After a few years of use here and abroad, we're selling a limited bunch to the outside world. The EApreq was born out of a need for another general use, transformer input, high performance preamp for our studio. It is a two channel transformer-based microphone preamp/eq designed to allow the character of the input transformer to color the sound with very little amplifier noise or distortion. The shelf eqs are boost only, to broadly add bass and/or treble. Dead simple. A design premium was placed on long term reliability, and flexible application. All of these preamps are hand built here at the studio. The Basics Low distortion Lundahl input Transformer. Provides slight coloring as input level gets higher. -20dB input pad switch - sealed gold contact relay Polarity reverse switch - sealed gold contact relay across the output for quietest operation 48v phantom power switch - standard application 16-position, gold contact, rotary gain switch ranging from 20 to 65dB of gain, 3dB per step. Low and High frequency shelf boost eq. controlled with a solid multi-section gold contact switch, 5 gain positions. A sealed relay bypasses the eq circuit when not in use. DC servo for both preamp gain and shelf eq make-up gain amplifiers. This provides long term predictable operation and sonics, avoiding the gradual decline that comes with electrolytic capacitor-coupled circuitry Ground-sensing solid state balanced output amplifier capable of driving 600Ω loads with ease, balanced or unbalanced. Clear green LEDs indicating which shelf band is engaged. Bright, amber colored "peak" LEDs signal just before clipping. Low magnetic field radiating Mu-metal shielded toroidal power transformer Red backlit logo badge to let you know the box is on. Please call or email us if you have any questions.
