How To Use The Klark Teknik DW 20T and DW 20R Wireless Audio System

They operate on the 2.4GHz frequency band, delivering high-quality stereo audio with ultra-low latency, and provide a transmission range of up to 30 meters (100 ft) in open spaces without obstructions.

Practical Applications

• Transmit audio from mixers, media players, laptops, or musical instruments to speakers without running long cables

• Ideal for restaurants, cafés, meeting rooms, small events, or spaces where clean, cable-free aesthetics are required

Key Features

✅ Stable wireless connection with high-quality stereo audio
✅ Supports both balanced XLR and unbalanced ¼” TS inputs/outputs
✅ Compact, lightweight design for easy installation
✅ Stereo/Mono switch for flexible audio routing

Device Overview & Connections

Each unit features:

• PAIR Button – to link the transmitter ( DW 20T) with the receiver ( DW 20R)

• LEVEL Knob – adjusts input level (on DW 20T) or output level (on DW 20R)

• SIGNAL LED – indicates audio signal status (Green = normal, Red = clipping)

• XLR & ¼” TS connectors – compatible with most professional audio gear

• Stereo/Mono switch – choose between stereo playback or summed mono

• DC IN power port – connects to the included power adapter

Quick Setup Guide

To establish a wireless link between the DW 20T (Transmitter) and DW 20R (Receiver):

✅ Step 1: Connect DW 20T to the Audio Source

1. Identify your audio source (e.g., mixer, media player, laptop, musical instrument).

2. Choose the appropriate connection:

   • Use XLR for balanced, noise-free signals

   • Use ¼” TS if XLR is unavailable

3. Plug the cable into the INPUT port of the DW 20T.

4. Ensure the connection is secure to avoid dropouts.

✅ Step 2: Connect DW 20R to the Audio Destination

1. Identify your audio destination (e.g., active speakers, another mixer, or a power amplifier).

2. Choose the appropriate connection:

   • Prefer XLR for balanced output

   • Use ¼” TS if needed

3. Plug the cable into the OUTPUT port of the DW 20R.

4. Double-check all connections.

✅ Step 3: Power On and Check LEDs

1. Connect the DC power adapters to both units.

2. Plug the adapters into a reliable AC outlet.

3. Confirm the POWER LED is lit on both devices.

✅ Optimal Placement & Range

• Keep the distance between DW 20T and DW 20R under 30 meters for best performance.

• Avoid large obstructions like concrete walls or metal structures.

• Keep away from potential interference sources like Wi-Fi routers, mobile phones, or strong Bluetooth transmitters.

• Place both units higher off the ground with a clear line of sight when possible.

Pairing (Linking) DW 20T & DW 20R

• 1:1 Pairing (One transmitter to one receiver)

  • Hold the PAIR button on DW 20T for ~4 seconds (LED will flash rapidly).

  • Within 30 seconds, hold PAIR on DW 20R for 4 seconds.

  • When LEDs on both devices turn solid, pairing is successful.

• 1:N Pairing (One transmitter to multiple receivers)

  • Repeat the same pairing process for each additional DW 20R.

  • One DW 20T can broadcast to multiple receivers simultaneously.

• Reset Pairing

  • Hold the PAIR button on DW 20T for 10 seconds to clear all previous receiver links.

Adjusting Levels & Signal

• Use the LEVEL knob to adjust input/output gain.

• Monitor the SIGNAL LED:

  • Green = normal signal

  • Red = clipping → reduce LEVEL to avoid distortion

• Stereo Mode: for two-channel music playback

• Mono Mode: when sending the same signal to multiple speaker zones

Common Issues & Troubleshooting

• No connection?
  → Check pairing status, ensure both units are within range, and reset pairing if needed.

• Audio dropouts or interference?
  → Reposition devices away from Wi-Fi routers or metal obstructions.

• Clipping LED (red)?
  → Lower the LEVEL knob to prevent signal overload.

Maintenance Tips:

• Clean with a dry cloth, avoid moisture and extreme heat.

Real-World Applications

• Restaurants & Cafés: Stream background music wirelessly without running long cables

• Meeting rooms & conferences: Connect laptops or mixers to installed speakers seamlessly

• Small events: Send audio from the stage to speakers in different areas

• Multi-zone audio: One DW 20T can feed multiple DW 20R units across different rooms
