Usage Features

Input Selection: Users can select between XLR (balanced) and RCA (unbalanced) inputs using the input select button located on the back panel.

Standby Function: The device includes a standby feature that can be toggled on or off via a button on the back panel. If the standby function is enabled and no signal is detected for 120 minutes, the Gorilla will automatically turn off to conserve power.

Driver Placement: For optimal listening, the tweeters of the Gorilla loudspeakers should be positioned inside the user's listening point.

Safety Precautions:

Operates at mains voltage and carries hazardous voltages.
Avoid exposure to rain, water, or moisture to prevent fire or electric shock.
Do not place near heat sources like amplifiers.
Ensure electrical power is off before connecting or disconnecting cables.
Avoid direct sunlight.
The product should not be disposed of with household waste due to potentially hazardous substances. Contact local authorities for recycling information.

Protection Circuits: The Gorilla incorporates four protection circuits:

Thermal Protection: If the maximum temperature is reached, amplifiers switch off, and a red protection LED on the front illuminates.
Electrical Failure/High Frequency Signal Protection: In case of a critical electrical failure or high-frequency signal (e.g., microphone feedback), amplifiers shut down immediately, and the red protection LED activates.
- Recovery: Unplug the power cord, wait approximately 3 minutes for the back panel to cool and the red light to turn off, then plug the power cord back in and power on the Gorilla.
Clipping Warning: A blinking red LED on the front indicates that the amplifiers are clipping. Users should lower the input signal until the blinking stops.
- Clipping Protection: Excessive clipping will cause the amplifiers to shut down to protect the gear.
- Recovery: Similar to other protection events, unplug the power cord, wait about 3 minutes for the red light to turn off, then plug in and power on.

Maintenance Features

Service and Warranty:

Modifications by unauthorized personnel will void the warranty.
The device comes with a two-year limited warranty from the original purchase date, covering defects due to faulty workmanship or materials under normal use.

Troubleshooting:

No Power: Check the power outlet. If the internal fuse is blown (not user replaceable), contact Telegrapher Loudspeakers for service.
No Sound:
- A protection circuit might be triggered (e.g., module overheated). Try cycling the mains power.
- Check the source signal.
- Check the cables.

General Usage Advice:

Do not leave loudspeakers on at night unmonitored.
Turn off after use.

Support: Telegrapher Loudspeakers offers support through their website, where users can find manuals, datasheets, and contact them via a form for any questions.
