User manual ART DUAL MP

[. . . ] If no load is placed on the XLR input (no instrument or microphone connected) the front jack will function as if there was nothing connected to the XLR input. However, the two signals will sum and the signal present at the XLR jack will tend to attenuate the signal of the 1/4" input. Both balanced and unbalanced output connections may be used simultaneously. This is particularly useful when using the Dual MP as a direct box for instruments or line level signals. [. . . ] +20dB Gain/ Norm Switch Use the +20dB Gain/ Norm switch to set the gain range of the Input control. When the switch is in the out (Normal) position the gain range is +6 to +40dB. With most microphone applications you'll find using the Dual MP with the +20dB gain switch in is needed in most situations. Use the setting that best fits your application. **Note: Be sure to turn down or mute the output of the Dual MP when engaging or disengaging Phantom power. Additionally, when disengaging, allow 30 - 45 seconds for the power to completely dissipate. Most microphones will make a sound like air leaking from a tire when phantom power is disconnected, but some can make some very nasty low rumbles and whines as well. **Another Note: Dynamic microphones should not be affected or damaged if they are plugged into a line where Phantom power is present. Phase Switch The Phase switch is provided to reverse the phase of a signal. This switch works on Pins 2 and 3 of the XLR Output jack of the channel. In the Reverse (or "in") position, Pins 2 and 3 are reversed as the signal is changed to 180 degrees out of phase. In multiple microphone applications, the placement of the microphones can affect the phase of a signal. If two microphones pick up the same signal from different locations, the result can be a hollow or frequency "shifted" sound. In some cases it may sound as if an instrument disappears if it happens to be 180 degrees out of phase. Likewise, if a microphone cable is wired incorrectly, when used with a properly wired cable the signal will be out of phase. **Note: for single microphone applications switching the phase switch in and out will produce little to no change in the output signal. Special Effects For industrial, metal, or just "flavor" textures experiment with the Dual MP. Cascading the channels can produce overdrive and tube distortion that can add interesting textures when blended with vocals and different instruments. No harm will come to the Dual MP with this type of experimentation however, be sure to have output and monitoring levels turned 4 5 Output Control The output control sets the output level of the Dual MP. When the control is fully counterclockwise, there is no output. Turning the control clockwise increases the level of the output to a maximum of +10dB of gain. Design Overview A R T's Dual MP circuitry is a hybrid design utilizing the latest and most advanced solid state and tube technology. Using a transformerless design throughout, the Dual MP maintains exceptional signal integrity and extremely low noise. The Active balanced input utilizes a hybrid multiple paired transistor design providing extremely low noise and excellent CMRR.
