ADDAC710 - Balanced Outputs
The ADDAC710 is a dual-channel isolated DI box designed to keep the sound coming from a modular system free from any undesired noisy interferences, ensuring that the output reflects what the modular is actually producing. It provides galvanic electrical isolation between the modular system and external sources, preventing impedance mismatch and ground loop induced hum.
The ADDAC710 circuit is designed around a unity 1:1 type audio transformer operating in the 20Hz to 20kHz range. This impedance matching transformer provides two fully balanced outputs via XLR connectors.
The ADDAC710 is an alternative to the ADDAC800X High-End Outputs module, featuring a redesigned circuit using a smaller transformer that also reduced its depth, allowing it to fit shallow Eurorack cases.
The LIFT/FLOAT/GND 3-way switch allows choosing between lift, ground, or floating ground:
- In the LIFT position (left), the module circuit will be "lifted" to ground through a 100R resistor and a 10nF capacitor.
- In the FLOAT position (middle), ground will not be shared, leaving input and output grounds completely separate from each other, fully isolating both signals.
- In the GND position (right), ground will be shared between inputs and outputs; here no isolation is used.
Any of these three positions may be the best option for avoiding ground loops or any other undesired interference occurring between a modular system and the sound system it's connected to. Try out which option works best in any given situation.
