![]() This can be useful when using the WA76 in conjunction with a high-gain preamp that doesn’t have a user-adjustable output control, such as Warm Audio’s excellent WA12. Incidentally, on the rear panel is an Input Pad button, which reduces the incoming signal by 23dB. The input pot, which is a true 600ohm t-pad, controls the signal level entering the unit and it also controls the compression threshold – as the dial is turned up, more compression or limiting takes place. Warm Audio has modelled the WA76 after revision D, arguably the best-sounding 1176 of all. This revision employed new low-noise circuitry that reduced the noise floor by 6dB, and thereafter the units were renamed 1176LN (low-noise). Over the years the 1176 went through several revisions, the most important of which was revision C, dating from 1970. When the original 1176 appeared in 1967 it quickly found favour in studios across the USA, usurping Universal Audio’s LA-2A levelling amplifier, often thought of as the 1176’s thermionic forefather. ![]() Putnam was already a pro-audio innovator having built the first mixing consoles that could be used in conjunction with multi-track tape recorders. Bill Putnam, founder of UREI, began work on the FET-based 1176 in 1966 when solid-state technology was in its infancy. Once Upon a Time… Let’s take a little look at the history first. It’s a solid, elegant design that’s much-loved for its functionality as well as its familiarity, both in terms of usability and sound quality. Vintage-gear junkies will recognise the familiar features of the WA76: two large rotary pots for input and output, two smaller pots for attack and release, and a large VU meter flanked by two rows of push-buttons. Like the original 1176 units upon which it’s based, the WA76 is a solid-state design utilising a Class A line-level output amplifier. ![]() ![]() The WA76 is a single-channel, 19in rackmount 2U compressor/limiter. ![]()
