A guide presses power, a receiver locks on within seconds, and the group is moving — no manual channel-matching, no setup delay standing between arrival and the first stop on the route.
Most delays before a guided tour starts have nothing to do with the route — they come from getting a stack of receivers matched to the right channel. The B7-1 solves that step directly: a long press on the receiver's pairing button starts the connection, the LCD confirms "Pairing in progress," and a steady green light signals it's locked to the transmitter. What used to take a briefing now takes a few seconds per unit.
Built on a 2.4GHz digital link with a working range of 50 to 300 meters, the system holds a stable connection whether the group is moving through a single hall or spread across an outdoor site.
A single long press connects a receiver to its channel, with on-screen confirmation and a solid green indicator once the link is set — no code entry, no menu navigation.
The transmitter's single-directional microphone runs an NC mode that suppresses ambient sound, so the paired connection stays clear even in busy or noisy settings.
A three-position switch — On, Key Lock, Off — keeps a paired session from being disrupted by accidental button presses once the tour is underway.
20 hours from the transmitter and 30 hours from the receiver mean a paired set stays connected through a full day without a mid-tour recharge.

Fast pairing gets a group of visitors listening within moments of arrival, without the wait that usually opens a tour.
Delegations moving between buildings can be re-paired quickly if a receiver drops or a new visitor joins mid-visit.
Large rooms full of attendees can connect receivers in sequence without pulling a technician in to manage the process.
Noise cancellation and a locked-key transmitter keep the group connected past running equipment and workshop noise.
A 300-meter open-space range covers groups spread across outdoor routes without losing the signal between stops.
Booth staff can pair a fresh receiver to a visiting buyer in seconds rather than pausing a walkthrough to set up equipment.
Bulk orders on the B7-1 can go beyond a standard configuration. Casing, channel setup, and documentation can all be adjusted before production starts, so the units that arrive already match how your team plans to deploy them.
A long press on the pairing button typically connects a receiver within a few seconds, confirmed by the on-screen status and a solid green light.
Receivers retain their paired channel, so a power cycle during a tour doesn't require re-pairing unless the channel itself is changed.
Yes. NC mode is a toggle, so it can be switched off in quieter settings where it isn't needed.
Casing color, logo printing, and packaging can be adjusted for bulk orders. Contact sales with your target volume for a customization quote.
