The 8c speaker system has one input that can be used for either AES3 digital audio or for an analogue signal. There are several parameters that can be adjusted to achieve the best signal to noise ratio for your setup.

Verifying the output level of your source

First of all you need to identify if your source or mixing desk has a +4dBu (professional) output or a -10dBV (consumer) output. You can verify this using the manual of your audio source or mixing desk. Once you have verified this you can select the matching input level of the 8c system using the button at the back or the app.

General gain settings in

As a default the gain of every 8c speaker system is set to 0dB. In normal conditions you do not need to increase or decrease this level. You can however decrease the gain setting to get a better signal to noise ratio. This is only possible if your source can output sufficiently loud or when a lower output level of the 8c system is acceptable. You can also increase the gain setting to above 0dB. This is only needed if your source cannot output at sufficiently high levels in order to reach extreme audio volume. Please note that increasing the gain above 0dB will affect signal to noise levels

Analog signal with a professional setup

If you have a professional mixing desk or D/A converter you need to select the +4dBu input of the 8c speaker system. This will now match the output of your desk or converter. Please check the manual of your desk or converter to ensure that this equipment also outputs at +4dBu. In the app you can also set the gain setting per speaker. The default should be 0dB since this now also matches the gain of your desk or converter.

Analog signal with a consumer setup

Consumer equipment output audio signals at a lower level than professional equipment. To make sure your 8c speaker system can play sufficiently loud you need to select the -10dBV input. In the app you can also set the gain setting per speaker. The default should be 0dB in order to match the output levels of your source to the input gain of the -10dBV input.

AES signals

You can use the input of the 8c speaker to play a digital AES3 signal from your source. The 8c accepts a maximum frequency of 192kHz. Also, you can use the thru XLR chassis connector output to daisy chain the first 8c speaker to the second 8c speaker. Every set of 8c speakers is shipped with an XLR terminator. You need to plug this connector in the thru chassis connector output of the second 8c.

You can select the required input mode using the small button at the back of each 8c or using the app. You can select if each 8c uses the left signal or the right signal from the AES3 stream. You can also select both. In this case the left and right signal will be summed and you will listen to a mono signal from that 8c speaker. Please note that the 8c does not accept a coded multichannel (surround) audio feed.
