The INs and OUTs of Modular Synthesis: ADDAC System Launches Balanced Input and Output Modules
ADDAC710 AND ADDAC711 Eurorack modules protect your modular system from unwanted noise and interference
Lisbon, Portugal, October 4, 2022 — ADDAC System introduces two new Eurorack modules: the ADDAC710 Balanced Outputs and the ADDAC711 Balanced Inputs. The new modules are designed to keep your modular system free of undesired, noisy audio interference by providing shielding and electrical isolation from external sources. Both modules — which are also available as DIY kits — are just 6HP wide and available now at a price of €160 (710) and €240 (711).
ADDAC710 Balanced Outputs
Designed to only output what your modular system is actually producing minus any noisy interference, the ADDAC710 is a dual channel Isolated DI box that provides galvanic, electrical isolation between the modular system and external sources. Such interference can be very common, and often caused by impedance mismatch or ground loop induced hum.
The ADDAC710 circuit is designed around an impedance matching transformer, operating in the 20 Hz to 20 KHz range, and provides two fully balanced outputs (via XLR connectors). This module serves as a low-cost alternative to the ADDAC800X High-End Outputs module, which ADDAC System has redesigned using a smaller low-cost transformer that also reduces it’s depth — making it perfect for more shallow Eurorack cases.
Features and Specifications
- Two independent output channels
- LIFT/FLOAT/GND toggle switch
- Signal overload warning LED
- (2) XLR Outputs
- 6HP
4 cm deep 40mA +12V 40mA -12V
ADDAC711 Balanced Inputs
While the ADDAC710 is designed to protect what goes out of your modular, the ADDAC711 protects what comes in. Using a dual channel Isolated DI box, the ADDAC710 keeps your modular free of undesired noisy interferences by providing galvanic electrical isolation from external sources while preventing ground loop induced hum.
Similar to the ADDAC710 at the output stage, the ADDAC711 also uses an impedance matching transformer that operates in the 20 Hz to 20 KHz range, while providing two fully balanced outputs (via XLR connectors).
Features and Specifications
- Two independent channels on the module with audio output
- Signal overload warning led
- LIFT/FLOAT/GND toggle switch
- Gain control XLR Input
- 6HP, 4 cm deep 40mA +12V 40mA -12V
The ADDAC710 and ADDAC711 modules are available now and priced at €160 and €240 respectively. For more information, please visit the ADDAC System product page.
