Realizing that there are some customers who will not want to get into the intricacies of
the manual EQ set-up straight away, Velodyne equipped the SMS-1 with a couple of
automated EQ set-up modes to minimize the effort required.
In order to use the simplest of these, the Self-EQ mode, you strictly only need to hook up
the microphone to the SMS-1 and the LFE output to the subwoofer. However, I would
always recommend connecting the video output to your TV as well. That way, you can
monitor the sweep level on-screen to ensure it is not too low, or flat-lining along the top
of the plot. You can then adjust the subwoofer gain to compensate accordingly.
To engage the Self-EQ mode, all you do is press the sequence 3-2-1 on the remote
control while at the initial OSD display. The display will change to the sweep screen as
follows.
The EQ sliders are reset to the standard 1/3 octave frequencies, and the SMS-1 then
perform 25 sweeps, moving individual sliders up or down to try and achieve a flat
response. Since the ear typically struggles to discern variations smaller than
±
3 dB at
these low frequencies, the SMS-1 stops moving sliders when the response is within these
limits. When it has finished, it saves the settings and returns to the initial OSD page.
Note that only the subwoofer output is in play during Self-EQ. No EQ Output signal is sent
to the receiver/SSP, so the main speakers produce nothing.
My system response following Self-EQ appeared as follows.
