Important Safety Instructions
ATTENTION:
- Terminals marked with this symbol carry electrical current of sufficient magnitude to constitute risk of electric shock. Use only high-quality professional speaker cables with ¼” TS or twist-locking plugs pre-installed. All other installation or modification should be performed only by qualified personnel.
- This symbol, wherever it appears, alerts you to the presence of uninsulated
dangerous voltage inside the enclosure – voltage that may be sufficient to constitute a risk of shock.
Caution:
- This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual.
- To reduce the risk of electric shock, do not remove the top cover (or the rear section). No user serviceable parts inside. Refer servicing to qualified personnel.

Servicing is required when the apparatus has been damaged in any way, such as power supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
- The apparatus shall be connected to a MAINS socket outlet with a protective earthing connection.
- Where the MAINS plug or an appliance coupler is used as the disconnect device, the disconnect device shall remain readily operable.
- Correct disposal of this product: This symbol indicates that this product must not be disposed of with household waste, according to the WEEE Directive (2012/19/EU) and your national law. This product should be taken to a collection center licensed for the recycling of waste electrical and electronic equipment (EEE).

76-KT Hook-up
Step 1: Hook-Up
Step 2: Controls
- Adjust the INPUT knob to simultaneously set the signal level entering the unit and also set the compressor threshold. Turning the knob clockwise will result in more compression.
- The OUTPUT knob sets the overall level sent from the unit.
- Use the ATTACK knob to adjust the amount of time it takes for the compressor to respond to audio that exceeds the threshold. The response time is slow when set fully counterclockwise and faster as it is turned clockwise.
- The RELEASE knob adjusts how long the compressor remains engaged after the incoming audio falls below the threshold. The response time is slow when set fully counterclockwise and faster as it is turned clockwise.
- The RATIO buttons determine the amount of gain reduction. The lowest setting of 4:1 results in fairly mild compression, while 8:1 yields heavier compression. The 12:1 and 20:1 settings act as a limiter instead of a compressor. Higher settings also increase the threshold automatically. An extreme effect can be achieved by pressing all 4 RATIO buttons in simultaneously.
- The VU METER displays either the amount of gain reduction or the output level, depending on which operation is selected.
- The METER BUTTONS select whether the VU meter displays the amount of gain reduction (GR) or displays the output level. A meter reading of 0 corresponds to an output level of +4, +6 or +8 dBm, depending which button is engaged.
- The POWER switch turns the unit on and off.
- OUTPUTS are available as balanced 1/4″ and XLR connectors.
- INPUTS are available as balanced 1/4″ and locking XLR connectors.
- Engage the PAD switch to reduce the input sensitivity by 20 dB for use with hot signals.
- The small meter adjustment pot allows the meter to be calibrated. See the ‘Getting Started’ section for details.
76-KT Getting Started
Step 3: Getting started
- Install the 76-KT in a rack and connect the input and output jacks to your equipment. Using a patchbay may allow the most flexible routing for a variety of applications.
- After the power cable has been connected to a mains outlet or power strip and audio cables have been connected to your equipment, turn the power switch on.
- Power on your other equipment. Be sure to turn the speakers on last.
- Select the +4 METER button to begin. This allows the output level to be displayed in the meter.
- Start with the INPUT and OUTPUT knobs at the 12:00 position.
- Turn the RELEASE knob fully counterclockwise and set the ATTACK at the center 12:00 position.
- Raise the level of your source audio so that the 76-KT’s meter periodically reaches 0. No audible distortion should be heard.
- Press the 4 RATIO button for lighter compression or 8 for a more aggressive squeeze. For limiting, press the 12 or 20 button.
- Adjust the INPUT knob to vary the compressor’s threshold, and compensate changes in level with the OUTPUT knob.
- Press the GR METER button to monitor the amount of gain reduction.
- The unit has a special “all-buttons” mode available where all 4 RATIO buttons are depressed simultaneously for extreme effects.
Meter Calibration
The 76-KT offers a convenient rear panel pot to calibrate the VU meter.
- Disconnect any audio cables from the rear panel, then turn the unit on.
- Press the “GR” METER BUTTON.
- Adjust the calibration pot until the meter reads 0 dB.
