Apex591

Owner’s Manual

The Apex591 is a high quality, high sensitivity, wide range unidirectional
condenser microphone designed for studio or stage. It is the ideal choice
for any recording or live sound reinforcement application where a tight
cardioid pickup pattern is needed to isolate and capture a high quality
sound source, while reducing unwanted background noise and providing
low feedback potential.

Built for virtually any audio application (including field recording) the
rugged Apex591 will operate with either phantom power delivered
from a console or preamp, or from an internal 9-volt battery when
phantom power is not readily available.

A recessed three position pad switch (0, -10dB, -20dB) is located in the 
battery compartment (above the battery box, under the battery cover) 
ensuring the pad switch is not inadvertently reset when the microphone is
slipped in and out of the microphone clip.

Use the pad to reduce the microphone’s input level when close miking high
sound pressure sources like brass and woodwind instruments or when using the
Apex591 on drums or percussion instruments as required.

The easily accessible recessed low-frequency roll-off switch (which 
doubles as the microphone’s power switch) allows the user to reduce low 
frequency ‘clutter’ in the audio signal at the source, making for cleaner recorded tracks with increased presence
and definition. Put this switch in the off position to preserve battery life when the Apex591 is not in use.

Applications:

Ideal for use on drum kits, percussion instruments and hi hats, or for overhead on drum kits. The Apex591 also
excels when used on acoustic guitars, stringed instruments, acoustic pianos, brass or woodwind instruments.
