User Guide
The screen will turn off while recording according to the
screen timeout setting of the AK media player used in conjunction
with the AK Recorder. Lightly touch the screen to turn it on again.
When using features such the limiter or low-cut filter, the
user must set the detailed settings according to the recording
subject or environment before use. Settings that do not
match the recording subject or environment may adversely
affect recording quality.
The limiter and low-cut filter functions cannot be used when
the recording format is set to DSD or greater than 352.8 kHz.
Certain features may not be available when recording.
Attack Time (signal compression time) refers to the time
that the limiter is operating, and the Release Time sets
the time the limiter is released. Default values: Threshold -
4dBFS, Ratio 1:20, Attack Time5 ms, Release Time 200 ms.
Low-Cut Filter (High-Pass Filter):
Enable or disable the low-cut filter function,
and set the frequency and slope values.
The low-cut filter function can effectively
remove low-frequency sounds as
well as resonant sounds in the
environment. The slope can be set from
6 dB to 24 dB, and the frequency can be
set from 40 Hz to 240 Hz in units of 10 Hz.
For example, if the slope and frequency
are set to 6 dB and 50 Hz, respectively, low-frequency sounds
of less than 50 Hz are reduced relative to a 6 dB slope.
Default values: Slope 6 dB, Frequency 40 Hz.
Phantom Power: Enable or disable the phantom power function.
Channel Selection: Select stereo or mono.
AES3 Format: Set the recording format to 16-bit or 24-bit when
recording audio from an external source connected via AES3.
Recording is performed through AES3 based on the selected bit value.
Peak Hold: Select whether to manually or automatically
maintain the maximum value of an input signal.
