CLOSE UP: INGRAM ENGINEERING
CLOSE UP, MAGAZINE / FEBRUARY 21, 2022 / BY JONATHAN WIDRAN
My lifelong passion for writing and playing original music fed into my interest in creating original gear and once people started using these products regularly, it made sense to build Ingram Engineering around that.
Products for the modern studio
From the MPA685 Preamp:
"This is the kind of preamplifier I want to see more of in our world. It does what it's supposed to do and it doesn't add much else to the sound. ...built with care... to last several lifetimes." - Scott Dorsey, Recording Magazine
And the MPA575 Channel Strip:
“I loved using the MPA575. It's an incredibly adaptable piece of equipment that works well in practically any recording situation.” - Russ Long
To the EQ52 Equalizer:
“I had great success using the EQ52 as a stereo mastering touch up tool.” - Barry Rudolph, Recording Engineer/Producer
