PM2ROverview
The PM2Relay (PM2R) is a 16 channel multiplexer for delivering powered and
unpowered signals to a device. When coupled to a power amplifier such as the SA1,
the PM2R can transfer several watts of power to standard four ohm and eight ohm
speakers.
The PM2R is designed to be used as a “de-multiplexer”, that is, one input
switched to 16 possible outputs. However, it can also be used as a straight
multiplexer (16 inputs to one output). This is accomplished by sending signals in to
the 16 “signal out” channels. The selected channel will be output on the “signal in”
channel. Users that are doing this should be very careful, as it is easy to exceed
the maximum input values when sending in 16 input signals. The aggregate input
of all signals should never exceed two amps, or 15 Volts, because severe
damage can be caused to the module.
Each RP2 can control up to four PM2R devices and each PM2R can have one
active channel. Therefore, a maximum of four signals can be played out
simultaneously when using four PM2Rs.
To connect to a System 3 module, attach the 25-pin, blue ribbon cable from the
RP2 device to the PM2R. Connect your powered signal source to the Signal In and
connect the signal out to the RP2 connection on the PP16, or your own connectors.
The channel outs on the PP16, from the left to right, correspond to the 16 channels
(0-15) on the device.
Power
The device is powered via the System 3 zBus (ZB1PS). No PC interface is
required.
PM2RFeatures
The PM2R uses a bit pattern code to control the output of a powered signal to one
of sixteen output channels. The powered signal can come from any power amplifier
such as the SA1 (Stereo Amplifier) or the HB7 (Headphone Buffer). The PM2R is
