Cooling system. Two Φ80 fans auto speed high low adjustment according to temperature, thermostat set at 55 degreest.

Amplifier Protection: short circuit protection, subsonic frequency protection, RF protection, clip protection,soft start equipment,overheat and voltage protection.

Overload Protection: no thumps or pops are heard with turn-on /turn-off of speaker System overload automatic power-cut.Filter setting prevents peak overload of woofer.Limiting setting prevents high frequency clip wave and thus avoid teeter damage.

Output circuit types: efficient complementary linear output:

Power voltage: 100 V 120 V select switch, 220 V 240V select switch, 50Hz/60Hz, other voltage available if customised.

Dimension: 88mm × 483mm × 480mm

Weight: 26KG

Note: MT series powers all models of our loudspeakers , preferable for C-MARK AT-series loudspeaker or speaker array.MT1500 fits small size speakers,or drive of tweeter after scaledown,making more pure and more rich sounds.

For extended periods of continual use of the amplifier, it is suggested that load impedance of each channel no less than 4Ω,and for bridged patttern,no less than 8Ω.
