JBL MPC 300 Professional Stereo Power Amplifier 300W 4 ohm Made In USA

  

JBL MPC 300 Professional 2 Channel Stereo Power Amplifier with Manual Copy Made In USA. Blemishes include a slight stain mark on the case top and a minor scuff on the fronts bottom edge. Please see the pictures provided.

To ensure optimal performance and avoid potential damage, this product is best suited for individuals with experience in amplifier use and sound system configuration. The MPC Series from JBL is a line of professional power amplifiers specifically designed for contracting applications. MPC amplifiers feature balanced inputs, connected via a Euro-style 7-terminal detachable header. Each channel has its own power transformer secondary to provide maximum audio separation (minimum sound leakage) between the two channels, minimizing interaction that can otherwise occur on amplifiers with a common power supply. The MPC200, 200T, 300 & 300T utilize complementary Class AB linear output circuitry.

The MPC Series is engineered for stability and exceptional reliability, with protection for open or short circuits and mismatched (under impedance) loads. Protection is also built-in for ultrasonic, infrasonic (subsonic) and RF. To protect the loudspeakers the outputs mute during turn-on and turn-off and also in the event of a DC load fault. All protection circuitry automatically resets to normal when conditions assure safe operation. Every MPC amplifier features a large diameter two-speed fan and massive extruded aluminum heat sinks.

The output devices couple directly to the heat sink. This provides better cooling of the output devices while eliminating problematic insulating wafers that are an integral part of most other amplifier designs. Forced air cooling in a back to-front direction provides for more effective cooling, preventing problems that otherwise occur from a continual heat build-up inside the equipment rack, which occurs in amplifiers with front-to-back or side-to-side flow schemes. These design factors allow the MPC amplifi ers to work in high duty-cycle instances when many other professional amplifiers cannot. The amplifier should be supported at all four corners, especially if it is in a portable rack. The flow-through cooling scheme allows you to rack-mount the amplifiers on top of the other, with no clearance necessary in between. Make sure that the direct weight of the back of the amplifier is supported from the bottom of the rack. The MPC300 is 3 rack spaces high. //- Thank you for browsing, feel free to contact me with any questions or concerns.
