Introduction
When recording acoustic instruments or vocals, using a microphone is inevitable. The actual output level of a microphone is very low and therefore has to be boosted to studio or line level (0 dB) with a pream- plifier. Sometimes signals have to be boosted by a factor of 2000 or more. As a consequence, the resulting sound quality provided by the preamp is of paramount importance, so a good microphone preamp that does not overdrive is the definitive requirement in order to record acoustic instruments or vocals with sufficient dynamics and untainted sound.
The section “Technology” from page 14 explains how the Preference
Mic Pre meets these requirements.
Main Features
The Preference Mic Pre offers preamplification values of up to +72 dB with lowest noise operation and a high common mode rejection.
A VU meter with two modes for average levels (VU) and peak levels (PPM) displays the output levels.
A very stable phantom power supply (48 V) is provided to power con- denser microphones.
The polarity of the microphone can be switched with the phase reverse switch.
A
Two LEDs are placed into the VU window to concentrate all displays in one area.
The signal LED (SIG.) indicates that an input signal is present, the overdrive LED (OVL) warns against potential overdrives.
