The Active Speaker Starter Set with Nano Patch+ from SM Pro Audio will help you optimize your current monitoring rig. It includes isolating foam monitor pads, connection cables and the Nano Patch+ level controller.
The foam pads sit beneath your active monitors and prevent sonic distortion due to vibration. The included cables connect your audio interface with the Nano Patch+ and then to your speakers.
The Nano Patch+ allows you to attenuate your audio signal without impacting the quality. Simply place it in your signal path between your computer or audio interface's master outputs and your stereo speakers. The Nano Patch+ will provide completely passive volume control - with no active circuitry, buffers, transistors, batteries, or power supply that can impact your audio signal. It has a pair of XLR/TRS combo inputs and 1/4" TRS outputs. There is even a 3.5mm stereo mini input and output connector for use with smaller audio sources and portable speakers.
