Product Description:
- Douk Audio HiFi Pure Vacuum Tube Microphone Preamplifier
- This is Douk Audio Studio with Little Bear newest pure tube balanced microphone preamplifier in 2017. Compared with hybrid preamplifiers which use transistors to amplify sound, M1 will amplify all signals via vacuum tubes(6N2). Furthermore, it also uses a rectifier tube(6Z4) in the power part. In this way, the specific characteristics of vacuum tubes can be showed in the sound output, which make the sound more clear, warm and charming.
- M1 supports balanced/unbalanced input/output. With the bulit-in phantom power, it can provide much convenience and little background noise while using your microphones especially with balanced input. Since noise can't be reducted with unbalanced input, it is normal that there is more noise. While using a microphone with metal case, please use a microphone support instead of touching it directly to avoid noise.
- M1 has a warm sound output and a powerful amplifying effect. It will be very suitable for recording, karaoke and webcast. Its special "one button to mute" function will add much convenience while chatting online. What's more, M1 also supports two kinds of vacuum tubes: 6N2 and ECC83, which will be a good news for some professional audiophiles.
