IN (1/4” jack X 2) For input of the signals from the sources. The sources may be the outputs of any type of musical instrument or amplifier speaker output. (WARNING! When connecting to speaker outputs, the Direct2 does not supply the proper amplifier load required by most tube type amplifiers. Do not use a tube amplifier’s speaker output alone with the Direct2. You must also have a speaker or appropriate dummy load connected to avoid possible damage to the amplifier. OUT (1/4” jack X 2) A “Y” connection or “loop through” from the input. OUTPUT 1, OUTPUT 2 (XLR jacks) Male XLRs, which provide balanced low impedance (150 Ohms) signals suitable for connection to balanced, low-Z equipment (mixing console, workstation, etc.) PAD (Switch X 2) Most instruments will operate properly when set to the OUT position. Set to the IN position (applies an extra 20dB of attenuation) for use with very “hot” instrument signals or when connecting the Direct2 to the speaker output of an amplifier. GND/LIFT (Switch X 2) Disconnects the ground between each input and the corresponding XLR output when set to the LIFT position to help eliminate hum. Ground remains connected when set to the GND position.
