PRS-4P125 Power Amplifier 4x125W
There are four types of Power Amplifier units in the Praesideo product range. These differ in the number of amplifier channels per frame: one two four or eight. The overall power rating is 500 watts for all of the amplifiers.
The Power Amplifiers can be set to 100 V 70 V and 50 V output tappings. They have short-to-ground and short-circuit detection functions and can generate their own pilot tone for supervision purposes.
Region specific versions of these amplifiers are indicated by a suffix to the typenumber (-EU - CN ...). The amplifiers are completely identical but may differ in certifications power cord and country of origin.
The Power Amplifiers receive input signals over the network. They also have two auxiliary audio inputs (four for LBB 4428/00) for local audio. Their eight control inputs are freely programmable for system actions and priorities can be assigned to these inputs.
Each control input has the ability to monitor the attached line for open and short-circuits. Control outputs are freely programmable for faults and call related actions.
The 2 x 16‑character display and the rotary control enable local status enquiries. The display shows the VU‑meter reading when the audio monitoring mode is active. Audio can be monitored by headphone. The units are self-monitoring and continually report
their status to the network controller. They support both single branch and redundant loop cabling. The amplifiers have a changeover facility for spare power amplifier switching. Changeover relays are included with the units. The amplifiers have a 48 V DC back-up
The digital audio processing can handle three parametric equalization sections and two shelving equalization sections per channel with configurable audio delay.
