The Model AP-4TB-RM and AP-8TB-RM are four and eight zone audio monitoring base stations designed for two-way listen/talkback. As a complete system, any zone can be monitored, by pressing the button switch for the desired zone. The units contain a 3” built-in speaker for monitoring audio and a built-in microphone for talking back to the remote zone. Each zone has an audio output jack (RCA) for connection to a DVR with multiple audio inputs. All Louroe Speaker/Microphones (Model TLI, TLM, TLMC, TLSP, and TLO) are compatible with the AP-4TB or AP-8TB
