Front Panel
The single volume control adjusts the level delivered to both left and right earpieces. The power LED indicates operational status. Although 1/4" TRS and 3.5mm TRS headphone jacks are included for convenience, only one jack should be used at a time.

Rear Panel
Three paralleled looping jacks accept unbalanced stereo line level input signals. There are two 1/4" TRS jacks and one 3.5mm TRS jack. This arrangement allows "daisy chaining" the signal to as many as 25 units with a single feed line. The left signal is on the tip and the right signal is on the ring. The sleeve is the common connection for both channels. The 2.1mm power input jack is for connection to the 24 Volt DC 200mA included power supply.
