Fig. 1: HC 577 L micro-
phone
Refer to fig. 1.
The HC 577 L is a highly professional head-worn condenser mi-
crophone specifically designed for almost "invisible" use by
performers on stage and radio or TV moderators. In line with this
concept, the microphone is extremely light.
The dual-diaphragm microphone capsule (1) on the HC 577 L
features an additional gold-sputtered protective diaphragm that
prevents moisture and perspiration from penetrating into the
transducer. This reduces the risk of failure caused by humidity
to a practical minimum.
Both the microphone arm (2) and the microphone arm holder (3)
are removable. Therefore, you can mount the microphone arm
(2) either on the left or right temple piece (4). In addition, you
may snap the microphone arm into the microphone arm holder
at any desired point to adjust the distance between the micro-
phone and the user's mouth.
This modular design also allows you to mount a second micro-
phone, e.g., as a backup during an open-air opera perform-
ance, on the opposite temple piece. The microphone arm with
microphone and cable as well as the microphone arm holder
are available separately from AKG Service at [email protected].
As delivered, the microphone provides a virtually flat high-fre-
quency response. The supplied PB 77 presence boost cap lets
you boost the high-frequency range around 12 kHz by 3 dB.
