12.TROUBLESHOOTING TIPS 12.1 Audio Problems

1)No power - Is the detachable AC cord fully plugged in? Is the rear panel power switch on?

2)Software doesn’t work on unit - If using ethernet, has the ne24.24M been identified by the software? Are the LEDs on the ethernet jack showing activity? If using RS-232, is the RS-232 cable properly installed to the PC? Is the software communications enabled using a 24.24M object instead of ne24.24M? This is necessary so that the older Protea System Software can be launched from within Protea NE Software for use with RS-232 applications. Is the software device set to 24.24M? Check the security level (section 9.3).

3)No sound - Check to see if the input or output is muted. Is the input Preamp set for the proper gain? Is the input or output Gain turned down? Is the Noise Gate threshold set too high? Is the Input to Output Matrix connected as desired? Does the Matrix Mixer section have any signals turned down or muted? If used as a crossover, make sure the high pass filter (HPF) is set to a lower frequency than the low pass filter (LPF) for a given output. If using a condenser mic, is Phantom Power turned on (input Preamp)?

4)Clip light stays on - Is the input signal level too high? Is the Input Preamp gain set too high? Are input or output gain settings too high? Check to see if an EQ filter has too much boost.

5)Distorted sound but no Clip LED- Check individual EQ filters to see if there is excessive boost.

6)Muffled sound - If expecting full range audio on an output, make sure the crossover settings are not inadvert- ently set so as to limit the pass band.

7)Excessive Noise - Set the Input Preamp gain as high as possible while allowing 20dB of headroom before clipping occurs. Do not use input or output Gain controls for large increases (>20dB) in level from input.

8)Forgot the password - See section 9.3

12.2RS-232 Data Communications Problems

1)Test all data cables. Use RS232 data cables with all conductors wired straight through. Monitor cables and Null Modem cables use non-standard wiring schemes, they will not work.

2)Use a valid PC serial port. You must use a serial port that is not opened to any other application, such as a mouse, modem, or another program. To verify that the port exists look in: Control Panel - System - Device Manager - Ports. While you're there, make sure that the port has no warnings or conflicts.. Finally, you must select the valid port in Protea System Software. This is done under the Communications heading - Com Port Assignment.

WR-2, WR-1, WR-5 specifications

The Ashly WR series, comprising the WR-5, WR-1, and WR-2 models, is a lineup of high-performance wall controllers designed to enhance the user experience in professional audio environments. These devices are particularly useful in applications such as classrooms, conference rooms, and studios, providing intuitive control over various sound systems.

The WR-5 is the flagship model of the series, featuring a compact design that supports multiple zones. One of its standout characteristics is its ability to control various audio source devices, allowing users to select different inputs and adjust volume levels in distinct areas. The WR-5 is equipped with a large, easy-to-read LCD screen, which provides visual feedback on settings and selected configurations. Its Ethernet connectivity allows for seamless integration with compatible systems, making remote management and control straightforward.

The WR-1 is a versatile single-zone controller designed for simplicity. It features a rotary volume knob and a push-button for mute, making it an ideal choice for users who prioritize ease of use. The WR-1 can be integrated into existing setups with minimal effort, and its user-friendly interface ensures that anyone can operate the system without requiring extensive training. The unit supports audio over Ethernet, which allows for flexible placement and installation in various settings.

The WR-2 is designed for dual-zone control, offering similar features to the WR-1, but with the added benefit of managing two distinct audio zones. This model supports individual volume control for each zone, making it perfect for environments where different audio experiences are needed in separate areas. Like its counterparts, the WR-2 employs robust Ethernet connectivity, ensuring that it can communicate effectively with compatible audio systems for a cohesive overall sound experience.

All three models in the Ashly WR series are built with high-quality materials and innovative technology, ensuring durability and reliable performance. They feature intuitive layouts and responsive controls, making them suitable for a broad range of audio applications. Whether it is in a corporate environment or an educational setting, the Ashly WR series provides a sophisticated yet user-friendly solution for managing audio systems effectively.

In conclusion, the WR-5, WR-1, and WR-2 controllers are excellent options for anyone looking to streamline their audio control experience while maintaining high-quality sound management in diverse environments.
