Tascam MU-1000
The optional meter bridge for Tascam's DM-3200 - the accessory that turns a working console into a monitoring console.
Overview
The MU-1000 is not a mixer, not a recorder, and does nothing on its own. It is the optional meter bridge for the Tascam DM-3200 digital mixing console. It gives the operator a dedicated, always-visible level display, so the console's LCD doesn't have to handle the metering. Tascam built the DM-3200 to be fully operable without the bridge. The console works fine if the MU-1000 is never installed. That tells you how Tascam positioned it: a convenience for the engineer who wanted meters at eye level instead of buried in a menu.
The DM-3200 is the console the MU-1000 attaches to. The period press documents it as a 48-channel digital mixer with 16 faders, capable of operating at up to 96 kHz. Pro Audio Review (October 2007, p.36) described it as a digital console offering strong value for 96 kHz operation. It also noted that the console carries 48 channels of audio with DAW control and multichannel computer interface capability via the optional IF-FW/DM FireWire card. The same review put the price at \$3,799 in its "Fast Facts" sidebar, while the body copy cited \$3,000. Anyone trying to date a receipt should keep that discrepancy in mind.
The bridge connects to the DM-3200 through a dedicated connection on the console. It provides the physical meter display that the console's front panel otherwise leaves to the LCD. Tascam's documentation for the DM-3200 lists "a connection for the optional MU-1000 meter bridge" among the console's rear-panel facilities, alongside the TDIF, ADAT optical, AES, S/PDIF, USB, Word Clock, MIDI, SMPTE, Sony 9-pin, and footswitch connections. That single line is the most concrete description of the MU-1000's role in the source material. It is an accessory port, and the bridge plugs into it.
Mix (October 2006, p.174) reviewed the DM-3200 and described it as a 48-channel audio mixer and DAW controller that, with the addition of the IF-FW/DM FireWire card, could serve as the audio interface for a DAW. The review's headline called out "Sixteen Motorized Touch Faders With FireWire Option" — and notably, the meter bridge does not appear in that headline. The MU-1000 was the kind of option that reviewers mentioned in passing, if at all, because the console was the story. Pro Audio Review (October 2007, p.36) was more explicit about the bridge's optional status, noting that the meter bridge was "available for those that desire it, but the console is fully operable without it."
The MU-1000 is a meter bridge. It does not change the sound of the DM-3200, does not add channels, and does not add processing. It adds meters. For a project studio running a DM-3200 as the center of a DAW rig, that is a real ergonomic improvement, since the meters can be seen across the room while tracking. It is not a transformative upgrade, and Tascam never pretended otherwise.
A used MU-1000 is a display accessory that is only useful if you already own a DM-3200. It has no standalone function, no inputs or outputs of its own beyond the console connection, and no value to anyone running a different console. Tascam sold the DM-3200 with the bridge as an option rather than standard equipment, so many used consoles come to market without one. A DM-3200 with the MU-1000 attached is a more complete package than one without. Whether that is worth a premium is a judgment call, since the bridge does not affect the console's operation, only the operator's view of it.
