Details
Controls: Variable mic input impedance, switchable plate voltage, large VU meters, backlit function switches, mid/side miking support, separate analog and digital output level controls, digital level LED meters (avg/peak), rotary encoder for sample-rate selection
I/O: Analog: XLR mic inputs x2 (rear), 1/4" instrument inputs x2 (front, auto-selecting), XLR analog outputs x2. Digital: AES/EBU out, S/PDIF out, ADAT optical I/O (switch-selectable between S/PDIF and ADAT modes), word clock input and thru.
Notes: Task instructions specify digital_control stays blank (no digital recall layer, this is a manual-knob tube preamp with a separate AD converter/digital output stage) -- flagging that per instructions. dsp left blank: the unit performs A/D conversion and sample-rate handling but this is not framed by ART as internal DSP processing of the audio path, so left blank rather than guessed as 'true'. phantom_power explicitly checked on the manufacturer page and NOT mentioned anywhere (unusual for a mic preamp with XLR inputs, but per the no-guessing rule this is left blank rather than assumed true). price_usd ($152.15) is a 'starting from' aggregate figure seen consistently across Reverb/Equipboard search results, condition and dealer unclear (likely a used-market floor since Sweetwater no longer stocks this discontinued unit) -- treat as low-confidence approximate/used-market price, not a list price. country_of_manufacture and year_intro not stated on page.
