response and gain-before-feedback. The MB4
shall have a permanently attached 15-foot
(4.572 m) cable connected to an XLR-type con-
nector with built-in mic electronics. Powering
shall be by 12-48V phantom power.
At the output connector, nominal sensitivity shall
be 22 mV/Pa. Maximum SPL shall be 120 dB
SPL for 3% THD. Equivalent noise shall be 22
dBA nominal. Frequency response shall be 50
Hz to 15 kHz with a uniform off-axis response,
about 20 dB down at the rear nulls.
The AKG/Crown model MB4 is specified.
