INTRODUCTION The Auto-Tune Pre combines an ART tube preamp channel with integrated Antares® Auto-Tune® processing in a compact easily accessible package ideal for studio or stage. Now live artists can easily add high quality Antares pitch processing without the complexity and cost of an external computer and software. The Antares Auto-Tune EFX section of the product is designed to have a user interface and functionality that is similar to the Auto-Tune EFX Plug-in software.
CONNECTIONS The INPUT “Combo” jack allows for either XLR or ¼-inch TRS input connections. The XLR input connection is used primarily for balanced microphone input. Pin 2 is positive, pin 3 is negative, and pin 1 is ground. +48 Volt phantom power (when enabled) is supplied to pins 2 and 3. Pin 1 acts the ground return. Do not lift pin 1 when using phantom power.
The ¼-inch MAIN OUTPUT jack is unbalanced with an output impedance of 300 Ohms. The maximum output level is +18dBu. The XLR MAIN OUTPUT jack is balanced with an output impedance of 600 Ohms. The maximum output level is +24dBu. It can provide clean balanced signals for long cable runs. The 9 Volts AC power connector on the rear should only be connected to the power supply that comes with the unit (9 Volts AC @ 1000 mA). Make sure that you specify AC and not DC if you have to replace this supply.
CONTROLS AND OPERATION PREAMP SECTION CONTROLS The GAIN control directly adjusts the input amplifier’s gain, giving you control over the dynamic range of your source. You get from 0 to 48dB of gain depending on settings. Set this control counterclockwise to minimum gain when first connecting the input jack. The GAIN switch adds 20dB more to the preamp gain. This is useful when you need more gain than the input GAIN control can provide. LED metering circuitry aids in setting gain.
AUTO-TUNE SECTION CONTROLS The Auto-Tune section is designed to have a user interface and functionality that is similar to the Antares® Auto-Tune EFX Plug-in software. Users can select the Key, Scale, and EFX type. Individual notes can be toggled on or off using the Note key pads for more customization. Bypass and Preset switches enhance live operation. AUTO-TUNE SECTION SETUP First, set the Key by pressing the KEY button. You can cycle through the top row of 12 LEDs as you continue to press this button.
current Preset. The Preset LED will flash momentarily to let you know that the new settings are being stored. The state of the BYPASS switch is also saved with the preset information so any preset can be recalled in bypass mode. The PRESET switch and 5 Preset LEDs are designed to enhance live operation. Momentarily pushing the switch cycles through the 5 presets. Whatever Auto-Tune settings were indicated when you last saved a particular preset are recalled the next time that you go to that preset.
