Frequently Asked Questions
4
It is impossible to design a speaker that fulfills the
requirements for every situation, but hopefully the ProLinear
DSP will give you a versatility approaching that. The
following information will hopefully help you decide what is
the best way to set up the speaker.

Basic FAQs

1. Can I play the speakers through the serial port of my
PC?
No. The serial port is only for EQ and level control.
2. Does the ProLinear DSP accept digital inputs?
No, it only accepts analog audio signals.
3. Can the ProLinear DSPs be placed on their sides?
Yes. It does change the speaker sound field to some extent as
you move in a horizontal direction, as would occur with any
speaker, so slight adjustments to placement and EQ might be
required. But the sonic characteristics of the speaker remain
pretty much the same.
4. Can I place the ProLinear DSP against a wall, or in a
wall?
Yes. But the rear heatsink should be given adequate
ventilation. If the amp overheats the speaker will temporarily
shut down to protect itself. It will be explained in another
FAQ that when the speaker is placed in a wall, the frequency
response will change, so this must be taken into consideration.
5. Do I have to connect the serial RS-232 cables to get the
speaker to work?
No, the speakers will work just fine without these connections.
What they would do is give you the added capability of
controlling multiple speakers from the front panel of one
ProLinear DSP. They also allow you to control the speakers
with a PC using the supplied software.
6. Can I use this speaker in a 5.1 monitoring setup even
though I don't have a sub-woofer?
Absolutely. The ability to chain the speakers to a PC gives an
added dimension of control not available with most surround
speakers. The only issue at present is bass control. While the
ProLinear DSP has an extended bass frequency response,
there may be some applications for which a sub-woofer may
be desired.
