Four‑channel wireless power for busy stages
The Galaxy Audio CSL4 packs four independent Digital UHF True‑Diversity receivers into a single 1U rackmount chassis. It shares the same high‑performance RF features as the single‑channel CSL with Auto Scanning, RF Spectrum Analyzer, and IR Sync—so you can easily manage multiple transmitters in congested RF environments. With four channels, it’s ideal for multi‑performer setups, theatre, worship teams, and installed sound.
Key Features
- Quad‑channel digital True‑Diversity receiver with four independent receivers in one 1U rack (19 in) chassis.
- Auto Frequency Scanning & RF Spectrum Analyzer simplifies multi‑channel frequency coordination.
- IR Sync pairs each transmitter with its receiver instantly.
- Up to 1480 selectable frequencies across multiple bands:
- P‑Band (470–507 MHz) – 1,480 frequencies; up to 18 compatible systems.
