LA-2L Upgraded Audio Signal Isolator Professional Current Noise Cancellation Support Attenuation Switch

LA-2L Upgraded Audio Signal Isolator Professional Current Noise Cancellation Support Attenuation Switch

Compared to classic LA-2, LA-2L upgraded:
- Add a three level attenuation switch for input.
- Three grounding mode selection switches.
- Audio transformer upgrade, circuit upgrade.
- Add 'M' mode and output grounding mode.
- Add silicone protective kit for better protection against collisions.
- Industrial grade design of the shell, CNC machining.

Description:
- The upgraded LA-2L audio isolator adopts a custom-made permalloy material audio transformer from an imported manufacturer as the signal coupling and conversion between input and output. The imported connector for NEURIK and double-layer shielded gold-plated circuit design enable signal isolation and conversion between input and output. The input adopts a mixed interface of 6.35 and XLR, and the output adopts an independent interface of 6.35 and XLR, which can be converted between balanced and unbalanced. There are suspension and grounding switches, as well as input signal attenuation switches for Group A and Group B. The input high-level signal can be attenuated, converted, and isolated to completely isolate the potential difference between the two systems, avoiding AC sound interference caused by grounding issues and preventing damage to the input components of the equipment due to excessive potential difference. Realize secure transmission of audio signals.
- Remove the electric current sound generated by connecting laptops, cameras, broadcasting consoles, simultaneous interpretation equipment, electronic musical instruments, other devices to the mixing console and noise generated by impedance mismatch between devices. It is also suitable for theaters, large outdoor performances, lightning protection, sound engineering, multimedia conferences, entertainment venues, exhibitions, etc. It is an essential equipment for cascading audio systems.

Features:
- Two channels are physically isolated and converted between balanced and unbalanced.
- Each channel is equipped with three attenuation switches and three grounding mode selection switches.
- Isolate external interference, isolate current sounds and noise generated by non common ground.
- Protect equipment from damage caused by ground voltage differences (ignition, static electricity) and improve sound quality.
