T M E Q
TUBE MASTER EQUALIZER
The TMEQ is the ultimate 6 band stereo all tube Equalizer
based upon a tube circuit design from the late 60's.
The working principle is a frequency controlled amplifier.
The signal path does not get in contact with the frequency
dedicating components and will therefore perform with a
higher phase linearity. In fact, each of the 12 tube circuits
are frequency controlled amplifiers. The result gives an
outstanding and unique sound provided by the TMEQ.
Only switches are used on all controllers for precision
setting when used in the mastering process.
Technical Features:
The Tube Master Equalizer is totally hand build with great care
like all other Fairman products. It is a 19inch 6unit rack mounted unit.
The power supply is located outside the Equalizer as with the TMC and the TRC.
This design has proven to be the best solution to achieve absolutely no background noise.
The two main boards with 11 tubes on each are developed on a special quality
printed circuit board. A very thick oxygen free copper layer on stronger fiber
glass allows now the use of PCB's in high end tube constructions.
The 24 frequency and attenuator controllers are the Swiss made, high quality gold plated
ELMA 04 switches, fitted with precision components to assure perfect stereo tracking.
The function switches are driving small sealed relays with 4 sets of gold plated contacts.
They are placed locally in the circuits to optimize and shorten the audio signal path.
Each of the 12 amplifier circuits can be switched on or bypassed individually.
The main bypass is a true hardwire bypass which is connecting the input signal directly
to the output. A link function allows one hand bypass operation for both channels.
The main bypass switching is also remote controllable.
Input and output gain switches with settings from -6dB to +6dB in 0.75dB steps are provided
to meet the wide range of analog levels, when inserted in the digital mastering environment.
A green LED for each channel is indicating the correct internal "Zero VU" level.
