Product Description

ART's TUBE MP circuitry is a hybrid design utilizing the latest and best solid state and tube technology, using a transformerless design throughout the TUBEMP maintains exceptional signal integrity and extremely low noise. The 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 ¼-inch output is unbalanced with a 300-ohm impedance.

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.

DO NOT USE BOTH INPUTS AT THE SAME TIME.

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.

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 counterclockwise the output level of the TUBE MP is zero. Turning the control clockwise increases the level of the output to a maximum of +10dB of gain. This gain is in addition to the existing input gain.

Power/Peak LED

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

Applications

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 processor 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.

SERVICE

The following information is provided in the unlikely event that your unit requires service.

Be sure that the unit is the cause of the problem. Check to make sure the unit has power, all cables are connected correctly, and the cables themselves are in working condition. You may want to consult with your dealer for assistance in troubleshooting or testing your particular configuration.
If you believe that the ART unit is at fault, go to www.artproaudio.com .
Select "Support", then "Return Authorization Request" to request a return authorization number.
If you are returning the unit for service, pack the unit in its original carton or a reasonable substitute. The original packaging may not be suitable as a shipping carton, so consider putting the packaged unit in another box for shipping. Print the RA number clearly on the outside of the shipping box. Print your return shipping address on the outside of the box.
Include, with your unit, a note with the RA number and your contact information, including a return shipping address (we cannot ship to a P.O. box) and a daytime phone number, and a description of the problem, preferably attached to the top of the unit. Also include a copy of your purchase receipt.
