IV. OUTPUTS Four “touch-proof” binding posts—one pair per chan- nel—on the rear panel allow speaker cable connections to the amplifier outputs. The special design allows con- nection of large diameter speaker cable while reducing shock hazard due to the high output power of MXa amplifiers.
• The thermal management system on an MXa Series amplifier features either a two- speed fan (MX 1000a, MX 1500a, and MX 2000a) or a variable-speed fan (MX 3000a) that modulates the cooling air flow over the heatsinks in response to the cooling needs.
2400 watts (@ 8 ohms) for the MX 3000a, 1300 watts (@ 8 ohms) for the MX 2000a, 1000 watts (@ 8 ohms) for the MX 1500a, and 700 watts (@ 8 ohms) for the MX 1000a. VORSICHT BEIM ÜBERBRÜCKTEN MONO-MODUS: Zwischen den überbrückten Terminals eines MXa-...

Temperature sensors on the channel heatsinks and the power transformers are part of the thermal management circuitry. On the MX 1000a, MX 1500a, and MX 2000a, the temperature sensors govern whether the dual-speed fan should run at low or high speed. Below 55˚ C, the fan runs at low speed;...
