I'm installing a sound system in a pizzeria restaurant that will be

Why did you do this? You could have got standard installed sound speakers
for less money.

I'm at a loss as to what receiver/amplifier I need to accomplish the
following requirements:

1) Be able to connect 4 speakers
2) Two volume controls. One for each set of 2 speakers.
3) Should have connection for both a CD player and computer via mini
jack to RCA converter.

Basically, you don't want a receiver. You want an amplifier with a 70V
output, mono.

Then you want an attenuator on the front two speakers, and an attenuator
on the back two speakers.

You will have to add 70V transformers to them if you wish to use those
Pyle things.

There is a good introduction to 70V systems in the Yamaha Sound Reinforcement
Handbook. It allows you to switch speakers in and out easily without any
change in level to the other speakers, and to adjust levels independently
by doing the level control after the amp rather than before it.

The Speco transformers and attenuators are okay and cheap. The Atlas ones
are better and less cheap. The Tannoy ones are excellent and expensive.

I'm looking at the Pyramid PR530A (see link below) Can you tell me if
this has the above

I would not wish this stuff on my worst enemy. Look for stuff designed
for installed sound applications.
