In the scramble to produce ever-more weird and wonderful Eurorack modules to mash and mangle your bleeps and squeaks, sometimes the basics can get overlooked. And one thing that's very basic is how on earth do you listen to the sound that's output by your setup? Hardware specialists 4ms have come out with three new modules that provide different ways to monitor your Eurorack system - Listen 4, Listen 4Q and Listen IO.
The Listen Four is a four channel stereo mixer with line, modular, and headphone outputs. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.
The Listen Four Quarters is a four channel stereo mixer with 1/4" (6.35mm) TRS balanced outputs and 1/8" (3.5mm) headphones output. Two mono channels with Pan knobs and two stereo channels with dual inputs provide optimal compatibility with both stereo and mono signals. The Listen Four Quarters can be daisy-chained to other Listen modules to create a larger mixer with sub-mix outputs.
The Listen IO is a simple module which gets signals in and out of a Eurorack system by converting to and from normal modular levels. The top section converts any external signal to modular levels by providing up to 30x gain (+30dB), allowing you to use table-top synthesizers, keyboards, phones/tablets, computers, toys, microphones, etc. in your patches. The bottom section does the opposite: modular signals are converted to normal line level signals. The bottom two jacks can be used as line outs or as headphone jacks, so you and a friend can listen in stereo at the same time. Each section has two inputs and outputs for use with a stereo signal or two mono signals. An LED bar graph for each output shows the signal level and clipping.
