JK Audio RAMP3
Portable Stereo Headphone Amplifier

RAMP3

JK Audio's RemoteAmp Three provides a listen only connection for IFB or full bandwidth audio monitoring.  The XLR line level input accepts either a balanced mono signal or a one or two channel party-line intercom feed (listen-only).  The XLR source switch selects between balanced input and intercom monitoring.  The intercom mode allows RemoteAmp Three to work with one or two channel intercom systems, and provides separate volume controls for each channel.

The integrated speaker is disabled when headphones or earphones are connected.  The 1/2 watt, 1/4" headphone jack will cut through any crowd noise without distortion. Connect a mono IFB earpiece or stereo headphones to the 3.5 mm earpiece jack.

RemoteAmp Three is powered by one 9-volt alkaline battery.  If intercom power is available on either pin 2 or 3 of the XLR jack, this power will automatically override the battery, but will not charge the battery.
