Description

DigiTech positioned the JamMan Vocal XT (JMVXT-U) as a compact looper designed specifically for vocalists, extending the JamMan looper family beyond guitar-oriented units. It accepted XLR microphone signals directly, processed them through a built-in dbx microphone preamplifier, and returned the signal via a balanced XLR output — making it a self-contained mic preamp and looper in a single small unit.

The preamp section offered up to +40 dB of mic-level gain with 45V phantom power for condenser microphones. The unit recorded at 46.8 kHz/24-bit with a frequency response of +0/−3 dB across 20–20 kHz and a signal-to-noise ratio of −100 dB. Maximum individual loop time was 10 minutes in stereo. The JamSync feature allowed the JMVXT-U to synchronize automatically with compatible JamMan units — specifically the Vocal XT, JamMan Express XT, and JamMan Solo XT — enabling independently recorded but tempo-locked loops across multiple devices. A Silent Clear function allowed a recorded phrase to be erased without requiring playback first. The unit drew fewer than 200 mA typical and was powered by the PS0913DC-01 supply, accepting 100–240 VAC worldwide input and outputting 9 VDC at 1.3 A.

Owners requiring service, calibration, or replacement parts — including the PS0913DC-01 power supply or XLR connector components — should consult a qualified audio technician familiar with signal-chain hardware of this type.

From the people who own them

Nothing in The Vault is for sale. These records exist so the instruments stay documented after the manufacturer moves on — and the most useful part of that record is what owners add to it.

Put yours on the record.

The catalog shot showed one finish, under one light, a long time ago. Yours has been played. Photos from owners are what the next person finds when they are trying to identify a part, match a finish, or work out whether the one they just bought is really what the seller said it was.

What do you know about this one?

Specs only go so far. What actually fits, what breaks first, what the factory got right and what everyone ends up changing — that lives with the people who own them, not in a datasheet. Post what you know and it stays on this page for whoever comes looking next.
