Moderator: Welcome to PSW Church Talk, and welcome Dale.

Dale Alexander: Thank you, Gary.

Moderator: Dale, please give us your professional background.

Dale: I am a Senior Consultant with Acoustic Dimensions in Dallas, and I have a BSEE degree from Oklahoma State University. Married for almost 30 years with two great kids.
I’ve been at Acoustic Dimensions for over 6sixyrs and have had a great time.

Tim: BSEE?

Dale: Bachelor of Science in Electrical Engineering.

yam4000vca: Not much touring, I see :)

Dale: No, not much touring, however I did own my own small sound company in a small southeast New Mexico town for most of the ‘80s.

Jack: What are some of the more interesting projects, from a DSP standpoint, that you've worked on lately?

Dale: As with most consultants, the more interesting projects involve (Peavey) MediaMatrix. We’ve done several large church jobs with LCR (left-center-right) systems that require the power of MediaMatrix.

CharlieH: What are your primary functions at Acoustic Dimensions?

Dale: I am a system designer and project manager.

Bill: What kind of DSP chips work best in audio applications?

Dale: One of the more interesting jobs I have designed recently was a custom (EAW) KF900 system in a 5000-seat church in Austin, TX. I personally like the Shaark chip from Analog Devices. However, any quality chip with floating point capability is going to work OK for almost any sound application.

Tim: Which provides the most power?

Dale: The Shaark and the new Motorola chip are both very powerful. Several manufacturers are using both of them. I think QSC uses the Motorola and White and Symetrix are using the Shaark.

GW: How do you chooses a DSP box for an application?

Dale: That is a very good question. First, we evaluate the needs of the client/job and decide what kind of system is required. Then we decide on the type of DSP platform
is required to achieve the specified goals.

John: Have you used products like Crown's IQ DSP card that plug into the back of their amps? And, why or why not?

Dale: At AD (Acoustic Dimensions), we have used most of the devices out there and have developed opinions that we would rather keep to ourselves. However, I will say that the software to program and access the DSP is very important and has to function flawlessly.

EDDY: What are some common-sense DSP boxes for medium to smaller church applications?
