I have a like-new Solstice that I haven't been using for some time so it is time to let it go. It is very versatile with two channels and 4 independent inputs. I was using it to mix a mic with a pickup on my instrument but with so many options you could use this unit as your whole PA or a mixer for recording. It comes with the AC adapter and the mic stand adapter.
$250 plus shipping. *SOLD*
From the DTAR website:
Solstice is a high quality two channel preamp mixer that blends virtually any type of sound source. The low-noise hybrid circuitry and internally adjustable gain from 0 to 24db make it suitable for both live and studio use. Solstice is the perfect solution for musicians looking to live-mix up to four sources such as piezo pickups, magnetic pickups, standard mics, and high output condenser mics.
* 1/4” and XLR inputs on each channel: Allows either a microphone or pickup input on either channel
* Balanced XLR mic input with true gain control for optimum headroom and lowest noise: Very low noise and high common mode rejection ratio. Utilizes discrete hybrid circuitry as in high end mixing consoles
* Full 3 way level / clip indicator: Helps set optimum gain for best headroom and signal to noise ratio
* Phase reverse switch on each channel: Helps control acoustic feedback
* Channel effects loop with send and return jacks: Can be used as independent signal output or as insertion point for external signal
* Mute switch: Allows complete shut off of rig
* Tuner output (unaffected by mute switch): Allows quiet tuning
* Stereo input jack: Allows access to both channels with one stereo cable
* External wall mount power supply: Allows AC operation for best performance
* High quality components: Extremely low noise and distortion, audiophile quality sound
* Mic stand adapter available as an option: Useful for on-stage applications that use a microphone stand. Allows the performer to have full access to the front panel while facing the audience
