The PTA-16 connects easily to many base station radios. Depending on the actual number of parallel units and line length / condition, a telco line amp may be required to offset loading
Midian Electronics PTA-16 Parallel Tone Remote Adaptor
Adaptor Mode: Midian's PTA-16 allows for control of up to 16 radios in parallel on one dedicated line by a tone remote controller. The 16 radios can be addressed individually (F1-F16) or in simulcast (F17). The radio's COR causes the PTA-16 to send 2175 Hz followed by the radio's unique function tone to identify the radio to the tone remote controller, which is automatically displayed on the controller's LCD. Additionally, the PTA-16 can also change channels on each radio using DTMF signaling from the tone remote controller.
Controller Mode: The PTA-16 can also operate as a tone remote controller. When connected to an audio source, grounding the COR Input will cause the PTA-16 to encode the high-level 2175 Hz guard tone, followed by the programmed function tone (F1-F16) and then followed by the continuous low-level 2175 Hz guard tone and the audio from the remote audio source in order to cause a tone remote adaptor such as Midian's TTC-1 or TTC-2 to key the base station. Likewise audio can be received from the tone remote adaptor by the PTA-16.
Applications
In adaptor mode, the PTA-16 is useful in subways, railroads, etc. In control mode, the PTA-16 can be used to connect a remotely controlled paging terminal or other audio source to a base station.
Features:
- 2-wire or 4-wire (option) capability
- Control up to 16 radios in parallel
- DTMF decode for channel change
- Simulcast capability
- 3 year warranty
Midian's PTA-16 can be used with Midian's TRC series tone remote controllers or another manufacturer's tone remote controller that uses EIA and industry standard F1-F16 function tones and Midian's F17 function tone. The PTA-16 connects easily to many base station radios. Depending on the actual number of parallel units and line length/condition, a telco line amp may be required to offset loading.
