Dynasty ProAudio PX2 Multi-Source Stereo Preamplifier with Bluetooth 5.3 + USB DAC Interface built-in. Simply connect those sources and more using the RCA and S/PDIF inputs on the back panel — or the front-panel 1/4" mic input — then use the RCA output to connect to your amplifier.
TheAPI 3124+ Mic/Line Preamplifier is a discrete, high quality, compact, 4-channel mic/line preamp, plus D.I. Another feature of the 3124+ is that it can provide up to 65 dB of gain to an output clip level of +28 dBu.
The classic Neve 1073 wrote the book on characterful mic preamplification, so in designing their Pre-73 MKIII mic pre, Golden Age aimed high. Given its mild pricetag, it's amazing how well they succeeded. The single-channel Pre-73 MKIII is versatile, with 80dB of gain that lets you easily mic subdued sources with passive ribbons. Cranking the main gain stage imbues your tracks with tasty vintage-style coloration. Also onboard: phantom power, a broad gain-range DI, flexible I/O, switchable impedance, and an LED output level meter, all in a robust half-rack chassis. If you want a characterful pre with punch, Sweetwater recommends the Golden Age Pre-73 MKIII.
Frequency response is 10-30,000Hz. Battery life is about 180+ hours. On the rear of preamp are two 1/4" jacks (input and output). The output jack also doubles as battery switch, when unplugged it disconnects the battery when not in use.
