Proscenium:

Features at a glance

Traditional warm ribbon response

Figure eight polar pattern

High output microphone designed for classical music applications and as stereo pairs in concert halls

All new design with innovative motor unit and a rugged stainless steel housing

Transformer and ribbon motor rigidly joined for lowest noise, highest output and smoothest bass

Professional level electrostatic and magnetic shielding

Symmetric frequency response minimizes off axis coloration

Specifications microphone compiled by an independent laboratory

Hand built in the U.S.A. by people who understand the art of transducer engineering, tuning, and performance

Never blow directly into any microphone. Inform performers of this precaution.

Amplification

The Proscenium is a low noise microphone. The combination of its efficient transducer, robust shielding, and full size transformer

give the microphone a low noise floor and output level equal to moving coil (dynamic) microphones. Certain ribbon designs have

weaker magnets and less shielding, and require up to 30 dB of additional gain for optimum performance. This is not the case with the

Proscenium. Most professional level preamplifiers with normal gain and high input impedance are well suited for the Proscenium.

The Proscenium, like all ribbon microphones, performs optimally with the least amount of loading on the ribbon element as practical.

The higher the impedance input on the microphone, the better the low end and mid range frequencies are represented in the output

signal. We recommend using preamps with impedance settings of 1000 Ohms or more. Contact us if you would like specific preamp

recommendations.

The Proscenium is quite natural sounding and does not require coloration at the preamp stage for optimal performance. Preamps that

provide simple, transparent gain usually provide the best results. However, you may prefer a more colored sound, and we encourage

you to experiment to find the right combination that suits your taste.

The Proscenium is an acoustically driven ribbon microphone, which means that no power supply is required for its operation. +48

Volt phantom power will not burst the ribbon element, but over time, exposure to phantom power and switching transients will affect

the overall output of the system. Therefore, disable this function when using the Proscenium.

The Proximity Effect

The proximity effect is an acoustic phenomenon that can be very useful in creative recording. Bass response increases as a function of

microphone distance from the sound source. In a nutshell, the closer the microphone is to the sound source, the higher the bass response

will be.

An understanding of the proximity effect enables the user to fine tune bass response. Appropriate placement of the microphone differs

from application to application, and as with any microphone, the best way to hit the sweet spot for your application is to experiment with

different distances and angles from the sound source while listening.

Weak, thin vocals can be significantly enhanced by reducing distance, and other instruments can be fattened, if desired. For vocals

closer than about 8", a pop screen is recommended.
