The ASK-4 502-TLM-W Audio Monitoring Kit from Louroe Electronics is a 2-zone audio monitoring system with 2-way talk / listen capability. This kit consists of 2 TLM-W 2-Way Speaker / Microphones, an AP-2TB Audio Base Station, and an AC Adapter.

The AP-2TB Audio Monitoring Base Station is a 2-zone unit designed to achieve 2-way listen / talkback functionality. As a complete system using Louroe speaker / microphone units, either zone can be monitored by manually pressing the button switch for the desired zone. It has an input / output interface to connect to a DVR / VCR for recording and playback. It contains a 4” (10.16cm) speaker for monitoring live audio and playback from a DVR / VCR, and a built-in microphone for providing talkback to the remote zone. It is suitable for use in observation rooms, classrooms, storage facilities, gated entrances, building peripherals, warehouses, sleep disorder centers, or anyplace where CCTV cameras are installed.

The TLM-W Speaker / Microphone is a 2-way unit with an electret condenser microphone and a 2.5” (6.35cm) speaker, all within a single housing. As part of a Louroe audio system, it provides 2-way communication between the remote area and the audio receiving device (Louroe Base Station, etc). A plastic back box is provided with each speaker/microphone unit for surface mounting to a wall.

Note: 4-conductor cable consisting of 2 conductors shielded, 20 gauge with a 22 gauge drain (for microphone connection) and 2 conductors unshielded, 18 gauge (for speaker connection).
When this equipment is used as part of an audio monitoring system, the law requires that the public be given notice of AUDIO MONITORING ON THE PREMISES. A decal notice is included with each microphone shipped.
