Boutique VA-EOL End of Line module for Attenuators or branch speaker lines.

To monitor the long speaker lines, the VA-DLC-100/VA-DLC-70 dummy load capacitor module 100V/70V SP-line can be added on the PA/VA systemto detect the open and short circuit of entire speaker line even the last speaker. However, for advanced configuration such as installs the VAT volume attenuators in the 3 wire speaker line for volume control, the impedance of speaker line is changed after the volume attenuators adjustment. Furthermore,for branching the speaker line wiring, a cut of partial branching may not change the overall impedance that obviously. Therefore, the VA-EOL is the only solution which can adapt the changing impedance and detect open or short circuit for each branch. By installing the VA-EOL at the end of speaker lines, the system can indicate which speaker line is open or short circuit, helping to save the analysis time. In addition, the installation does not require additional loopback cabling and is powered by BTQ-VM/SG/SL via speaker line without affecting the audio signal.
