The IEDT6302L is a class D, dual channel, 600W Total, 70V power amplifier card used in the Titan T9160 multi-channel mainframe or in the IED T6400 two-card power amplifier mainframe. Any card may be placed in any slot in the mainframes without requiring any configuration settings to be made on the amplifier cards.

Class D operation combined with an integral switch-mode power supply offers many advantages, and the unique IED design makes full use of these benefits.

Switch-mode operation combined with high voltage power MOSFET devices make it possible to eliminate the heavy, costly, bulky transformers. The card contains no onboard attenuation controls. Attenuation is handled ahead of the power amplifier by the mainframe central processor. The power amplifier has built-in voltage limiting to protect the loudspeakers. In addition, a temperature sensor on the heatsink will automatically shut down an amplifier that becomes too hot to protect the electronics. When used with the IED T9160 mainframe, the amplifier status signals are monitored by the main control processor. Any failures are detected and reported to the IED supervision system to alert the user that service is required. When used in the IED T6400 mainframe, these status signals are presented at the back of the mainframe for monitoring by external devices such as the T9032MT or T9032LVIO collectors.

The amplifier card has LED indicators located on its front edge. A single green LED will illuminate to indicate that the amplifier is powered on. Each channel on the card also has a multi-color signal LED. It will illuminate green when input signal is present on the channel. This LED changes to yellow to indicate that the channel is clipping. A power switch is provided on the front of each card. It is recessed and requires a tool to operate in order to prevent any accidental switch operation. The switch allows an individual card to be powered down and removed or replaced without affecting any other cards installed in the same mainframe. Each card provides +24VDC through current limiting resistors to operate of the fans in the rear of
the mainframe.
