Palmer PAOCBXLRFXLR Female Audio Over Cat Box

Introduction
The Palmer PAOCBXLRFXLR Female Audio Over Cat Box ensures clean, balanced audio signals, even over long cable runs. The wupper Line Isolation Box is equipped with 6.3 mm jack sockets on the input and output sides, which can be operated both balanced and unbalanced. There is galvanic isolation between input and output by means of a high-quality transformer, and hum loops are reliably eliminated. The Line Isolation Box is perfect for balancing audio signals, and audio signals can also be transmitted over long cable runs without hum. For detailed setup instructions, you can also refer to the Palmer Wupper Line Isolation Box Instruction Manual.

FAQs
Q: What kind of audio signals does it support?
Depending on the wiring, it can handle both mono and stereo balanced audio signals, usually from XLR microphones or line-level sources.
Q: Can it be used for both microphones and line-level instruments?
Indeed. It can handle both higher-level line signals and low-level microphone signals, although it always checks the input level to avoid distortion.
Q: Does it require power?
No, the PAOCBXLRFXLR is a passive device that uses the audio signal to communicate over CAT cable without the need for external power.
Q: Is it compatible with any CAT cable?
It is compatible with CAT5, CAT5e, CAT6, and CAT7 cables.
Q: Can I use it for stage setups or live sound?
Indeed. Long cable runs without signal deterioration make it perfect for live sound, stage setups, and studio settings.
Q: What is the frequency response of the device?
For professional audio applications, the box’s full-range audio architecture ensures transparent signal transmission, usually between 20 Hz and 20 kHz.
Q: Can it handle phantom power for microphones?
No. It does not transmit phantom power because it is passive.
