The 8304's all-discrete, bipolar transistor circuit topologies are completely transformerless with no FETs, ICs, or electrolytic capacitors in the signal path. Even the outputs are direct-coupled; proven active servos remove DC without adding any artificial color.

From 15dB up to a whopping 70dB of amplification, the 8304's input gain is selectable in precise 5dB steps. It accommodates all sources from low output ribbon mics through semi-pro keyboards to inserts in super hot mastering chains with one knob. A +24dBv CLIP indicator warns of any impending overloads and switchable phantom powering is built in.

Great Unit

This unit is really great. Transparent, clean, tons of headroom. I only have one problem with this pre and it bugs me alot. Why are the Phantom Power switches on the back? It really can get annoying sometimes. Otherwise, great.
