Emtech Electronics EJ-2Plus - Manual

EJ-2 Plus Multi-Input Adapter
The EJ-2 Plus is an audio adapter that allows you to connect the audio output from your
laptop computer or other audio device to the input of an existing public address system. All
the cables are provided for connecting the audio from your laptop, cassette player, CD
player, DVD player, or video tape recorder to the microphone input of a PA system. The EJ-
2 Plus is the ideal companion for an individual making multi-media presentations. It is
small and lightweight so it can travel with you wherever you go.
Instructions: Simply make a connection between the audio output connector(s) of your
laptop or other audio device using either the 3.5mm stereo plug or RCA plugs attached to
Inputs A & B on the EJ-2 Plus, then plug the 3-pin XLR connector into any existing
microphone input of the PA system. You are now ready to make your presentation using
the EJ-2 Plus.
Volume control for the audio can be provided via the built-in potentiometer on the EJ-2
Plus. If you need additional volume you can increase the signal strength going to Inputs A
& B by adjusting the volume control on your laptop or other audio device.
The EJ-2 Plus also has a ground or hum switch. On occasion you may hear a hum or buzz
caused by a ground loop in the PA system. When that happens you can disconnect the
internal ground of the EJ-2 Plus with the slide switch.
The EJ-2 Plus is a passive device. It makes use of the power within the audio signal itself,
so you will never need batteries or an external power source while using the EJ-2 Plus.
