Frequently Asked Questions
What microphone capsule does the XSW 2-835-A use, and how does it affect vocal sound?
The system uses Sennheiser's evolution e835 dynamic cardioid capsule — the same capsule found in the wired e835. It has a slightly forward presence peak that adds definition and cut-through on vocals in loud stage environments, with a smooth low-mid body that avoids the thin, brittle sound of budget wireless capsules.
How does the true diversity receiver improve performance in a live venue compared to single-antenna systems?
True diversity continuously compares signals from two independent antenna paths and selects the stronger one in real time, so the audio signal stays clean even when the transmitter rotates or moves behind obstructions. On a busy live stage, this effectively eliminates the dropouts and static bursts that non-diversity systems suffer when a performer turns away from the house.
How many simultaneous wireless systems can operate in the same frequency range?
The XSW 2 series supports up to 12 simultaneous channels within its UHF frequency band. The automatic frequency management system scans the RF environment and assigns clean frequencies, which simplifies multi-system setups significantly compared to manual coordination.
Does the receiver's metal housing affect its rackmount practicality?
The metal housing is a build quality asset — it resists the dents and flex that plastic chassis suffer in touring racks. A rackmount kit is included in the box, so the receiver can be mounted in a standard 19" rack without additional hardware purchases.
What batteries does the handheld transmitter require, and what is the expected runtime?
The handheld transmitter runs on two AA-size batteries at 1.5V. AA alkaline or NiMH rechargeable batteries work. Runtime varies by output power setting, but the AA format means batteries are universally available at any venue if you run short mid-show.
