7. Do the speakers require a break-in period?
Nearly all new speakers require a few hours of bass-heavy
material at a fairly loud volume to break them in. What this
does is loosen up the driver suspensions and smooth out the
response. The speakers were designed and calibrated to
include the effects of break-in and will sound even smoother
afterward.
8. When I turn my speaker on, I get no sound for about 4
seconds. My old monitors work right away. What gives?
There are two "computers" in the ProLinear DSP that take
time to initialize before the speaker starts operating. Most
conventional active speakers have no digital signal processing,
and as a result, don't have to go through this process. Think
of it as similar to turning on a PC or Mac; there’s a “boot-up”
period.
9. When I change programs, I hear clicks and pops
occasionally. Is my speaker broken?
It is not unusual to hear slight noises when changing
programs. This is due to the discontinuous nature of digital
audio, and is most likely to occur when the programs are very
different.
10. When I change programs with the ProLinear DSP’s
PC application I get loud pops. What's happening?
Another application you are using may have configured the
serial port of the PC improperly. In particular, the Flow
Control must be set to "None." Exit any other application that
may be misappropriating the serial port. Refer to the technical
documentation regarding configuring the serial port within
your PC’s operating system.
11. The LCD display occasionally flashes red. What does
that mean?
On start-up, it's the internal processor performing its
initialization routine. This is normal. If it happens during
routine operation, it means the amplifier is clipping. The input
source volume or the Input Gain control should be reduced.
12. Can I do a “bulk dump” of the User Programs from
the ProLinear DSP into the PC application?
No, but there’s a workaround. After connecting the PC and
the ProLinear DSP system via the serial cable(s), call up the
User Programs from the ProLinear DSP speaker in question
one at a time, making sure they show up in the EQ Curve
space (the green window inside the EQ tab). Then save them
one at a time to the PC using the Save To User button and
location switch. Then save the Workspace, which contains all
the User Program settings, so you can recall the entire bank in
the future.
