    CHAPTER 2: Installation The PSR1212 is designed for easy installation and setup. All connections are made through rear-panel connectors. This chapter provides instructions on making hardware connections, creating an expansion bus network, assigning device ID numbers, selecting the mixer mode, and using the front panel LCD menus.

  • Page 16: To Connect The Unit

    Plug in the PSR1212 to complete the installation. The power output [A] will operate at any level between 100–240VAC and 50–60Hz. If you are installing only one PSR1212 and are not connecting it to any other XAP or PSR1212 units, you have completed the hardware installation.

    RJ-45 jumper. If your units are further apart, use category five twisted-pair cable. The maximum distance between interconnected PSR1212 or XAP 800/400 units is 80 feet (24 meters). Expansion bus cable length is calculated between PSR1212s and XAP 800s/400s.

  • Page 18: Device Ids

    Once your expansion bus connections are made (and if you have more than one PSR1212 at a site), you need to set up a unique expansion bus device ID number— a network address— for each PSR1212 on the network. As shipped from the factory, all PSR1212s are set to device ID 0.

    Adaptive Ambient This portion of the mixer monitors the varying ambient noise level in the room and changes the threshold level at which a microphone gates on. Ambient Level The manually-set background noise level upon which the PSR1212 bases gating protocols. Used only if the Adaptive Ambient feature isn’t used.
  • Page 134 Constant Directivity Horn Equalizer (CD Horn EQ) Horn drivers commonly used in arrays in arenas and auditoriums have an inherent 6dB/octave high frequency rolloff. The PSR1212’s CD Horn EQ compensates for this characteristic. Crossover A device that passes designated frequency segments of an audio signal to various loudspeaker elements in a sound system.
  • Page 135 E-bus network. Because up to eight PSR1212s can be used in the same network, the device ID range is 0–7. Device Type A number which identifies the type of unit. For example, a PSR1212 is device type 5.
  • Page 136 Gain The amount a signal is increased over a given reference, typically 0. Normally specified in dB (decibels). On the PSR1212, gain is adjustable from -65 to 20dB (85dB range) in .5dB increments.
  • Page 137 Matrix Mixer A mixer that allows routing of any input or combination of inputs to an output or any combination of outputs. In the case of the PSR1212, the matrix mixer permits level control at each cross point in the matrix.
  • Page 138 Off Attenuation The amount of level reduction a microphone is given when the microphone is not gated on. PA Adaptive Mode The PSR1212 recognizes how much loudspeaker audio is picked up by the microphones and then uses this level as the new ambient level when audio is present at the power amplifier.
  • Page 139 Pink Noise An audio test signal containing all the frequencies in a given audio spectrum, with equal energy in each octave. Preset One of 32 configurable memories in the PSR1212. A preset can be programmed with a variety of routing, level, gating, delay, filter, and equalizer settings to meet specific application requirements.
  • Page 140 S–Z buses These eight buses are defaulted as auxiliary mix buses. They are used to route auxiliary audio to and from other units on the network.
