It’s easy to interface theTUBE MP with other equipment. All connections are made at the back of theTUBE MP. Standard XLR and
1/4" inputs and outputs make patching simple. Note: For best
audio quality, always use high-quality cables.
IInnppuuttss
The TUBE MP provides both an XLR and 1/4”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 l/4” input jack for
instrument applications.
XLR pin configuration: pin 1 = gnd pin 2 = Positive (hot), pin 3
= negative.
Do not Use both inputs at the same time.
OOuuttppuuttss
The XLR output of theTUBE MP is active balanced You may “se it
in an unbalanced configuration without harm to the output circuitry. Use the unbalanced 1/4” jack for sending your signal to
amps, processors or other unbalanced configurations. Also, both
outputs may be used at the same time.
PPoowweerr
Insert the supplied 9 Volt AC adapter’s plug into the input labeled
Pwr, 9VAC on theTUBE MP’s back panel.
The TUBE MP is powered by an external 9VAC adapter. 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 AC adapter in the rain or in
wet locations. lf the AC 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. Refer to the label on the adapter
or the specifications later in this manual for the appropriate operating voltages.

When power is applied to the TUBE MP the Power/Peak L.E.D.
lights green. This L.E.D. also serves as the signal clip indicator. If
too much signal is present this L.E.D. lights red. If the L.E.D. is
constantly lit, reduce the signal level with the Input Control. The
clip L.E.D. is positioned at the tube's output in the circuitry and
lights when a level 6dB below hard clipping dB is reached.

A RT’s TUBE MP circuitry is a hybrid design utilizing the latest and
best solid state and tube technology, Using a transformerless
design throughout the TU BE MP maintains cxccptional signal
mtegrity and extremely low noise. T h e active balanced input utilizes a hybrid multiple paired transistor/opamp design providing
extremely low noise and excellent CMRR. The instrument input
has a high impedance preventing the loading of any device connected to it. Phantom power is derived from the incoming AC
voltage. The XLR output is active balanced and the 1/4" output is
unbalanced with a 300 ohm impcdance.
AApppplliiccaattiioonnss::
The main application of the TUBE MP is a microphone preamplifier. Plug any microphone directly into either input and set the
Input and Output controls to provide a healthy level into the next
stage of your system.
Use the TUBE MP as an acoustic or piezo pickup preamplifier to
run directly into a console, amplifier, signal procesor or recorder.
You may use the TUBE MP to interface any instrument directly to
a live or recording console’s line input, amplifier, signal processor
or recorder.
The TUBE MP may also be used as a direct box.

The input control sets the amount of input Gain of theTUBE 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 +6OdB and +6 to +4OdB. Selection of the gain
range is made with the +20dB Gain Switch.

Use the +2OdB Gain/Norm switch to set the gain range of the
Input control. When the witch is out, theTUBE 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
applica-tions, where more level is needed, push the witch in.

Use theTUBE 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
PPhhaassee RReevveerrssee//NNoorrmm SSwwiittcchh
To set the phase of the TUBE MP’s output signal, “se 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.

The output control sets the output level of the TUBE MP. When
the control is fully counterclockwise the output level of the TUBE
