2-Channel Loudspeaker Protector Kit, 125x55mm

The 2-Channel Loudspeaker Protector Kit is an essential safeguard for any high-fidelity or professional audio system. This dual-channel protection unit prevents damaging power-on thumps from reaching your valuable stereo speakers and offers critical protection against dangerous DC components that can appear at the output of any connected amplifier. By eliminating these common threats, it ensures your speakers perform reliably and last longer.

At the heart of its operation is a precise switch-on delay of approximately 6 seconds. This delay allows your amplifier to stabilise fully after power-up before the audio signal is passed to the speakers, completely eliminating the loud 'thump' that can cause permanent damage to speaker cones and voice coils. Simultaneously, the unit continuously monitors for DC offset; if a DC voltage exceeding ±1V is detected on the speaker output, it instantly disconnects the speakers to prevent costly damage from this potentially destructive fault.

Built to handle demanding setups, the protector features a maximum input voltage rating of 200V peak-to-peak (71V RMS) and can switch currents of up to 10A per channel. Clear LED status indicators provide instant visual feedback: a 'wait' LED shows the switch-on delay is active, while an 'error' LED illuminates to alert you if a DC fault has been detected on the speaker output, allowing for quick troubleshooting.

The compact unit measures 125mm in width by 55mm in height, making it easy to integrate into existing audio racks, amplifier enclosures, or custom installations. Weighing 335 grams, it is a substantial yet manageable component. By incorporating this protector into your audio chain, you add a vital layer of defence, ensuring your investment in speakers and amplifiers is protected from some of the most common causes of failure.
