User Manual

Apogee Duet User’s Guide
1. Device Icon & ID Button (Mac only) - A device icon and ID button is placed adjacent to
each row of parameters to identify the hardware unit to which the row belongs. By
clicking on the ID button, the corresponding hardware unitʼs front panel will illuminate.
Each hardware unit is assigned a Peripheral Prefix which is displayed on the ID button.
2. Analog Level - Use this menu to select microphone, instrument, or line input.
3. Soft Limit - Use this menu to engage Soft Limit. Soft Limit is Apogee’s proprietary
analog process for taming transients before A/D conversion. By gently rounding
transients in a transparent manner, it’s possible to maximize level BEFORE the A/D
conversion stage. Soft Limit is most effective with signals with large transients such as
drums, percussion and plucked instruments. Soft Limit may not be the appropriate
choice for signals such as bass or organ.
4. Input Level - The gain of each input is controlled with these software knobs. The gain
level is indicated in the value box below the knob.
5. Analog Input Meter - This meter displays the level of the analog input after A/D
conversion.
6. Group On/Off - Use this to group the gain setting of both inputs so that the multi-
function knob on Duet or one software gain knob controls both input gains
simultaneously. If a gain offset is present between inputs when Group is set to On, this
offset is preserved.
7. Phase - Check this box to reverse the polarity of the input signal. Under certain
circumstances, when two mics are used on one source, reversing the polarity of one mic
may result in a fuller sound. For example, when a top and bottom mic is used on a snare
drum, a fuller sound is obtained when the polarity of the bottom mic is reversed.
8. 48 V / Phantom Power - Engage this button for 48 volts phantom power on the XLR
connections. Condenser mics require phantom power to operate.
