Digit Digit Meaning
2 1 Speaker Over Current. (Short Circuit on amplifier output). Contact Authorized Service
Representative.
2 2 Speaker Over Temperature. (Heatsink temperature too hot). Reduce level to allow speaker to
cool. Contact Authorized Service Representative if problem persists.
2 3 Speaker Under Current. (Open circuit on amplifier output). Contact Authorized Service
Representative.
2 4 Speaker Supply Voltage Error (either 3.3V or +/-15V). Contact Authorized Service Represen-
tative.
2 5 Speaker in Boot Loader Mode. Contact Authorized Service Representative
3 1 Error communicating with Speaker. Check connections between EVOi.net and EVOi.324.
3 2 Loudspeaker gone off-line during a set up operation. Check connections between EVOi.net
and EVOi.324, and power connections to EVOi.324.
3 3 Speaker Data Corruption. (Parameter Settings in Error). An error has occurred that resulted in
an invalid parameter set. EVOi.net will attempt to update after error is cleared. If error
persists, contact Authorized Service Representative.
3 4 Power-up data disagreement. Usually caused by connecting a different EVOi.324 to a
EVOi.net output. (See Appendix, Power Up Operation page 25).
3 5 Backup data has been restored. If primary parameters are corrupted, a backup set is substituted
output. (See Appendix, Power Up Operation page 25).
3 6 Default data restored. User restored defaults by pressing 3 large keys on front panel output.
(see Appendix, Power Up Operation page 25).
3 7 Speaker Muted by user. Feature for future development.
4 1 Speaker DSP Failure. (No response from DSP ). Contact Authorized Service Representative.
4 2 Measure Microphone signal not present (shows on all channels). The EVOi.net Measurement
Microphone was not connected, or the cable is defective.
4 3 Measurement Level Error. (Input too quiet during Auto EQ/Delay setup.) The chosen location
is too far away from the loudspeaker for an accurate determination of the system response.
Move the microphone forward and try again. For accurate results, the microphone should
typically see a level of 85dB +/- 2dB. (This limits distance to speaker for Auto EQ to about
17m (or 56 feet) in a non-reverberant room). It should be noted that background noise level
will alter this threshold slightly.
4 4 Auto measure polarity reversal. The cable between the EVOi.net Measurement Microphone is
incorrectly wired (polarity reverse in the cable). Replace or repair cable and try again. Also,
this may occur if the Measurement Microphone is placed behind the loudspeaker cabinet or is
too close to a large wall. Reposition the Microphone. Clear the error and try again.
4 5 Speaker Impulse Response in Error (during AEQ/Delay setup). The microphone is placed in a
poor location that is not accurately receiving the speaker signal. Move the Microphone.
4 6 Auto measure Delay too long (after AEQ/Delay setup). The system has measured a delay that
exceeds its ability to adjust the internal delay.
