at lengths of up to 300 m (nearly 1000') is

Power-on Behavior

When powered on, the SuperCMIT may

require up to 15 seconds to become ready for

use. Varying amounts of noise may be pro-

duced during this time; such behavior is

entirely normal.

Operation

The SuperCMIT has two output channels:

Channel 1: ”SuperCMIT” (enhanced directivity;

processed signal from both transducers)

Channel 2: ”CMIT” (normal directivity;

unprocessed signal from the front-facing

transducer)

Both channels are affected simultaneously by

the filter switches.

Green LED = ”Filter off”, red LED = ”Filter on”

High-frequency boost: +5 dB at 10 kHz – to

compensate for losses due to windscreens

Steep low-cut: 18 dB/Oct. below 80 Hz – to

suppress wind and boom noise

The Preset button selects the directivity of the

”SuperCMIT” (Channel 1):

– Preset 1 (green LED): Increased directivity;

11 dB suppression of diffuse sound, which

is 5 dB greater than CMIT.

– Preset 2 (red LED): 15 dB (extremely high)

suppression of diffuse sound. This setting is

reserved for special applications; some less-

ening of sound quality may occur.

Suggested applications

The SuperCMIT 2 U is suggested for use wher-

ever there is interference from diffuse sound

such as street noise, rustling leaves, wind noise,

sound from passers-by or onlookers, or room

reverberation in a recording. The interfering

sound is reduced significantly in level without

affecting the sound color of directly arriving

sound, even down to the lowest frequencies.

This makes the SuperCMIT ideal e.g. for diffi-

cult film sound assignments and sports broad-

casts.

The SuperCMIT also extends ”reach” for

indoor recordings.

Connecting the SuperCMIT

Input / Powering

The SuperCMIT's output is digital, complying

with AES42, Mode 1. It requires digital phan-

tom powering (10 V), which is supplied via

the signal cable as with analog microphones.

Because it operates in Mode 1, the micro-

phone provides its own clock (48 kHz). Thus

the input of the interface device or recorder

must provide sampling rate conversion if the

microphone is to be operated synchronously

with other equipment.

AES42 Mode 1 inputs are available on cer-

tain equipment, e.g. the 8-channel DMC-842

interface from RME and the Sound Devices

788T 8-channel portable recorder. For further

information please see www.schoeps.de/

digital and www.hauptmikrofon.de/aes42.

The SuperCMIT can also be used with AES3

inputs if digital phantom powering is supplied

(e.g. by the PSD 2 U – see ”Accessories”)

between the input and the microphone.

The Cable

Ordinary analog XLR cable can be used, but

its characteristic impedance is undefined; thus

we cannot guarantee reliable operation of the

microphone particularly with long cables. If an

AES3-standard XLR-3 cable with a characteristic

impedance of 110 Ω is used, then operation
