Handling Precautions; Installation Precautionss; Nomenclature And Functions; [Front] - Toa MM-700F Operating Instructions Manual

• Class­D amplifier has a lot of protection features against over current, high temperature and short circuit
of speaker lines at each output channel individually. (*)
• Power supply with Power Factor Correction for reduced power consumption and world­wide operating
range. (*)
(*) MA­725F only

5. HANDLING PRECAUTIONS

• Keep the input cable away from the output cable. If installed close to each other, oscillation could occur.
• To avoid unit failures, never connect outputs of 2 or more channels in parallel.
• Only connect speakers with an impedance equal to or greater than those specified. Connecting speakers
with a smaller impedance than specified could cause damage to the unit.
• Install the unit in locations where the temperature is between –10°C and +40°C (14°F and 104°F) and the
moisture is less than 90%RH (no dew condensation must be formed).
• To clean, be sure to first turn off this unit's power switch, then wipe with a dry cloth. When the unit gets
very dirty, use a cloth damped in a neutral cleanser. Never use benzene, thinner, alcohol, or
chemically­treated cleaning cloth because such volatile liquids could deform or discolor the unit.
6. INSTALLATION PRECAUTIONS
• When mounting the unit in an equipment rack, the inside of the rack must be sufficiently ventilated.
To achieve sufficient ventilation, remove all panels on the rear of the rack.
• When mounting the unit in the rack, also mount a Perforated Panel larger than 1U in size
(1) at the top and the bottom of the rack, and
(2) above and below every 5 units.
* 1U size = 44.5 mm or 1.75" (reference size)
