Mono Tube MASTERING fullrange 7band EQ
The TUBE-TECH EQ 1AM is a full range one channel unit, featuring low and high cut, low and high shelving as well as three overlapping bands of equalization. The cut filters are designed around unity gain amplifiers and the shelving and the bell filters are designed around two tube operational amplifiers. The unit is all tube based except for the power supply. Input and output have fully floating transformers. All DC voltages are stabilized, except the anode voltage for the output stage.
The EQ 1AM is fitted with rotary switches instead of pots for even more precise recall of settings. This enables very precise recall for mastering use.
