THRU INPUT

1

This is where you connect AC power and your

signal to the loudspeaker and make adjustments to the frequency response of the speaker to match the loudspeaker’s location and your room’s environment.

1. INPUT

This is a female XLR-type connector that accepts a balanced mic or line-level signal from a mixing console or other signal source. For small gigs, simply connect a microphone directly and adjust the LEVEL control [3] accordingly.

2. THRU

This is a male XLR-type connector that produces exactly the same signal that is connected to the input jack. Use it to daisy-chain several TH-12As together off the same signal source.

3. LEVEL

The LEVEL control adjusts the overall signal level at the input to the built-in power amplifiers. It ranges from Off () to MAX (maximum gain), with unity gain at the center position (12 o’clock).

•The TH-12A is designed to operate with a +4 dBu signal when the LEVEL control is at the U (center) position.

•The TH-12A can accept up to a +20 dBu signal by turning down the LEVEL control accordingly. Turning the LEVEL past unity will provide enough gain to connect a microphone directly.

•NEVER connect the output of an amplifier directly to the input of the TH-12A. This could damage the active input circuitry of the loudspeaker.
