Page 6: Outputs
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. -
Page 7: Troubleshooting
• 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. -
