A Trident Console for Your 500 Series Rack

The Trident Audio Developments 80B packs the sound of the company's storied '80s-era consoles into a full-featured 500 Series module. This pristine-sounding, transformer-coupled mic pre captures sources with an ultra-fast transient response, near-imperceptible self-noise, and minimal distortion. For added studio flexibility, the 80B includes a balanced line input and a front-panel hi-Z input, along with separate microphone and line-level controls. You also get phantom power, highpass and lowpass filters, and a polarity reverse. An easy-to-read VU meter rounds out this outstanding, pro-studio-level microphone preamplifier. Any studio that wants to bolster its analog front end will be blown away by the 80B 500 Series module — it straight-up nails the legendary sonic character of a Trident Series 80B console.

Lundahl transformer-coupled design

Armed with a Lundahl output transformer and electronically balanced line inputs, the 80B module delivers a sound that harkens back to Trident's fabled '80s-era recording consoles. This mic preamp can withstand levels from -60dBu to as high as +15dBu without breaking a sweat — no pad required. It boasts a frequency response that extends above 40kHz, enabling you to coax every detail out of your high-dollar condenser microphones. Moreover, the 80B's high-gain, low-noise design enables you to use it with dynamic and passive ribbon mics without raising the noise floor.

Chock-full of professional features

Here at Sweetwater, we're shocked at how much functionality Trident packed into a single 500 Series module. You get +48V phantom power for your condenser microphones, along with highpass and lowpass filters that make short work of extraneous high- and low-frequency noise. The Trident Audio Developments 80B includes independent gain knobs for mic and line-level signals, as well as a front-panel hi-Z input for instruments and other high-impedance sources. A polarity reverse button and an 8-segment LED output meter give you even more functionality.
