TRIODE TR-EQ1

Commentary

Phono equalizer amplifier using equalizer module of DACT Co.

The amplifier section is equipped with CT-100, an amplifier module for ultra-precision RIAA equalization made by DACT of Denmark.
This module has a highly reliable DIP switch and three selectable constants of voltage gain, input resistance and input capacitance. It is compatible with most commercially available MC/MM cartridges. The circuit uses the best semiconductor available at the time and a low-noise, non-inductive SMD metal film resistor (made in Germany).

The power supply has a dual monaural configuration, and the ± low-voltage circuit provided for each channel realizes a complete dual monaural configuration.

The output jacks are both balanced and unbalanced.

The time constants of 3.18 μ sec (50 Hz) and 7950 μ sec (20 Hz) can be individually selected and added by changing the characteristics of both high and low ranges of the normal RIAA characteristics with a DIP switch.

Designed to remove part of the top plate for DIP switch adjustment.
