CONNECTIONS
It’s easy to interface the TUBE MP with other equipment. All connections are made at the back of the
TUBE MP. Standard XLR and ¼-inch inputs and outputs make patching simple. Note: For best audio
quality, always use high-quality cables.
Inputs
The TUBE MP provides both an XLR and ¼-inch input jack. Use the balanced XLR input for use with
a microphone. Audio input as well as phantom power (if needed switchable on and off) is supplied
through this jack. Use the unbalanced ¼-inch input jack for instrument applications. XLR pin
configuration: pin 1 = gnd pin 2 = Positive (hot), pin 3 = negative.
Outputs
The XLR output of the TUBE MP is active balanced you may “see it in an unbalanced configuration
without harm to the output circuitry. Use the unbalanced ¼-inch jack for sending your signal to amps,
processors or other unbalanced configurations. Also, both outputs may be used at the same time.
AC Power Hook Up
The Tube MP has a universal external power supply designed to operate at 100 to 240V AC ~ 50/60
Hz. Only use the adapter that came with the Tube MP. If the adapter becomes lost or damaged,
contact ART Customer Service for replacement. If you need to purchase one locally, refer to the label
on the adapter or the specifications later in this manual for the appropriate power specifications
Setting Up the Universal power supply
Insert the correct clip adapter to the supply according to country of operation. There are four different
clips included. Please attach the matching clip as per your AC power source.
Insert the supplied 12V DC adapter’s plug into the input labeled Pwr.
Always make sure the output plug is securely plugged into the rear of the TUBE MP, and that the
adapter is held firmly in an electrical outlet. Never operate the TUBE MP or power adapter in the rain
or in wet locations. lf the adapter’s cord is ever cut, discontinue use and replace the adapter with a new
one. Unplug the adapter when the TUBE MP is not in use.
CONTROLS, SWITCHES and INDICATORS
Input Control
The input control sets the amount of input Gain of the TUBE MP Turn the control clockwise to increase
gain and counterclockwise to decrease gain. You may control two ranges of gain with this control, +26
to +60dB and +6 to +40dB. Selection of the gain range is made with the +20dB Gain Switch.
+20dB Gain/Norm Switch
Use the +2OdB Gain/Norm switch to set the gain range of the Input control. When the witch is out, the
TUBE MP operates in Normal mode depressing the switch adds 20dB of gain. This mode is indicated
by the labeling in red and corresponds directly to the Input control’s red gain range labeling for
microphone applications, where more level is needed, push the switch in.
3
P-Pwr +48V/Out Switch
Use the TUBE MP’s phantom power to supply power to all microphones requiring +48V phantom power.
The TUBE MP's Phantom power is engaged and disengaged with this witch Phantom power is applied
to pins 2 and 3 of the XLR Input jack when this switch is pushed in. To disengage phantom power,
position the switch in the out position. Power Phase Reverse/Norm Switch.

Phase Reverse/Norm Switch
To set the phase of the TUBE MP’s output signal, adjust this switch. When the switch is in the Out
position the output signal is normal. Depressing the switch reverses the phase of the output signal. In
multi-microphone applications, mic placement can affect the phase of the signals If your sound is “thin”
or "out of position,” reverse the phase to correct the problem.
Output Control
The output control sets the output level of the TUBE MP. When the control is fully co
