ADDAC System ADDAC711 BALANCED INPUTS 2022 - Black

ADDAC711 is a dual channel Isolated DI box and is all about keeping the sound coming into your Modular free from any undesired noisy interferences, making sure that what you’re getting from your inputs is what your external hardware is actually producing. It provides galvanic electrical isolation between the Modular system and external sources preventing impedance mismatch and ground loop induced hum.

ADDAC’s 711 circuit is designed around a unity 1:1 type Audio Transformer operating in the 20 Hz to 20 KHz range, this impedance matching transformer provides two fully balanced outputs (via XLR connectors).

The LIFT/FLOAT/GND 3-way switch lets you choose 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 ins and outs grounds completely apart 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 form of avoiding ground loops or any other undesired interference occurring between your modular and the external hardware. Try out which one of these options will work best in any given situation.

LEAD TIME - IMPORTANT NOTE:
Although this is also described in our Shop Policy page, it is worth stressing that, by virtue of being a small team and not outsourcing a great part of our production, long story short, we sort of make your order on demand.
After you place an order, it takes 15 business-days to be ready to ship.
This is why you'll see this module as 'in stock', but this in fact means that we do have all its parts and can produce your module. Thanks for understanding, and for choosing us!
