Page 4: Introduction
Our Engineering Simplicity philosophy is evident in the functionality and user-friendliness for each model. The three models in the series, PLS-X1, PLS-X3 and PLS-X5 are identical with the exception of output power. Each model offers three inputs, two programmable, including a 100V line setting, a self-test mode, loop- and speaker amplifier monitor. -

Page 6: Input Level Control
Explanation Note Univox PLS-X series is operational only if a loop cable is connected to the driver. Otherwise, the Peak indicator is lit constantly as a warning. All controls are regulated with a small screwdriver. 1. Input level control (In1-In3) Each input can be set to correct input by appropriate single-turn potentiometer located on the front panel. -
Page 7: System Diagnostics
5. System diagnostics Univox PLS-X series has a built-in system test. We recommend that this feature is used periodically, at least monthly, to check the integrity of the loop driver, its inputs and the loop condition. To access the system diagnostics mode, set the switch on the front panel to the right. -
Page 8: Voltage Clipping/Peak Led
Note In some cases metal reinforcement can actually reduce the voltage requirement. 9. Loop monitor/headphones socket Univox PLS-X series has a powerful speaker amplifier and a 3.5mm headphone socket ® built-in. The headphone socket is on the front panel, the speaker connectors (13) and volume control (17) are placed in the rear panel. -
Page 9: Loop Terminals
The voltage rating of the supply is dependent on the model. Only Univox approved power supplies correctly rated for the loop driver model should be used. The use of incorrectly rated, or third party power supplies will invalidate your 5 year warranty. -
Page 10: Remote Output Monitor Connector (Screw 5+6)
16. Remote output monitor connector (screw 5+6) A LED connected to this terminal will mirror the operation of the 0dB output current Level LED on the front panel, thus allowing the monitoring of the presence of output current in a more convenient location. -
Page 11: Input 3
20. Input 3 Input 3 Input 3 is an unbalanced line input. The sensitivity is adjusted using the control on the front panel. The source may be connected using the RCA connector (L/R) or the Phoenix screw terminal, but can't be used simultaneously. If the RCA input is used: Mono signals are connected through R or L and the earth connection. -
Page 12: Override On/Off Dip Switch 4
Note The DIP switches should be set in the appropriate position before connecting the input signal to avoid causing damage to the input. 24. Override On/Off (DIP switch 4) Input 2 With the DIP switch in ‘down’ position, Input 2 is set as the Priority Input. In this case, when a signal is detected, all other inputs will be suppressed. -
Page 13: Line/Mic Dip Switch 2 + 3
27. Line/Mic (DIP switch 2+3) The switch is used to alter the sensitivity of the XLR input for line and microphone. With the 2 DIP switches in the ‘down’ position, Input 1 is set to Line sensitivity. With the 2 DIP switches in the ‘up’ position, Input 1 is set to Mic sensitivity. For sensitivity levels, see Technical Specification on page 22-23. -
Page 14: Prepare Installation
Please refer to www.univox.eu/planning Use Univox Loop Designer (ULD), a free, web-based project planning and design tool that quickly and accurately assists in the design of loop systems. -
Page 15: Placement Of The Driver
Placement of the driver The Univox PLS-X loop drivers will not generate much excessive heat and can be mounted in 19" racks on top of or below other rack components (check that these don’t generate excessive heat), on a wall or another flat surface. In a rack system it is often practical to attach the external power supply to the supporting metallic construction using straps. -
Page 16: Installation
Installation Start-up procedure 1. Disconnect all input and output connections. 2. Each loop must be securely isolated (particularly to safety-ground and other loop connections). Verify the resistance of each loop (approximately 1-3 Ohm). 3. Set all level controls to minimum setting: •... -
Page 17: Output Connection And Adjustments
Note 1 To quickly set up the field strength for a real program source, a PPM instrument is helpful. The Univox Listener has a calibrated level indicator that quickly finds the highest peak. Note 2 When adjusting the field strength peaks, -2dB field strength works best, due to different dynamic headrooms in hearing aids. -
Page 18: Metal Loss Correction Frequency Setting
A guide how to commission a loop system to the IEC performance standard, can be found in the user guide for the Univox FSM 2.0 field strength meter and in the Univox® Certificate of Conformity. These documents are also available on www.univox.eu/certify. -
Page 19: Default Settings
Note To listen to the sound quality, use high quality headphones with the FSM 2.0 or Univox ® Listener loop receiver. The ‘Monitor’ Output socket is a direct reflection of the loop signal current (volume control on rear panel). The sound quality can be easily assessed at this point in the audio chain aiding set up and problem solving. -
