JBL Compact Passive Volume Controller

The Nano Patch+ from JBL is a versatile passive volume controller in a compact desktop format. It can be used as a physical volume attenuation knob for audio software applications, when connected between a computer audio interface, or soundcard master output and a pair of active (powered) monitor speakers.

Reducing levels from your software only reduces the audio bit depth. The Nano Patch+ allows you to maintain a maximum audio resolution and attenuate your monitoring volume with the confidence that your audio is not compromised. The Nano Patch+ has no active circuitry, buffers, transistors, batteries, or power supply and limits interference to the main passive outputs. It delivers attenuated signal, that is naturally transparent.
