IGS Audio Pure Tube Channel_ENG
A new pre-amp has joined the group in the IGS Audio catalogue. It is framed in a one rack unit of a 19” chassis. It uses vacuum tubes as active elements and it is built with the usual high quality we know from IGS Audio. The unit is promising, let’s go check it’s performances.

The look (and the feel) is really vintage with big knobs and switches, quite enough space for fingers to operate and with a clear layout which makes everything clear without asking for the user manual. The front panel starts (from left) with an high impedence input followed by four big (backlit) white buttons for HiZ, Mic/Line, +48V and Phase adjust. The gain is tamed via a coarse switch with six positions to go from 10 to 60dB in steps of 10. Fine tuning is possible via the following stepped trim which is capable to go from -5dB to +5dB allowing to continuosly cover all the gain range from 5 to 65dB. Going further to the right there is a nice orizontal VU meter followed by the red jewel and the power switch.
