With Neuman's MA 1 calibration system you get a stationary speaker system with perfectly optimised frequency, phase and impulse response according to scientific criteria. Due to its independence from a computer, such a system is also of interest to discerning hi-fi connoisseurs and is even a fairly low-priced alternative to high-end systems in the hi-fi sector.
For correct operation of the Neumann Monitor Alignment Kit 3, in addition to the included loudspeakers, a LAN cable is required for the control of each DSP device, as well as 2 XLR cables and 2 75Ohm BNC cables for connection of the loudspeakers. Your DSP-controlled Neumann devices are connected to your computer, if necessary by means of a network switch, and an appropriate number of LAN cables. The LAN network is only required for the calibration process; after calibrate, the EQ and delay curves are stored in the DSPs and the network can be disconnected again.
The MA-1 measurement microphone is operated for calibration at the microphone input with 48V phantom power of the same audio interface to which the loudspeakers are connected. If the system is to be set up using the digital input on the subwoofer/speaker, a digital audio output is also required on the interface. However, the use of the digital inputs is only supported with the LAN-capable KH 80 DSP. The digital inputs of KH 120 D / KH 310 D drive a DSP module, which is not required for the otherwise analog speakers in combination with the Monitor Alignment Kit. In this case, use the analog XLR connectors.
All in all, there are several possibilities for the connection from the interface to the box(es):
Detailed documentation and the required, free Neumann Automatic Monitor Alignment software are available in the Neumann download area.
Please be sure to switch off the Direct Monitoring function on the interface during the calibration process; otherwise you risk damaging your loudspeakers by creating a feedback loop! To do this, turn the source selector from Input to DAW, if necessary.
This task can also be performed by a suitable resistor network (T-element).
