Audio590 is a Windows program that lets you set up and manage audio profiles for use with a TS-590SG or TS-590S transceiver. You can read existing audio settings from the radio, display them on the control panel, change them and then write them back to the radio. You can also save the settings on disk, and retrieve them later when you need them.
Audio590 helps you configure any kind of audio source for transmission. For example, you can define a different profile for every mic you have, or different profiles for people sharing the same mic in a multi-operator contest, or a complete set of individual profiles for all your digital applications.
Above all, Audio590 saves you the hassle of making copious notes on audio TX/RX level settings, VOX settings, audio processor settings, TX and RX equalizer settings and so forth, for every different kind of audio you use. All of these settings are saved in Audio590, and when you want to try a different mic, or switch to a different digital program, you can instantly retrieve the correct settings.
Audio590 is “bilingual”: it works with both the TS-590SG and the TS-590S.
Audio590 is a compact stand-alone program (around 135 kB) that runs under any version of Windows XP, Windows 7 and Windows 8. The program handles the management of audio and audio-related information for USB and LSB transmission and reception (later versions will support AM and FM as well). The program does not support CW or FSK modes.
The term “audio” has a wide meaning. It includes the conventional voice modes, plus any digital modes that send and receive AFSK signals; for example, RTTY (AFSK), PSK31, Olivia, WSJT-X, SSTV, digital voice (DV) and many more – even MCW.
AUDIO590 IN ACTION
This picture shows the main functions of Audio590:
After you CONNECT the Audio590 program to the TS-590 (either through the radio’s RS.232 COM port or the USB Virtual COM Port), you can READ the radio’s current settings. The settings are then displayed on the Audio590 Control Panel.
At this point you can accept the downloaded settings as they stand, or modify them on the Control Panel if you wish. At any time you can WRITE the settings back to the TS-590, to ensure they are the same as in Audio590.
Finally, you can SAVE the settings in the Audio590 Repository on disk for future use. Thereafter you can LOAD the settings back into Audio590, in preparation for writing them back to the radio.
EXAMPLES OF AUDIO PROFILES
Here are some examples of how you might set up audio profiles.
You may have a collection of different microphones, each with its own characteristics:
The yellow boxes show some of the relevant audio profile parameters. In this example, the headset is connected to a PC, which feeds the audio to the radio’s USB port, the desk mic uses the radio’s MIC socket, and the studio mic uses the radio’s ACC2 port.
For each of these mics, the audio gain level, audio processor, Lo/Hi Cut filters, TX equalizer and other settings will be different. Some of these settings will be made on the TS-590 front panel, others through menus.
Clearly, if you have several mics, each requiring its own audio profile, the number of adjustments you need to make each time you swap to a different mic rapidly becomes unmanageable.
Different profiles for the same mic
Even if you only have one mic, it’s possible to set up several audio profiles:
You could set up one profile for laid-back roundtable chats. Here, since the mic is positioned some distance from the mouth, the mic gain is quite high, VOX is turned on, and the audio processor is turned off.
The situation is quite different when you are chasing rare DX. Now you are almost eating the mic (so you need much lower audio gain), VOX is turned off, PTT is through a footswitch, and the processor is turned on. Also, because you are much nearer to the mic, you need to reduce the low frequency response by
increasing the LoCut frequency, and you need to switch to TX equalizer HB2 to further emphasize the higher frequencies.
Multiple operators sharing the same mic
In a multi-operator contest you could have several people sharing the same mic:
The operators’ voices are quite different:
*** Herby’s voice is “average”, so the appropriate mic gain level is in the middle of the range, and the HB1 TX equalizer is the best for him.
*** Nancy is softly spoken, so she needs a higher mic gain, and also needs a user-defined equalizer (U) to compensate for her high-pitched voice.
*** Archie bellows unbelievably, so the appropriate settings for him are different again!
With a separate audio profile for each person, you can quickly change the setup whenever one operator hands the mic over to another.
If you are interested in digital transmission, the number of audio profiles could escalate to a dozen or more:
For example, if you are running Fldigi, you may decide that each mode requires a different profile:
*** PSK31 is essentially a low power mode, so you could set the TX power to 5 watts.
*** When transmitting RTTY you will probably want to run 100 watts.
Also, for most digital modes you will undoubtedly wish to select USB, and turn PROC off (to avoid distortion). You may require yet further audio profiles if you run SSTV or digital voice.
AUDIO590 SAVES ALL THE CONTROLS YOU NEED IN INDIVIDUAL AUDIO PROFILES
Some of Audio590’s functionality is similar to ARCP-590, but Audio590 goes further. In particular:
*** Audio590 saves all the required settings. (ARCP-590 does not save 14 front-panel settings that are crucial to audio transmission and reception, including DATA on/off, PROC on/off, audio processor settings, MIC gain, MIC VOX gain/delay and others). These 14 controls are ringed in red here:
*** Audio590 lets you save any number of U equalizers, with meaningful names. (ARCP-590 only lets you save five user-defined equalizers, with unhelpful names like User1, User2 etc.).
*** Audio590 lets you save User-defined equalizers that are based on the standard built-in equalizers (HB1, HB2 etc). This saves time if you only want to make a small change to a built-in. (ARCP-590 does not save modified built-in equalizer settings).
*** Audio590 lets you display the TX and RX passband of any equalizer, showing graphically the effects of the TX and RX audio cut-off settings. (ARCP-590 does not have this functionality).
In Audio590, the passbands are color-coded: RED = Built-in TX Equalizer, GREEN = Built-in RX Equalizer, YELLOW = User-defined TX Equalizer, and CYAN = User-defined RX Equalizer:
On the passband displays the thin red lines show the effects of changing the audio filter settings (HiCut/LoCut and Shift/Width).
