Two easy questions about NAD 7020..

I just picked up a NAD 7020 at the thrift store for $30.00. Great little reciver, my first piece of NAD gear.
(1) On the back, there is a PRE-AMP OUT, NORMAL IN, and LAB IN. What is the lab in? Jumpers currently go from pre -> normal.
(2) The low-level switch on the front, is this used to run the amp at higher dymanics at a lower level (I remember doing this on 100watt tube guitar gear, pull a set of tubes, more dynamic, lower volume) ? I won't use this reciever for very loud music, should I need low-level on and use most of the "volume?"
Thank you!

1. seems like NAD had a rumble filter or something on the normal in, the lab in does not
2. that's up to you, I use it all the time.Dodd - Battery Preamp
Monarchy Audio SE100 Delux - mono power amps
Sony DVP-NS999ES - SACD player
ADS 1230 - Polk SDA 2B
DIY Stereo Subwoofer towers w/(4) 12 drivers each
Crown K1 - Subwoofer amp
Outlaw ICBM - crossover

Where is the remote? Where is the $%#$% remote!

I ave a 7020 I bought new in '83. Not sure what the lab in is.
I use the low level switch most of the time as well. Gives you more precise volume control.
Great little receiver, you should enjoy it!
Great deal for $30. I believe I paid $350 in 1983.Signature goes here -
From my 7020 instruction manual
"Two sets of power amp inouts are provided. The LAB inputs have wideband frequency response extending uniformly from low infrasonic to high ultrasonic frequencies , and may be used for laboratory tests and special applications. The NORMAL inputs are equipped with infrasonic and ultrasonic filters to reject interference occurring outside of the audible frequqncy range, minimizing intermodulation distortion and preserving the amplifier's power for music"Signature goes here
