Overview
We collaborated with American bass player (also vocalist, keyboard player, TV composer,
engineer) Melvin Lee Davis to create MLD Bass Preamp & DI. It has tons of functions based
on Melvin Lee's musical experience, and offers the best sound shaping controls such as 3-
band EQ with middle-frequency selection, drive with blend control, speaker cabinet
simulation (Impulse Response file loader) and built-in noise gate with decay and threshold
controls.
Melvin Lee Davis Bass Preamp & DI
MLD Bass Preamp + DI can also be used as an audio interface. You can download and install
the free NUX ASIO Driver, connect the pedal to your computer via USB, use the headphone
output on the pedal for monitoring, then it can send the bass guitar audio signal for recording.
Simply you don't have to use any other output on the pedal or computer.
Audio Streaming and Recording
You can control the pedal with the software and also load/change Impulse Response files.
Visit nuxefx.com and download the software for free.

Or you can set the toggle to POST to use the
preamp and drive functions for DI out
connection. No matter the PRE or the POST
is selected, you can activate/deactivate the
speaker cabinet simulation using the DI
Toggle.
Ground Lift Toggle
If you meet ground loop noise issue, it helps
you to eliminate the hum noise.
1/4" Through Output
Dry signal output, if you want to connect the
pedal to the amplifier in front. You can avoid

产品简介
NBP-5是我们与美国著名贝斯手Melvin Lee Davis 深度合作共同开发的一款贝斯前
级与DI二合一效果器。产品立项初期，我们充分听取了Melvin Lee Davis作为资深
贝斯手的诉求，结合我司多年的效果器开发经验将Melvin所有的想法逐一实现最
终得到了令他感到十分惊艳的成品。本产品搭载了带独立中频调节的三段均衡
设置，带混合调节的过载效果，箱体模拟（可使用第三方脉冲响应IR文件），以
及带阀值设置和“DECAY”设置的噪声门，合理地搭配使用这些功能会让您的贝
斯音色别有韵味。

音频串流与录音
如果我们不提，或许您很难发现这款效果器还可以用作音频接口（录音声
卡）。您只需移步至我们的官方网站下载并安装好配套驱动软件，将本体与您
的电脑通过Micro-B USB线连接，即可体验这款“独特”的声卡。此时，音频讯号
会通过Micro-B USB线串流至电脑，您可以选择将监听耳机连接至本体的3.5mm音
频输出接口来监听实时录音，整个过程您甚至可以不用电脑的监听音箱以及外
接音箱即可高效完成录音工作。
