User manual ART TUBE MP

[. . . ] Outputs 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. Power Insert the supplied 9 Volt AC adapter's plug into the input labeled Pwr, 9VAC on theTUBE MP's back panel. [. . . ] 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. When power is applied to the TUBE MP the Power/Peak L. E. D. also serves as the signal clip indicator. If too much signal is present this L. E. D. is constantly lit, reduce the signal level with the Input Control. is positioned at the tube's output in the circuitry and lights when a level 6dB below hard clipping dB is reached. Product Description 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. 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 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. 4 5 A R T TUBE MP Specifications Dimensions Weight Input Connections Output Connections Input Impedance XLR, l/4" Output Impedance XLR, l/4" Maximum Input Level, XLR Maximum Input Level, 1/4" Maximum Output Level, XLR Maximum Output Level, l/4" CMRR Frequency Response Dynamic Range Total Harmonic Distortion (THD) Maximum Gains XLR to XLR 1/4" to l/4" XLR to 1/4" 1/4" to XLR Equivalent Input Noise (EIN) XLR to XLR l/4" to l/4" Power Requirements 5.
