied as original equipment.
Model 526T Series II provides crisp, undistorted voice re-
sponse with adjustable volume control for optimum intelligi-
bility of transmission.
The microphone is designed for maximum versatility in
base station operation. It has a momentary or locking press-
to-talk transmit/receive switch for greatest ease of use, and
a modulation level volume control for highest undistorted
output with high- or low-impedance inputs. The supplied six-
wire cable and triple-pole double-throw switch are arranged
for universal microphone-transceiver connection.
The microphone is not affected by heat or humidity, and it
is oustanding in its ability to resist mechanical shocks and
vibration. Its exclusive ARMO-DUR
case is immune to oil,
grease, fumes, salt spray, sun, rust, and corrosion. The “Mil-
lion Cycle” leaf-type press-to-talk switch is designed to with-
stand rigorous operating conditions and constant use.
