The PM 1122 is a high-quality preamplifier that offers a four-level priority system with emergency input, offering a wide variety of possibilities that make it an extremely versatile unit, suitable for any situation imaginable. It features an adjustable-volume acoustic alert, and all controls are equipped with LED indicators offering a clear view of the equipment's status. It features 5 microphone / line inputs, each with phantom power. There is a general noise gate for the microphone inputs. Each signal is assignable, via a DIP selector located on the front panel of the unit, to one or both output zones. Each input features individual tone, gain, and volume controls. The 5th mic / line input can connect to / from another PM 1122 unit. The outputs feature a two-zone section. Both feature a selector that allows switching between 4 line inputs, as well as independent controls over music and microphone levels, and bass and treble controls. The PM1122 offers various remote control options: The PM 1122R is a wall-mounted analog control that features music level control and microphone mix level control, as well as a line input selector. The PM 1122RL is a wall-mounted analog control with a local input. It offers the same functions as the PM1122R, but also features an XLR microphone input and a balanced line input (mini jack) with volume and tone controls. Both wired analog controls can be connected to the preamplifier via a UTP CAT5 cable. In addition, the preamplifier can also be controlled through a PC computer application. The optional PM1122INT remote interface connects to the preamplifier via a standard UTP CAT 5 cable for each output zone, and to the PC computer via an RS232 connection. The software is included. Wireless remote connection is also possible. A PM1122W wall-mounted wireless controller can be installed wherever the user desires. This interface, which offers source selection, and microphone and music volume controls, connects to the PM1122INT interface via the PM1122R, an antenna that can be connected to this interface. THE PM1122W is a wireless remote control for the PM1122 with a thickness of only 15mm that runs on lithium batteries without the need for cables. With it, it is possible to control the source selection, the microphone volume, and the zone music volume. Its range is 30 meters in indoor spaces and 100 meters in open spaces, and it does not cause interference with other remote controls since it operates on the 868.3 MHz frequency. It is possible to use up to 32 PM1122W transmitters with one PM1122 receiver. Available in black, white, and silver.
