(v1.1 29-06-2021)
Thank you for purchasing the DuTCH audio MC1.3 monitor controller. In this manual we will
explain how this device works and how to use it.
Important Safety Instructions:
Please follow these precautions when using this product:
Read and keep these instructions.
Heed all warnings and follow all instructions.
Dangerous voltage lives inside this machine. Opening is only allowed by qualified service
personnel.
Unplug this machine during lightning storms or when unused for long periods of time.
Do not use this machine near water or outside.
Clean only with a dry, soft cloth. Do not spray any liquid cleaner onto the cabinet, as this
may lead to dangerous shocks.
Do not install near any heat sources such as radiators, heat registers, stoves, or other
machines (including amplifiers) that produce heat. Avoid exposure to direct sunlight.
This machine typically runs slightly warm when operated. Install in a normal ventilated
area. If the product will be used in a rack, make certain there is sufficient air movement

or moisture.
Basics:
The MC1.3 is a 1u 19 inch monitor-controller with durability and easy control in mind.
The MC1.3 is based around a passive 64 steps, 1dB per step, parallel relay-based attenuator.
Compared to a standard serial attenuator or even worse, a potmeter, a parallel attenuator
keeps the same impedance throughout it’s complete range. This means that it’s way more
transparent because of a constant load. Another plus is that because it has way less resistors
in-line, it also reduces the Johnson noise to an absolute minimum.
The MC1.3 has 4 balanced inputs, 3 balanced outputs (2x stereo, 1x mono), a balanced
directout (for example as a metering output), a class-A headphone amp and high quality dual
