The Coles 4038 Studio Ribbon Microphone is a BritishBroadcasting (BBC) design for broadcasting and recordingapplications.  It is used where a clear smooth wideuency response, absence of transient distortion and relativelyhigh sensitivity is essential.

The 4038 is a proven performer, and is in use around the worldby broadcasting networks such as the BBC as well as top engineersand studios on hit recordings.

Frequency response of the 4038 is exceptionally flat from 30 to20,000 Hz and throughout this range the shape of the bi-directional(figure of eight) polar response is maintained substantiallyconstant both in the horizontal and vertical planes, giving anatural sonic with smooth frequency response.

Features:
Pressure gradient transducer ribbon microphone  
Substantially flat frequency response from 30 to 15,000 c/s
Extremely low (non-linear) distortion
Exceptionally low hum pick-up
Bi-directional (figure of eight) polar curve shape accuratelymaintained in both horizontal and vertical planes
Excellent transient response
Natural clear balanced response to sound signal
Body shape to enhance acoustic performance
Clear natural high fidelity sound reproduction
Smooth sonic textured response
All microphones factory tested in free field conditions

Specifications:
Ribbon: Low mass damped ribbon to control transient response
Polar Response: Bi-directional
Magnetic Fields: By use of hum neutralizing wiring and magneticshielding of the toroidal ribbon to line transformer 30 to 40 dBreduction is achieved in response to stray disturbing magneticfields
Frequency Response: 30 Hz to 15,000 Hz
Impedance: 300 ohm
Sensitivity: -65 dB W.R.T. IV/Pa
Distortion: Less than 1% at 125 dB SPL
Connection: By means of 4069 3 pin jack plug. Pin 1 positive - Pin2 negative - Pin 3 screen
Body Housing: Made of heavy gauge perforated brass backed by finelywoven Monel mesh. Rotating hinge connection allows microphone totilt through 90° and turned in any direction when either suspendedor free standing
