AKG Acoustics C900 - Manual

C 900
Emotion Series II Condenser Cardioid
Description
The AKG Model C 900 is a rugged condenser cardioid
microphone intended for on-stage instrumental and vocal
pickup. Its extremely uniform polar pattern assures immunity
to feedback and makes the C 900 ideal for use with in-ear
monitoring systems. Due to new patented backplate
construction, the C 900 maintains very uniform frequency
response, and the PB 1000 presence boost adapter adds 3
to 4 dB of response above 5 kHz for increased presence. The
microphone capsule has been carefully shock mounted for
low handling noise, and the spring steel grille is durable and
easily removable. The light-weight body is die cast zinc alloy
and has a soft touch finish for comfort and secure handling
to minimize reflection and glare. A gold trim ring enhances
the appearance. The microphone includes a stand adapter
and carrying bag.
