Short description:

Simultaneous, two-way, wireless intercom system. Ideal for event production scenarios


Simultaneous, two-way, wireless intercom system works well in an event-production scenario – allowing producers/directors to communicate immediately and accurately in full-duplex mode with crew members in different house locations.  The director and assistant director can speak simultaneously, while crew members can hear both the director and assistant director. Crew members can participate as listen-only or can access two-way mode with the quick push of a button. The director has priority and controls the discussion. This system in the 2.4 GHz band offers a patented, frequency-hopping technology for low-noise, crystal-clear audio and less interference from other products.  The dual-muff headset microphones are ideal for use in high-noise environments.



  • Set-up lock (SLOC) enables administrator to lock each DLT 300 to prevent unauthorized changes to a Digi-Wave system set-up.
  • Four digit secure key, entered into each group members’ DLT 300, prevents unauthorized individuals from listening in on the group.
  • Four independent groups can be operating simultaneously within a range of up to 200 feet outdoors/300 feet indoors (in 1- or 2-way mode, depending on environmental conditions). Outside of this range, other groups can be in operation.
  • Push to talk button can mute unwanted background noise 
  • All day operation (up to 14 hours on one charge) 
  • Easily import/export additional audio via 3.5 mm mini plug
  • 2-year-warranty
  • The transceiver shall be a digital transceiver operating on the 2.4 GHz ISM band utilizing FSK modulation with patented frequency-hopping software to reduce interference potential. It shall be compatible with the DLR 360 Receiver. It shall be housed in plastic enclosure 4.07" H x 2.43" W x 0.44" D  (103.3 x 61.8 x 11.3 mm), have an internal rechargeable Lithium Polymer battery with smart charge built into the transceiver and an LCD on the front panel displaying, battery level, mode, time, channel number, group number, and number of other DLT’s with the talk button on (up to 6). It shall have a built-in microphone and speaker for users opting not to use a headset.
  • The transceiver shall have a battery life up to 14 hrs per charge and take approximately 5 hrs to reach full charge. Power will automatically shut off after approximately five minutes when no RF signal is detected from any compatible devices.
  • The transceiver shall operate in one-way or two-way mode (up to six speakers in a group at any given time) and have a range of up to 750 ft (229 m).
  • The transceiver shall have power, vol +, vol -, talk, CH +, CH -, v, GRP and ^ buttons. It shall have an illuminated talk button with a tactile braille dot.
  • The transceiver shall have a menu setup mode via front panel buttons configurable for (1 or 2-way operation), (master or guest operation) and (floor + 14 language portable interpretation where common floor language is used).
  • The transceiver shall have 3.5mm mono/stereo microphone and headphone jacks, all controls are on the front of the unit and a multi-pin style jack on the bottom provides battery charging access.
  • The transceiver shall operate 15 simultaneous channels in interpretation mode, support 4 simultaneous groups in two-way mode, allow a maximum of 4 simultaneous talkers in 2-way mode, and a maximum of 6 simultaneous talkers in Intercom Mode. It shall have a repeater mode to increase the range of the system.
  • The transceiver shall have a 74 dB (A weighted) SNR with a frequency response of 140 Hz to 11.5 kHz in Conference and Interpreter Modes and 140 Hz - 7.6 kHz in Intercom Mode.
  • The transceiver shall have FCC, Industry Canada, CE approvals and be RoHS, WEEE and RCM compliant. 
  • The transceiver shall have a two year parts and labor warranty (90 days on headphones, battery, charger and earphones). 
  • This transceiver shall be the Williams Sound model DLT 300.
