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 top and bottom mic'ing 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.
