This encodes a single mono bitstream using a single audio input (the audio on
channel A).
L3 mono offers 15 kHz audio frequency response if the Sample Rate is set to 32
or 20 kHz audio frequency response if the Sample Rate is set to 48 kHz.

HOT TIP!
If you wish to feed a mix of the audio on channels A and B, you can do so by setting up the
send mixer section (MX/MXP models) appropriately, or by setting the Send Mix option to "A
+ B" in the AUDIO menu (non-mixer model).
AAC‐LD Stereo
AAC‐LD Joint
These work similarly to the equivalent Layer‐3 modes (see above). These (and
the other AAC‐LD modes) modes are important since they offer significantly
lower delay than any mode other than G.722.
Offers 14 kHz audio frequency response.
AAC‐LD Mono
This encodes a single mono bitstream using a single audio input. Encodes the
audio on channel A. Offers 16 kHz audio frequency response.
AAC Stereo
AAC J‐Stereo
These work similarly to the equivalent Layer‐3 modes (see above).
Offers 15 kHz audio frequency response, when the sample rate is set to 32 kHz
and 20 kHz response when the sample rate is set to 48 kHz.
AAC Mono
This encodes a single mono bitstream using a single audio input. Encodes the
audio on channel A. Offers 15 kHz audio frequency response when the sample
rate is set to 32 kHz and 20 kHz response when the sample rate is set to 48 kHz.
