Introduction
Multifunctional L3 audio switcher is originally designed by Douk Audio Studio, it is not only an audio switcher that can work in 1-IN-3-OUT and 3-IN-1-OUT mode to make contrast among different audio source, amplifier or active speakers etc.; but also a loop switcher that can add up to 3 audio effectors to create multi-layered musical effects and enhance the richness and dynamism of music to bring more creative space and fun.
Features
- 3 channel audio loop switcher with bypass: L3 can add up to 3 preamps/equalizers/effectors to create multi-layered musical effects and enhance the richness and dynamism of music whether in daily listening or studio recording, brings more fun and creative space. Also support one button bypass to enjoy the orginal sound and compare the overlay effects of different loops.
- 3-way stereo audio switcher: 2 working modes, suitable for debugging equipment and do contrasts among different devices (3-IN-1-OUT for comparing audio source, preamp, equalizer etc.; 1-IN-3-OUT for amplifiers and active speakers.), specially designed for audiophiles who have several audio sources and outputs.
- Customized VU meter and remote control: with dual large and full-color VU meters (45mm), the backlight color and brightness can be adjusted freely; driven by a dedicated VU driver chip to show the level of audio signal dynamically and accurately in real-time; remote control design, convenient to adjust all settings from the distance.
- Advancd circuits and high-quality sound: with built-in power isolation circuit, no common ground noise will be generated even sharing the same power with audio players; adopts100K high-impedance input circuit, when inputting linear audio, L3 has little impact on the sound source to ensure its the purity.
- Attractive looking and powerful design: all metal case and CNC machined panel with good shielding performance to avoid interference; stepless adjustment knob, all I/O interfaces are gold-plated to ensure the smooth transmission of the original audio signal to minimizes the loss of the signal. Powered by DC 5V, easy to carry and convenient to use at anytime and anywhere.
Warm tips:
1. The series connection button is only available in loop mode. In this mode, the audio signal from IN interface can be arbitrarily passed through one channel (Chanel 1/2/3) or two channels (Channel 1+2/1+3/2+3) or three channels (Channel 1+2+3 ) and then to OUT interface.
2. Not support guitar recording or singing directly, you need to add a preamp to convert the guitar and mic signal to LINE OUT before connecting to L3.
3. In 3-IN-1-OUT or 1-IN-3-OUT mode, only one channel can input and output at one time, the 3 channels of IN or OUT cannot work at the same time.
4. In bypass mode, the audio signal will pass through from IN to OUT directly, not pass through channel 1/2/3.
5. For safer and faster delivery, without DC 5V power adapter and no batteries (2*AAA) inside the remote control, please prepare by yourself.
6. Compatible with most audio devices, but cannot guarantee 100%. If there exists common ground noise, please add an isolation module (LINK) between L3 and your device.
