EAW Smaart 6 Operation Manual Applications

Figure 4-7 Sample measurement of an analog parametric EQ filter

4.3 Measuring a Loudspeaker

This example uses IR Analysis mode and the real-time Frequency Response display to

measure a loudspeaker in a room.

The following components are required:

• Amplifier and loudspeaker

• Measurement microphone with flat frequency response (preamp/phantom

power supply if the mic requires it)

• Cables and adapters to make the required connections, including one Y-cable

Connect the components as shown Figure 4-8.

• The output of the signal source (in this case, the computer output channel des-

ignated as Main Out Smaart) drives the power amplifier and loudspeaker, as

well as the Reference Input (Ref In) channel for Smaart.

• A measurement microphone is routed to Smaart’s Measurement Input (Meas

In). Smaart’s audio input and output devices and channel assignments are set

from the Audio I/O tab of the Options dialog (see page 98).
