Polyribbon™
variable pattern ribbon microphone
INSTRUCTION MANUAL
DESCRIPTION
The Polyribbon is a variable pattern dual ribbon microphone with switch
selectable omnidirectional, hypercardioid, and figure 8 polar patterns. A 3 way
bass cut switch is provided to compensate for various proximity effects or to tailor
the bass response as desired. The microphone is passive and as such does not
require phantom power for operation. Output inpedance is 150 ohms. Connection
is by standard XLR male connector.
OPERATION
Preamp connection
A standard balanced XLR can be used for preamp connection. The preamp
should be a high quality low noise design with 2000 ohms differential input
impedance or higher and be capable of up to 60 dB gain. Phantom power is not
required.
Figure 8 setting
Most ribbon microphones exhibit a figure eight polar pattern.The front and back
have maximum sensitivity while the sides, top, and bottom reject sound.
On the figure 8 setting the polyribbon will exhibit this type of pattern as well.
The nulls are particularly deep and can used to reject unwanted signals. Typical

- Page 2 Many ribbons have a greatly reduced high frequency response due to tradeoffs that were made to increase sensitivity. As such they have a fundamentally different sound from more common condenser microphones. The Polyribbon has a full frequency response AND high sensitivity. It does not have the sound of typical condensers however.
- Page 3 axis response is much smoother as well. Finally distortion mechanisms inherent in gradient condenser microphones are absent. For these reasons ribbon mics tend to take EQ better when it’s desired for effect. Microphone care Ribbon microphones are sensitive instruments and must be treated with care: 1) Never blow into the microphone 2) Do not use in very high wind conditions 3) Do not use in high velocity fields such as kick drum ports or speaker...
