E300
Multi-Pattern Condenser Microphone
Transparent, airy upper and mids, coupled with a rich, silky smooth low
end and an enormous upfront presence make the e300 our finest vocal
mic. The e300 offers unparalleled performance from critical studio tracking
scenarios to live sound reinforcement. The 1.1” 24K gold sputtered externally
biased triple pattern (cardioid, omni, figure-of-eight) dual diaphragm
condenser capsule is hand dampened for consistent frequency response.
A regulated bypass voltage generator for precise output sensitivity,
sophisticated laser trimmed op-amp circuitry for increased management of
fast transients and open capsule architecture design make the e300 a classic
vocal studio microphone. Features include an on/off switch with auto power
shut-off feature, hi-pass filter 6 dB pad/octave @ 135 Hz and a 20 dB pad.
Rechargeable 9V nickel hydride batteries provide huge current reserve
and allow for remote operation for up to 6 hours. Shock mount and
carrying case included. P48 (48V) phantom power is required.
