Mini•Me User’s Guide The New Compact Vision The smooth lines of the Mini•Me front panel begin to tell the story. Left and right input level controls feature a click stop at the far left that activates a preset line/cal level, set with multi-turn trimmers. Accurate LED indicators between the input level controls give a clear display of available headroom. Mic/Instrument Preamps The mic preamps are a high-quality design by the team that created our award-winning and widely praised Trak2 preamps.
Mini•Me User’s Guide Standard Interfaces The Mini•Me includes AES/EBU (XLR) and S/PDIF (RCA/coaxial) outputs which are available simultaneously, clocked by a high-stability reference crystal oscillator, making the Mini•Me an ideal master clock. Direct/Return Mix Monitor A comprehensive mono/stereo monitor section allows you to balance the direct sound you’re recording with audio returned via the USB port. Battery Power The Mini•Me ’s low power consumption makes it ideal for battery operation.
Mini•Me User’s Guide Quick Start Connect left and right analog inputs to the rear XLR or 1/4 in connectors. These inputs are to the far right as you look at the rear panel (If necessary, refer to rear panel diagram on p.11 for location. See below for detail on different analog sources and which input connection should be used.) Connect the digital output from the AES/EBU male XLR connector, S/PDIF female coaxial connector, or USB connector on the rear panel to your desired recording device.
Mini•Me User’s Guide *Note: When sending a line input into the Mini•Me, it is important not to use the 1/4 in inputs, as these inputs have additional gain, as is required for instrument inputs such as guitars or keyboards. If your source for line input is 1/4 inch, we suggest a 1/4 in to XLR cable to enable proper connection to the Mini•Me. Metering The front panel metering LEDs indicate the level of the input signal after A/D conversion.
Mini•Me User’s Guide USB Input & Output A Mini•Me equipped with the USB Option Card offers digital I/O for use with computer operating systems that support USB Audio devices. The audio can be handled in the operating system in different ways. Refer to your platform and OS below for detailed information on setup options for the Mini•Me. The Mini•Me also offers a unique feature that enables the unit to run at a different sample rate and bit depth than the computer recording software.
Mini•Me User’s Guide USB Audio with Sound Manager • Having connected the Mini•Me to your computer via USB, turn it on. To insure that the Mac recognizes the Mini•Me, go to the Apple menu and choose “Apple System Profiler”. Click on the “Volumes and Devices” tab. The Mini•Me should show up labeled “Apogee” as one of the USB devices. • • • • • Open the “Sound” Control Panel (in the Apple menu under “Control Panel”). Click on the “Input” tab. Choose “External Mic… USB Audio” Click on the “Output” tab.
Mini•Me User’s Guide • • • Connect the Mini•Me to the computer with a USB cable. Power on the Mini•Me. To ensure that the Mac recognizes the Mini•Me, go to the Apple menu and choose “Apple System Profiler”. Click on the “Volumes and Devices” tab. The Mini•Me should show up labeled “Apogee” as one of the USB devices. In your application, select the audio hardware preferences. Exactly what this looks like will depend on the application; the example shown here is from Logic.
Mini•Me User’s Guide correctly, but note that under Windows Me, the built-in drivers do not support 24-bit recording. We strongly recommend the use of the Windows Mini•Me ASIO driver. The same driver is utilized for all supported Windows versions. This driver offers operating system-wide support for the Mini-Me, allowing it to function correctly even with applications that do not use ASIO.
Mini•Me User’s Guide Soft Limit and Push-IT™ Soft Limit is an analog process that acts as a guard against digital ‘overs’ that can result from high-level transients in the incoming audio signal. When enabled, Soft Limit will round out peaks in the incoming signal in order to eliminate the undesirable effects of clipping the A/D converter chip. This rounding will begin on peaks at about –4dBFs and gradually smooth them out up to 0dBFs in order to safeguard the audio signal.
Mini•Me User’s Guide 3 (curve starts at –14 on the left axis) This shows the response curve of SLC setting Compression 3. Top switch in far right “SLC” position, bottom switch far right in curve “3” position. off (curve runs from the origin, bottom left, to +0/-0) Circuit bypassed. Top switch in far left “off” position. SL (curve runs from the origin to +2/-0) This shows the response curve of Soft Limit only. Top switch in center “SL” position. The bottom switch position is not relevant.
Mini•Me User’s Guide Applying the UV22HR Process UV22HR Encoding is best applied as the final step in the signal chain before the actual mastering device. Using the Mini•Me as the A/D converter to capture an analog mix to digital for Compact Disc, for example, you would set the word length to 16 bits. Notes • • • • Because UV22HR is essentially a “once only” process, we do not recommend that you use it more than once on a signal.
Mini•Me User’s Guide Analog Output Headphone Out: The headphone section of the Mini•Me is designed to offer flexible monitoring of the recording process. This output is a 1/8 inch mini headphone jack on the rear panel. You have the ability to monitor the analog inputs (before A/D conversion), the USB Audio return from the computer, or a mix of both signals. To monitor the inputs, turn the “Mix” knob on the front panel fully counter clockwise to the “Direct” position.
Mini•Me User’s Guide recording drums, explosive sound effects, etc. We suggest that you only change these jumper settings if you are actually experiencing overload conditions. Remove the top cover as described above. Now look to the rear of the unit, adjacent to the universal input connectors (see illustration below). You will see four pairs of jumpers, two pairs for each channel. You can configure each channel independently if you wish, but be sure to move all four jumpers for a channel.
Mini•Me User’s Guide 3. Pull the rear panel back (without removing it) to provide clearance for the USB Option Card connecter. 4. Insert the USB Connecter (on the USB Option Card) into the square cutout of the Mini•Me rear panel, ensure that connector pins under the card are properly aligned (indicated at right), and gently press the Option Card into place. 5. Secure the Option Card by installing the two provided screws in the locations indicated. Re-install the Mini•Me Top Cover.
