The ACL Audio Interface can be used to connect a modular system with equipment like a mixer, a sound card or an effects unit. Line signals are fed to the module via two balanced XLR connectors. A potentiometer allows level adjustments in the range of full attenuation to unity voltage gain (0 dB). Results are emitted via two mini jacks. A LED indicates clipping. (Threshold: 4.5 Vpp)
The other way round, modular signals can be fed to the Audio Interface via two mini jack inputs. Subsequently, the material is processed by a volume control stage. Results are emitted via two balanced XLR connectors. Here, the level potentiometer’s range goes from full attenuation to +6 dB. Again, a LED is used to visualize clipping. (Threshold: 4.5 Vpp)
Furthermore, there is a stereo aux input, which can be routed to either the XLR to mini jack channels or the mini jack to XLR channels. Besides a level knob, the auxiliary input features a mute function.
Beyond that, the Audio Interface offers a headphone connector with level and mute options. It can be used to monitor either the XLR to mini jack channels or the mini jack to XLR channels.
