Using the Internal Audio processing
RM1 features a full blown DSP and internally acts just like a mixing console including on-board processing. Delivering broadcast-quality sound, engineered by DHD audio.
Processing Chain / Signal Flow
Each input channel utilizes audio plugins, which can be configured by the user to optimize the incoming sound. The plugins are arranged in the following order of the audio signal passing them:
| # | Plugin |
|---|---|
| 0 | Gain |
| 1 | AGC |
| 2 | SubSonic |
| 3 | Expander |
| 4 | Var Filter |
| 5 | EQ 1 |
| 6 | EQ 2 |
| 7 | EQ 3 |
| 8 | EQ 4 |
| 9 | Compressor |
| 10 | Limiter |
| 12 | Panorama / Balance |
| 13 | Automix |
Channel Processing
Gain
Technically, the gain stage comes before any other processing step. It is used to amplify the audio signal. Also, phase inversion, 48V Phantom Power and auto level gain are the fist element in our processing order. The gain can also be set using our Auto Gain
Auto Gain
To use Auto Gain, click the Auto Gain button. A modal opens. Here, click Start Measuring. Speak loud an clear into your microphone for 5 seconds until measurement is finished. If the microphone is clipping, measurement might take a bit longer.
If there is no volume at all detected, measurement will fail. Try enabling phantom power (48V) and increase the gain a bit manually and try again.
AGC
AGC (automatic gain control) dynamically adjusts digital gain of an audio signal to maintain a consistent output level, compensating for variations in input volume.
SubSonic / High-Pass Filter
SubSonic filter, also known as High-Pass Filter, removes low-frequency from an audio signal to remove noise and improves overall sound clarity.
Expander
Expander plugin increases the dynamic range of an audio signal by attenuating the quieter parts and allowing the louder parts to pass through unchanged, making the quiet sounds quieter and enhancing the contrast between soft and loud sounds. Can also be used to reduce noise just like a noise gate.
Variable Filter (Var Filter)
Variable Filter can be used as a variable high pass or low pass to filter unwanted noise.
Equalizer (EQ)
EQ (equalizer) adjusts the balance of different frequency components in an audio signal, enhancing or reducing specific frequency ranges to shape the overall sound.
Compressor
Compressor reduces the dynamic range of a signal by attenuating the louder signals and boosting the quieter ones, thereby creating a more balanced and consistent output.
Limiter
Limiter prevents an audio signal from exceeding a specified threshold by attenuating the peaks, ensuring the output stays within a defined maximum level.
Panorama / Balance
Panorama (or balance for stereo sources) controls the spatial positioning of an audio signal within the stereo field, allowing the sound to be panned left, right, or centered, thereby influencing the perceived direction and placement of the sound source.
Automix
Automix automatically balances the levels of multiple audio channels in real-time, ensuring a smooth and consistent mix without manual intervention. Also reduced unwanted noise by unused channels.
Automix Global Settings
Automix also features settings which influence how the plugin balances audio between different channels. To acces them, open the Global modal.
