Live sound: How to set the levels on the power amplifier

The level control on your live sound power amplifier is, in most cases, a purely passive device. It doesn''t control the gain of the amplifier - it controls the level of the incoming signal before it goes to the amplifier circuit. All it can do therefore is make the input signal

Correct sequence/way to turn on and off audio

The monitors should be powered on last, and powered off first. The reason for this sequence: some audio electronics produce loud pops when you switch them on or off. Amplifiers and powered speakers often (but not always) are designed to

Is It Bad to Leave AV Receivers and Amps on All the Time?

The old tube system would have a surge of power that went straight to the cold heater elements. Each time the surge happened, it would shorten the life of the equipment. With the turn-on power surge for our modern equipment, the life-shortening effects are negligible.

Where should my power amp volume be, relative to preamp volume?

I have a Hood 1969 Class A amp with a volume knob. I''ve mostly been using it all the way up, and adjusting volume with a Schiit SYS passive preamp. The thought is that with the power amp volume all the way up, I''m converting the most energy as possible, to

Setting gain on a power amp | Audiokarma Home Audio Stereo

Not sure this is so much exclusively a tube issue. Here''s the question. Some power amps have gain controls ( I think more so in the past). Old and new Preamps have had different output voltages. Also if you''re running mono blocks you''d want to have levels match. So the question is, is there...
