Phoenix Audio Ascent One Overview

The Ascent One Class-A Mono Microphone Pre-Amplifier/DI from Phoenix Audio takes a modern approach to Class-A circuit design and delivers a wide range of tones without sacrificing the beloved vibe of true Class-A design. It can be used with all microphones including ribbons and dynamic mics to drive the output stage for a vast range of pure Class-A tones—from bold clarity to vintage warmth—in broadcast TV or recording studio applications.

Featuring a -15 dB input pad, LED gain metering, and push buttons for Hi-Pass Filter, Phase Reverse, and switchable 48V phantom power, the Ascent One microphone preamplifier offers a frequency response of 20 Hz to 20 kHz. Other features include XLR and TRS 1/4" DI input connectors, and XLR and TRS 1/4" output jacks on the rear panel. Additionally, the Vari-Filter control allows you to control and shape tones of all types.

Versatile, Modern Class-A Mic Preamp/DI
The Phoenix Ascent Mic Preamp/DIs take a modern approach to Class-A circuit design that delivers a wide range of tones without sacrificing the beloved vibe of true Class-A design. The Ascent circuit can go from ultraclean sounds suitable for audiophile recordings all the way to the warm, saturated tones reminiscent of the UK's most heralded vintage designs.
Hi-Fi Transformerless Mic Input Stage
The mic preamp's electronically balanced transformerless mic input circuit delivers fast transients and the full frequency spectrum (from sub-bass to the highest air band), while still delivering the full, warm, and smooth characteristics that make engineers love Class-A mic preamps. Boldly outperforming transformer-based designs in both the frequency response and the slew rate, the Ascent delivers articulate, punchy, and full-bodied input signals, allowing you to drive the output stage for a vast range of pure Class-A tones, from bold clarity to vintage warmth and everything in-between.
Transformer-Balanced Output Stage
The DB694 output transformer is coupled to Phoenix's proprietary, fully discrete DSOP-2 output amplifier. The DSOP-2 is a direct descendent of the venerable TF1 amp, which Phoenix's head-designer, David Rees, developed as an upgrade for vintage Neve modules. Going beyond the TF1, the DSOP2 is the pinnacle of Class-A output circuit design, offering up a smooth transition from ultraclean to beautifully saturated tones.
Ultra-High Impedance DI Circuit
The Ascent mic pre series includes very high input impedance (10 MOhm) DI circuits, remarkably featuring no FETs, on every channel. This design means that guitar and bass pickups are not loaded, allowing the natural sound of both modern and vintage instruments to shine and enhance the sound, and sparkle and growl as if they were plugged into your favorite amp. Synths, drum machines, and even laptops can likewise be sweetened by the Ascent's DI.
Easy and Intuitive in The Studio
Working with a clean, robust, electronically-balanced input signal, the Ascent Mic Preamp/DI makes dialing in your exact sound easy, intuitive, and quick. By working the familiar stepped input gain control (up to 70 dB alone) and the -30 dB pad against the variable output fader (which provides an additional 10dB of gain), you can dial in your preferred tones without having to consider an overly complex gain architecture. It's all about driving the versatile DSOP-2 output stage to your exacting tastes, whatever they may be in any given moment.
Vari-Filter Control
Powerful variable high-pass filter from 70 Hz to 400 Hz giving you the ability to control and shape tones of all types.
