TUBE-TECH ME 1B

mid equalizer

DESCRIPTION

The TUBE-TECH program equalizer ME 1A contains a passive filter and a tube (valve) based
amplifier to restore the loss from the filter.
The filter has a low frequency peak section with 5 selective frequencies, a mid frequency dip
section with 11 selective frequencies, and a high frequency peak section with 5 selective
frequencies.

The filter is placed directly after the input transformer, therefore eliminating noise from the
amplifier when boosting either low- or high frequencies.

The amplifier consists of two tubes (valves) in push-pull configuration (one ECC 83 as the
pre-amp, and one ECC 82 as the output stage), and an output transformer.

Both input and output are balanced (600

) and fully floating.

The in/out key switches the equalization in and out without clicks and changes in level, while the
amplifier remain in the signal path.
