"Adjustable gain control provides up to 10dB reduction of signal" Means adjustable from -10 db REDUCTION to +30 db amplification? Or +20 to +30?

It isn't an even 30db gain on all channels, none of them are. It does vary, but 30db is max. The control can reduce the gain up to 10db from the max it's capable of on any given channel. It's a good amp, improved our reception and we gained a couple of channels.

Pull out the tubes with a gentle rocking motion, flip the unit over and remove the baseplate. Near the front of the amp (near the volume knob) there are two red boxes with two white switches each. The switches can be set to on or off. The switch settings have to match. There are four possible settings, off off, off on, on off, and on on. Depending on the switch position you can control the gain from +3 to +10. I have found that the higher the gain setting, the brighter the sound. You should try all settings to see which is best.

I would add to the others that it sound neutral when the EQ bypassed. However, the EQ bypass only bypasses the EQ. The gain on each channel is not bypassed.

4 chanel with a min 150 watt rms rating, should do the trick, bigger is better you can always turn the gain down

I didn't see any channel selection on mine. Maybe they mean something inside, like 6 frequency ranges. The amplifier didn't work for me because it amplified surrounding noise as much as what I was listening to.

Yes, you can always turn down the gain if it's too loud. The general rule is a 8" sub is good for a small bedroom(150 sq ft), 10" sub is good for small living room or large den(200 sq ft). The 10" also has a lower end that will shake the house.

Personally, I set the gain at about 3/4 no more. With amplifiers maxing out the volume typically adds distortion which creates poor sound and overdrives the amp. I set the frequency at about 150 or so for music, 120 for movies.

You can move it forward or back to a limit. I don't remember the numbers butHere is the manual: http://www.equalizerhitch.com/Equal-i-zer%20Support/installinstructions.php

I'm assuming you meant the AF gain controls. Yes, the amplifiers are on 2 boards separate from the input board. Some creative engineering should work on that. There are two separate amplifiers and two power transformers which makes this amp nice.

The foot switch is just an Active or Bypass switch, not a variable volume peddle. The Active volume is set by the GAIN pot, Bypass is straight through.

Hello and yes, a reduction of 29 Db. The reason I bought these is because I have used them at work for the last 30 years and they do the job! I've tried different types, kinds and these work the best.

It just amplifies what goes into it, the frequency response is pretty flat unless you change the EQ switch, and even then it's only a very slight increase in the 20-40 Hz range.

It is adjustable. I have 10 of them and I have set them to different voltages.

You can adjust the volume and gains. I've used this amplifier behind a PC headset jack (Apple MacBook Pro and Lenovo W530), Bose PC speaker jack (powered), and behind a Onkyo receiver. If already amplified, it's more important to adjust the gains and volume level to compensate but it's very simple. In all cases the sound qualified was significantly improved and the only time it didn't make a noticeable difference was behind a DAC which says a lot.

Each patch has a level control in the amp effect. That's what I found to control volume. It also depends on what effect the patcha has. For instance, a patch will be louder than another one if the gain is higher on the amp setting or a boost effect is on.

Yes.. see the measurement range indicated in the specifications. The range is given as 30dBA - 130 dBA. Use of the dBA indicates the decibel measurement range (dB) are given in A weighted measurement readings.

Hey, i bought one a few months back and it came with the 10amp which is kinda small. It doesnt sound bad, it has -bass, middle, treble, a gain control and boost control along with the volume. The 20 would probably have better output if you can get it, the 20 was not offered when i got mine. Hope this helps, Thanks Michael P.
