Phoenix Audio DRS-1R-500
500 Series Mono Class A Microphone Pre-Amplifier/DI
The Phoenix Audio DRS-1R-500 is a mono pre amp and DI for the API 500 series format, and was designed to be identical in terms of features and sonics as the ever popular DRS1 but in this much smaller footprint. The unit runs at 24v thanks due to the special power supply built into the unit so it offers no sonic sacrifices whilst still maintaining a very low current use needed for the API format and is well within its API VPR limits.
Phoenix Audio DRS-1R-500 Features:
- Phoenix Audio's unique Class A, transformerless, true-balanced mic input stage
- Phoenix Audio's transformer-balanced DSOP-2 Class-A discrete output stage with custom wound DB694 output transformer
- Wired with PTFE silver plated military grade cable
- -30dB input pad
- High Pass Filter: -6dB per octave @ 120Hz
- LED Gain Metering
- Push buttons: Hi-Pass, 48v, Phase Reverse, Switchable 48V phantom power on push-button switch
- High Pass Filter on Push-button Switch (Roll-off -6dB per octave @ 120Hz)
- Phase Reverse on Push-Button Switch
- Mic Pre Gain Range: -30 to -70 in 5dB steps With 10dB more available on the ouput fader.
- Output = +26dBu @ 1kHz, Noise = -90dB @ 20Hz to 20kHz.
- Frequency Response Mic Input Stage: -0.4dB @ 40Hz, -0.3dB @ 25kHz
- Frequency response Class A (DSOP-2) output stage: 20Hz to 20kHz +- 0.5dB, Maximum
- 24v built PSU so you can feel the sound of the 'true' unit and not be limited by the limitations of running at 16v which is the standard Lunchbox voltage.
Hi-Fi Transformerless Mic Input Stage
Phoenix Audio's exclusive 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 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. With a very high mic impedance of 10K, it is the perfect companion for ribbon mics and dynamics mic that often need specialist mic pre amps, the Shure SM7B particularly shines.
Legendary Transformer-Balanced Output Stage
Phoenix Audio's custom-wound 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 ultra-clean to beautifully saturated tones.
Ultra-High Impedance DI Circuit
The DRS1R-500 include very high input impedance DI circuits (10Mohm)—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 actually enhancing the sound, sparkle and growl as if they were plugged into your favorite amp. Synths, drum machines, and even laptops can likewise be sweetened by the DRS's DI.
Easy and Intuitive In The Studio
Because you're 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 70db alone) and the -30dB 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. Like so many other engineers, you'll find yourself reaching for the Ascent Mic Preamp/DI over and over again to reliably deliver a vast array of outstanding sounds for any instrument or voice you're recording.
