AC Mains and Grounding (Earthing) Considerations

Each MMR-8 requires one AC mains connection. A standard six-foot (1.83 Meter) power cordset is included with each MMR-8, wired for the USA standard. A six-foot (1.83 Meter) AC Mains cordset for use in Europe, proper for the country of use will be supplied by your TASCAM dealer. The AC mains outlet must be capable of delivering 230 watts (2 amps) for each MMR-8 in the system. The main power supply has a 115/230 VAC switch on the back of the unit. This switch should be set to match the facility power level.

An unswitched female IEC convenience outlet is located on the rear panel of each MMR-8. In normal use there is no connection to this outlet, although other electronics equipment using IEC plugs, and drawing less than 120 watts total, can be connected to this outlet using the appropriate male-to-female IEC power cord (like those used with computer monitors).

A facility-wide UPS system is recommended for protecting the MMR-8, and all your audio equipment, from power line spikes, surges, brownouts, and line failure. If a facility-wide UPS is not available, each MMR-8 should be connected to a home computer-type surge/spike protection system (of 250 watts minimum) which is then plugged into an isolated ground AC outlet.

Caution: Grounding (Earthing)

Do not defeat the AC cord U-ground as this will present a potentially dangerous operator hazard. Using an isolated ground outlet ensures the proper chassis grounding to the mains “power company” ground. Using only isolated ground outlets throughout a facility will prevent audio ground loops caused by AC outlets with different ground potentials. A Ground Stud is provided on the back panel for chassis grounding of the MMR-8.

Audio Cables

Analog I/O Cables All analog input and output on the MMR-8 is done through a pair of 25-pin D-sub connectors which are pin-compatible with the Tascam DA-88 connector. Tascam DA-88 DB-25 to XLR cables, with either male (output) or female (input) XLR connectors, are available from your authorized Tascam dealer.

Digital I/O Cables Analog I/O cables can be adapted for use as Digital I/O cables using 4 XLR gender adapters. This arrangement provides four stereo AES/EBU digital inputs and four stereo AES/EBU digital outputs using a standard DA-88 cable.
