USING THE AUTO EQ SETTING

Placing Measurement Microphone for MAIN EVO Loudspeakers

For simple applications of up to two EVO loudspeakers hooked up to OUTPUTS 1A and 2B (the MAIN OUT outputs), optimum placement of the Measurement Micro- phone is illustrated in Figure 10.

The placement follows a simple height-to-depth ratio of 1:2. For a given loudspeaker height the optimum position is a distance twice the height away from it, into the listener area. For instance, if the speaker is 10’ in the air, measure 20’ into the listening area and place the microphone there. It is very important that the Measurement Microphone remains on the central axis of the room or listener area, equidistant from each loudspeaker. See Figures 11 a, b, c.

A rough rule of thumb is that the Measurement Microphone should remain equidistant from both loudspeakers at a point approximately 2/3rd the length of the listener area away from the loudspeakers.

For optimum result please also make note of the type of floor in the listening area and follow the guide below in Figures 12a and 12b.

Soft surfaces - Measurement Mic on a stand at least 6’ high.
