Clef Audio Conductor-LP solid-state phono preamplifier.

Overview

Conductor-LP is a solid-state phono preamplifier.  It plays both MM (Moving Magnet) and MC (moving Coil) - Standard Output and Low Output without the need of Step-Up Transformer
Conductor-LP is designed to accept 2 inputs simultaneously (MM + MC) and desired input can be chosen by selector switch on front panel.  The output is provided to both Unbalanced (RCA) and Balanced (XLR).
 

Technology

Low Noise High Gain Design Circuit:   The Conductor-LP has a very accurate RIAA equalization curve. This curve is accurate to better than 1/10 dB over 10 octaves.
The accuracy of this curve does not vary with an adjustment change of gain or cartridge loading.
Conductor-LP features gain adjustable from between 40dB and 76dB; a range sufficient to allow successful operation of not only high output moving magnet cartridges, but also the lowest output moving coil cartridges without the use of an auxiliary step-up transformer.

Dual mono design topology:   This gives the better isolation between channels.  Soundstage imaging is improved, offering true soundstage width and depth.  Instrument placement and layering are more accurate.
