The 6176 Channel Strip
Thank you for purchasing the 6176 Channel Strip. This unit brings together 1 channel of
our 2-610 Mic Pre with an 1176 Limiter. The 610B was inspired by the microphone
preamp section of the 610 console designed by my father, M.T. “Bill” Putnam, in the
1950s. The 610 was a rotary-control console and was the first console of the modular
design. Although technologically simple compared to modern consoles, the 610
possessed a warmth and character that kept it in demand for decades. As a prominent part
of my father’s United/Western studios, the 610 was used on many classic recordings by
Frank Sinatra and Sarah Vaughan. The Beach Boys Pet Sounds, the Doors LA Woman,
and Van Halen’s debut album were all recorded on the 610. The legendary Wally Heider
used the 610 in his remote truck for many of his best-known live recordings. At Ocean
Way Studios (formerly United), the 610 is lovingly preserved and still used in Studio B.
You may be familiar with the fact that there were many versions of the 1176 produced
throughout the years. We patterned our reproduction on the D/E versions. These versions
were characterized by the transformer input stage, LN circuitry, and the class A (1108
style) output stage. Later versions replaced the class-A output stage with a push-pull
class-AB output stage, and eventually replaced the transformer input with a differential
op-amp circuit. That highly recognizable blackface 1176 sound was best captured by the
version that we are reproducing.
In addition to the 1176LN and 2-610, Universal Audio has released reproductions of the
classic Teletronix LA-2A Leveling Amplifier and the 2108 microphone preamplifier
which is based on the 1108 line amps that were used in my father’s studios. Universal
Audio also creates software emulation’s of our vintage hardware that run on our UAD-1
DSP card as well as Digidesign’s Pro Tools platform. All of these products are designed
to meet the demands of the modern recording studio, yet retain the character of vintage
equipment.
These products have been quite an enjoyable adventure to develop and we’re sure the
next phase will be even more fun! We thank you for your support and we thank my
father, Bill Putnam.
Thank you,
Bill Putnam
