User manual ART SGE MACHK II MULTI-EFFECTS

[. . . ] Sister to the ART Digital MPATM , the MPA GoldTM performs to incredibly high standards, and that it's tone, functionality and performance will satisfy even the most discerning user. [. . . ] Variation of the input impedance of a microphone preamplifier changes the load against which the microphone has to push. This variation dramatically alters the performance of a microphone, and creates numerous sonic possibilities for microphone performance. The variable impedance control of the MPA Gold is infinitely variable, as opposed to steps. This allows users much finer control over the tuning of the impedance. The meters act like a normal histogram for the average signal level and the display holds the highest LED on alone for one second. While the average level function attack and release are measured in milliseconds, the peak function has a 20 microsecond attack time. Additionally, the analog meter range is switchable between -10dB and +4dBU. The MPA Gold's High Pass Filter is continuously variable from 15Hz to 150Hz. [. . . ] The MPA Gold is truly a modern, world-class tube microphone preamplifier, and its audio performance will surely exceed your expectations. MPA GOLD FEATURES: Variable Input Impedance For Flexible Microphone Voicing (150 Ohms to 3000 Ohms) Selectable Tube Plate Voltage Large VU Meters with Range Switch Tube Warmth LED Meter Improved Discrete Class A Input Microphone Preamplifier Lower Noise At Low Gains, Wider Frequency Response and Lower THD Than our Pro MPA Front Accessible Instrument Input Jack With Very High Input Impedance Automatically Switches To Instrument Input When You Plug In From the innovative minds at ART.
