Device configurations allow you to fine-tune the input combinations (audio/video/display) a device accepts and the quality of the input the device captures. After you establish your preferred device configurations, specify them when you add or edit the individual device.
You could create a few different configurations and apply them to different devices. You might, for example, create a device configuration that captures audio, video, and VGA at the highest qualities possible, then apply it to the EchoSystem SafeCapture HD in the premier lecture hall. Another device configuration could apply to the Classroom Capture device in a classroom primarily used for seminars and discussions.
After you establish a device configuration, edit it only when absolutely necessary. If you are not satisfied with the capture quality, optimize the equipment in the venue first. Adjust the camera, the audio device, or the lighting first, review some Echoes, then adjust again. The environment in the venue affects the capture quality. If one Instructor turns on every light, the Echo may look washed out. If another Instructor turns off every light, the Echo may look dark. Adjusting the device configuration would not solve issues caused by a changing venue environment. |
Please be aware that when adding or editing a Device Configuration for the Echo360 PRO, you will need to configure the One-Touch Product Group. The One-Touch Product Group is the input configuration used by default whenever a user presses the Record button on the front of the Echo360 PRO. This configuration should be set in order to make full use of the Record button.
Before you adjust the gain on a capture appliance, adjust the gain on all of the other sound equipment in the venue. When the sound quality of other equipment is stable, adjust the gain on the capture appliance. This way, the sound quality you hear when you adjust the capture appliance is sure to be the sound quality you hear on recordings. |
Pink noise, which sounds like static between FM channels, has a very low crest ratio and low dynamic range. The sound has a fairly constant power level, so the overall power level is higher than normal speech. This should get you a good starting point for further fine-tuning of audio.
Connector Type | Level | Range |
---|---|---|
RCA Audio Connector | Consumer | (-10dBv / 0.316Vrms / 0.447Vpk) |
Bare Wire Audio Connector | Professional | (+4dBu / 1.228Vrms / 1.737Vpk) |
If you are configuring the SafeCapture HD, you can specify that the device capture in widescreen. If you do this, all devices with the configuration will capture in widescreen. This may result in Echoes with black bands on either side of the display area ("curtains"). This figure below shows a test pattern with curtains:
The curtaining effect occurs in this situation:
Once the lecture is captured, the "curtains" cannot be removed, even if the Echo is reprocessed.
Echo360 recommends that you:
You cannot delete a device configuration that is assigned to a device.
