PRIOR TO SETUP
Before Running AntEQ
The following guidelines will ensure a smooth and accurate setup procedure. Have the
MultEQ CD, microphone and LED available and take a note of the conditions below
as they are needed in the next section. Some type of stand is also needed to place the
microphone at different locations in the vehicle. A clip or tape is not always a good
idea as not everyone's ear can be stuck to the headliner or clipped to the visor. The best
locations are where a head is most likely to be found (along with its accompanying
body).
1. Determine the factory system's output type (full-range or two-way). If you know
that your vehicle has tweeters mounted in the dash or door panels, the Factory Radio
probably has two-way outputs.
In the case of a two-way system, make sure the tweeter output goes to the L1/R1
inputs and the low output goes to the L2/R2 inputs. At this time, decide the crossover
point for the high-pass speakers. Find the low cut-off point of the tweeters and
use that as the HP cut-off (5 kHz by default). The mid-bass low-pass cut-off is
determined by tweeter high-pass. If there is a subwoofer in the system, the low pass
cut-off will be set automatically by MultEQ.
If the output is full range, the factory radio output must go to the L2/R2 inputs.
2. It is recommended to start MultEQ calibration with the 1st MIC position in the
driver's seat and the 2nd MIC position in either the passenger's seat or in between the
two front seats. Just remember, the more positions that are included in the calibration,
the better the results will sound. MultEQ requires a minimum of 4 MIC positions and
has a limit of 8. The number and location of the MIC positions is left up to the user.
However, following the guidelines described here have been found to give the best
results.
3. PRESET 1 settings are derived from MIC position 1 and PRESET 2 settings are
derived from MIC position 2. The 3rd through 6th MIC positions should be grouped
where the driver's head would be positioned. The 7th and 8th MIC positions should
be in the rear seats.
NOTES:
• It is possible that poor MIC positioning could cause anomalies in the calculated
response curve. If this happens during the fi rst calibration run, try moving the MIC
positions 3 through 8 to more favorable positions.
• If using the AUX Input as the primary source for the EQ, the REMOTE ON wire
must be used. Otherwise, there is no way for the EQ to turn on. Use the Remote On
wire from the head unit or a source of switched ACC voltage (Ignition).
