Provisions to handle up to 8 head table positions

The FSR MLH-8 Head table speaker operation has provisions to handle up to 8 head table positions, meaning an installation could have a single HT-8 module. It is optional and is contained on a PC board. This board mounts on a TRAC-BRAC, usually adjacent to the audio power amplifiers. There are two terminals for each speaker output and two terminals for the amplifier input. However, only one side of the line is switched. The other set of terminals are for convenience. The plug-in wall transformer powers the HTBC (head table break out card), which in turn powers the HT-8 relay cards.

Each HT-8 module contains relays for eight head table locations. Up to four HT-8 cards can be implemented per system. The monitor relay card is associated with the Monitor VU panel and provides the actual speaker switching. Both sides of the speaker line are switched. A plug-in wall transformer powers the card. The MLH-8 Head table speaker operation has a 3-year warranty included.
