PU 910

Digital Controlled 16 Channel System

The PU 910 sets new standards in the area of wireless transmission technology. The latest 4 layer PCB

structure in SMD technology with components only 0.07 x 0.15 mm in size, this technology, also used in

mobile phones of the latest generation, makes an excellent audio performance possible with the highest

operating reliability and long battery life, due to low current consumption. The newly developed digital

squelch control offers extremely high operating reliability. The simultaneous transmission of the battery

status of the transmitter to the receiver provides convenience and security at the same time. If the battery

capacity is only sufficient for 30 - 45 minutes, the “Battery Low” warning is passed on to the receiver,

which can be seen by the sound technician by the use of a red LED. The professional audio design, achieved

through high-grade, low noise pre-amplifiers, in conjunction with the polished PLL UHF technology with 16

bit microprocessors, make the PU 910 the first choice for professional users. The newly developed

compander circuitry uses the latest components for high linearity and minimal interference noise.

Dynamics, audio quality, and operation set new standards at this price/performance ratio.

The receiver in a 9.5" metal casing provides information on all the essential operating parameters, such as

operating frequency, HF and audio level and also the battery status of the transmitter, through its large

illuminated display. The antenna are mounted on the front and can be removed allowing them to be

repositioned or permitting the use of the optional active antenna splitter AS6 in multi-channel

applications. The active antenna splitter AS6 is recommended for the maximum in operating reliability and

high range where more than two PU 910s are operated in parallel. Up to six PU 910 receivers can be

connected to the AS6. For more than six systems, several AS 6s can be cascaded. For the use of the active

AA 900 antenna amplifier, the AS 06 provides a switched phantom feed. The AA 900 antenna amplifier is

recommended to compensate for RF signal loss on long antenna cables. There is a choice of +8dB or +16dB

amplification available. If for example high ranges are required, for open-air environments or in large halls,

the RDA-900 directional antenna set will increase the possible range considerably and optimize operating

reliability. The directional antenna can be installed on microphone and loudspeaker stands or, for instance,

in a truss system. In addition to the connection cables, the delivery specification for the RDA 900 set also

includes a rain cover for outdoor applications.
