Reference Line Preamp "Veracity No.48 MK4"

 
   

Powerful, deep bass, precise, transparent, spatial and very dynamic reproduction of music, 
  exact timing with live-character


* The use of a professional class A output stage determines a widely extended frequency
  response, a very good channel separation and an excellent harmonic spectrum


* Complex low-noise voltage stabilisation

* Layout optimized to shortest signal paths

* Relais with gold plated silver contacts

* ALPS high grade potentiometer

* Switchable output resistance

*
 Preamp and external 50VA power supply integrated in heavy, massive, solid high-end-
  casings with high glossy black acryl fronts and resonance absorbing polished chrome feet


* All input jacks and output jacks are gold plated

* Remote control for volume including a freely programmable,

  learnable infrared transmitter as an option avaliable (LAZYBONES)

* Every device comes along with "its own" original measuring record of the frequency response, 
  further measuring records are available on request


Special technical features:

ALPS high grade stereo-potentiometer for volume

With device back plate screwed massive gold plated
cinch jacks for durable mechanical stability

Big torroid transformer (integrated in the power supply)

Heavy, massive resonance absorbing chrome feet

Option: IR remote control

for Purist No.48 / Veracity No.48 / Continuance No.84

with complete internal electronic circuitry and with free programmable
and learnable IR-transmitter
