The remote jack on the back of DAC4800A and Cherry amplifiers allows you to force the unit into standby from an external source to save power. Some home theater systems have a control signal output that can be used to control the amp's standby operation.
The input takes less than a milliamp to drive. When the input is below 2V, the amp is placed in shutdown. When it is above 3V, the amp is active. When the input is not connected, the amp is active in the case of the Cherry, or controlled by the user in the case of the DAC4800A. The DAC4800A has a pushbutton standby control, and external control overrides the user setting. The Cherry series of amps does not have a pushbutton standby control.
The plug is a stabndard 2.5mm size barrel type, typically used by "wall warts".

A Few Words About Output Current
The output devices in the DAC4800A and Cherry amps are capable of pulsed drain current of more than 150A! However, the output stage cycle-by-cycle current limit is set to about 30A instantaneous.

INTRO
I'm the founder of Digital Amplifier Company.
On our web site, we explain that we don't go to trade shows or pay for standard print or web advertising. Do you have any thoughts on this?
This post is to get feedback about our products. If you have auditioned or purchased either of our current products, please give us a shout.
This post is to get feedback about our products. If you have auditioned or purchased either of our current products, please give us a shout. The DAC4800A is a 1000W amp and the Cherry is a 1200W amp. They are both 2-channel units and have very respectable specs (<0.009% distortion, near 120dB SNR). Some have said that our amps are the best they have ever heard regardless of price. Reviews are posted on our site and on Amazon.com (we sell there too).
Please let us know if you have heard one of our amps or if you have visited our web site (www.DigitalAmp.com). I'd like to get some feedback ASAP, especially concerning comparisons with other high end amps. We plan to introduce some new stuff soon as well.
I'm offering my expertise regarding digital (Class-D) amps since I have been designing them since the mid 1980s. If you have questions about these designs, let me know, and I'll try and answer them.
If you are only a casual music listener who thinks low bit rate MP3s on your iPod are the best in audio, please refrain from commenting!
Thanks very much.
