Amplifier FAQ’s
Is the CA22CD a replacement product?
- Yes, the CA22CD-SC is the replacement product for the CA12CD-S. The CA12CD-S has been discontinued.
Are the new CA22 CD spares backward compatible (ex: battery pack, remote, etc.)?
- Poly will continue to sell the CA12CD-S spares, but the new spares are not backward compatible with CA12CD-S.
Versions
There are two primary versions of Model CA22CD: the single‐receive‐channel version, which is the direct replacement for Model CA12CD‐S, and the new dual‐receive‐channel version that Poly has created for voice systems that require dual‐channel headsets and adapters.
The single‐channel version is Model CA22CD‐SC and the dual‐channel version is Model CA22CD‐DC. Both of these variants are available with either DECT radios for regions like the European Union or DECT 6.0 (a.k.a. UPCS which is Unlicensed Personal Communications Services 1920‐ to 1930‐MHz band for use in North America) radios for use in the US, Canada, and Mexico.
CA22CD Compared to CA12CD‐S
The basic functionality of Model CA22CD is the same as Model CA12CD‐S, so users who are familiar with Model CA12CD‐S will be able to quickly get up‐and‐running with Model CA22CD. As can be seen in the figures below, we have taken this opportunity to refresh Model CA22CD’s industrial design. We have also added a couple of new features. They are:
- A USB port to enable use with PC‐based communications systems and training simulators.
- Dual‐receive‐channel capability: an optional dual‐receive‐channel remote and a second receive channel in the base. The new base automatically configures itself for either single‐ or dual‐channel operation depending upon which remote is subscribed to it.
Also, the PTT latency (time for a PTT button‐press to be communicated to the host equipment) has been greatly reduced and is now under 36 milliseconds.
An additional improvement is that encryption has been increased from 64 to 256 bits.
Functional Description
Model CA22CD is a cordless push‐to‐talk (PTT) headset adapter for providing wireless communications and PTT functionality to public‐safety‐dispatch, air‐traffic‐control, and other facilities that employ integrated telephone and radio communications.
Consisting of a base and a remote, Model CA22CD has a Quick Disconnect™ connector (for single‐channel systems) or a Switchcraft TA6FLX connector (for dual‐channel systems), a console‐interface cable, and an ac adapter. The single‐channel remote is compatible with all Poly H‐ and HW‐ series headsets, and the dual‐channel remote works with Poly’s dual‐channel headsets.
Model CA22CD’s audio link is intended to be on whenever the base and subscribed remote are powered up, so that the mic is always “hot.” The PTT button is used solely for “keying up” the host‐equipment’s communications radio, and it has no effect upon the status of the audio link.
The audio link stays active even when the remote is docked in the base, so that the remote can be used in emergency situations where there is no time to recharge a depleted battery. (Note that Poly recommends avoiding this scenario by regularly swapping batteries about every four hours.)
The base has two charging wells, send‐ and receive‐gain controls, status LEDs, and a ten‐foot (extended length) coil cord with a choice of connectors for customers with analog headset interfaces. For voice systems with USB interfaces, Model CA22CD can be ordered with a USB cable.
The charging wells accommodate the remote and a spare battery pack. The LEDs show the state of the battery charge and the status of the power, the link, and the PTT switch. The send (talk‐volume) controls consist of a four‐position slide switch on the underside of the base to emulate the outputs of different microphone types and talk‐volume fine‐adjust buttons on the top of the base.
The receive‐sensitivity controls consist of a four‐position slide switch on the underside of the base that selects among four different gain ranges and a receive‐sensitivity fine‐adjust rocker switch on the remote.
The typical PJ‐7 cable‐and‐connector assembly is wired with send on the connector tips, receive on the sleeves, and push‐to‐talk on the rings. When the user presses the PTT switch on the remote, a relay is closed in the base that places a short circuit across the PJ‐7 rings.
This short circuit “keys up” the communications console to which the Model CA22CD is connected and allows the user to transmit over the host equipment’s radio. Console‐interface cables with connectors other than the PJ‐7 work on the same principles, with send, receive, and PTT configured for compatibility with the host system.
For voice systems with USB interfaces, Model CA22CD enumerates as a composite audio device and game controller that uses standard operating‐system drivers. The PTT button appears to the host system as Button 1 of a single‐button game controller. (The host‐system software must be capable of reading and using this button press.)
In addition to the PTT switch, the remote has an on‐off switch with incorporated LED, a metal belt clip, a receive‐sensitivity fine‐adjust control, and a twelve‐inch cable terminated in a either a Poly Quick Disconnect™ connector for single‐channel systems or a Switchcraft TA6FLX connector for dual‐channel systems.
The technology of Model CA22CD, including the new radio chipset and surrounding architecture, is based on field‐proven DECT products that are in use by the thousands throughout the world.
Like Model CA12CD‐S, the new Model CA22CD is a medium‐range system that uses the DECT 6.0 (Digital Enhanced Cordless Telecommunications) standard to operate in the Unlicensed Personal Communications Services (UPCS) 1920‐ to 1930‐MHz band for use in North America.
For use in regions such as the European Union and Australia, Model CA22CD is configurable through production‐line EEPROM settings to operate in the DECT frequency band of 1880 to 1900 MHz. The DECT protocol is used for its power efficiency, which allows extended operation from a relatively small battery pack.
The Model CA22CD variants that are sold outside of North America use ten carrier frequencies, which accommodate a total of 120 duplex channels. To operate in the narrower US UPCS band, Model CA22CD uses five carrier frequencies, with a total of 60 duplex channels.

Electrical and RF Features
- Modular eight‐position jack for connection to analog host equipment (Model CA12CD‐S’s jack is six‐position; we’ve added two contacts to accommodate the optional second receive channel.)
- New USB port for use with PC‐based voice systems and training simulators
- Carbon‐, electret‐, and dynamic‐mic emulation (analog‐host connections only)
- Over‐the‐air (OTA) subscription of remote to base. (The remote does not need to be docked in the base.)

1 The talk‐volume fine‐adjust buttons, the talk‐volume coarse‐adjust switch, and the receive‐volume coarse‐adjust switch are only active when the base is plugged into an analog host. These controls are not active in the USB interface. When connected to a USB host, talk and receive volume can be controlled in the host PC, and receive volume can be fine‐tuned with the receive‐volume fine‐adjust rocker on the remote.
