Envoi HL Transmitter

Envoi Belt Pack Transmitter with Lavalier and Headset Mic

Key Features:

  • Compact belt pack transmitter includes both headset and lavalier mics
  • Up to 8 hours on one set of AA batteries
  • Easily paired with either the Denon Professional Envoi or Marantz Professional Voice Rover
  • Use with the existing receiver in the Envoi loudspeaker or add a second receiver (sold separately)


The Envoi HL Transmitter is an accessory for the Denon Professional Envoi powered loudspeaker. It includes a battery powered belt pack transmitter together with both a headset mic and lavalier mic. The Envoi HL Transmitter may be used with the existing receiver in the Envoi or a second receiver may be added (sold separately as Envoi Receiver 2).

The Envoi HL Transmitter is a perfect solution where the included Envoi handheld mic is not practical or appropriate; for instance, the headset mic is excellent for fitness applications while the lavalier mic may be an alternative for instructional settings.

The belt pack is compact and will operate for up to 8 hours on a single set of AA batteries. It features a very low-profile antenna and input attenuation switch, as well as an LED status light visible from the top or front to confirm operation.

The Envoi HL Transmitter may also be used with the Marantz Professional Voice Rover.
