Four-Pack Preamp Microphones

This four-pack of high-gain preamp microphones adds audio capture to CCTV installations. Each unit includes a combined power and audio cable for straightforward wiring. The built-in IC preamplifier boosts low-level signals with low noise and automatic level adjustment. The kit is intended for installers who need synchronised sound recording across multiple camera positions.

Power Sharing and Signal Quality

The microphones accept 6-15 V DC and feature a power-in and power-out design that lets them share the camera’s supply. This arrangement reduces the number of separate power runs required on site. The onboard preamp raises the microphone’s output to a usable line level while keeping noise low. Automatic gain control helps maintain consistent levels without manual trimming.

Included Cables and Warning Decals

Every microphone ships with its own combined power and audio cable, so no extra loom is needed for the four channels. Free warning decals are also supplied to meet signage requirements for audio recording. The package contains only the microphones, cables and decals; no additional software or mounting hardware is provided. Installers should verify cable length suits each camera location before fitting.

Questions about this item

How do I connect the combined power and audio cable to share the camera's 6-15V DC supply?

Plug the cable into the microphone and the camera so the mic draws power from the same 6-15V DC source; the step people miss is confirming the camera can supply enough current for both devices.

What part will need replacement first on the built-in IC preamp microphone?

The electret capsule inside the preamp microphone is the wear item; it can lose sensitivity over time and will need swapping before the onboard IC or cable.

At what voltage does the line-level output start to clip during long recording sessions?

The line-level output clips if the shared 6-15V DC rail sags below the preamp's minimum operating voltage, so the supply headroom is the first limit under sustained use.
