Quad Eight Coranado - featuring
the discrete AM-10 amplifier module

RCA Mixer - on the left as it arrived
in the workshop. These are a not uncommon four into one mixer
typically used by Broadcasters for "field" broadcasts.
Dead simple three transistor amplifiers and bucket loads of
gain.
Below is what I did to it - Now a four channel preamp with
individual outputs, variable 30dB input pad, phantom and phase
rev.
Here's what the owner had to say about the completed unit
-
"Had a good run with the unit now.. It is VERY worthwhile
getting this work done to it...
It looks freaking amazing first off...
Secondly, the sound is very smooth. Ive tried it on some drums,
(overhead, room, anything with cymbals in them really)...
It mellows out the ear hurty stuff, but still sounds clear
and open... It handles processing really well too. If i need
more tops, it brings out a smooth non pokey top end....
On vocals, Very good.. Im loving them here heaps... Used
these pres with both dynamic ,condenser, and tube mics on
vocals. All are a win... This chap had a funny 'shh' sound
whenever an 's' sound appears.. It was alot less obvious with
this pre compared to Vintechs and API..." - Dave
