The GSX 1200 PRO allows you to regulate your chat volume and that of your teammates. That makes the GSX 1200 PRO more suitable for a professional studio/esport team setup, rather than for the casual gamer.Why am I unable to set my main audio device to 24bit?To be able to set the default format to 24bit 96khz, you must set the device to stereo, not 7.1 Surround Sound. This is due to the USB interface not being able to send out 8 channels of full 24bit audio.Why are two playback devices listed in my playback settings?The Main Audio device has the Surround Sound processing and should be set as your default playback device. The Communication Audio is a separate audio channel and should be your default communication channel. Having both, Main Communication and Main Audio in the same channel would result in surround processed voices which deteriorates communication quality.How does the chat volume wheel work?The chat volume wheels do not work for in-game chat such as in CS:GO. It only works on communication software such as Skype, Discord, and TeamSpeak.Why do I get the error message Format is not supported by this device when configuring the settings and selecting 7.1 Surround Sound?To fix this, you have to set your main audio device to 16Bit.- Go to Playback Devices.- Double-click the GSX 1000/1200 PRO main audio.- Go to the Advanced Tab and then set to 16Bit 44100 Hz and press apply.Why am I unable to hear 7.1 Surround Sound in Windows Media Player (or similar player)?Be aware that Windows Media Player does not natively support 7.1 Surround Sound. You might be able to find a codec that enables it. We have good experience with the K-Lite codec pack but cannot guarantee that it will work for you.EPOS | Sennheiser GSX 1000 Audio Amplifier Specifications:USB StandardUSB 2.0 full speedUSB audio 1.0Total Harmonic Distortion0.005% THD @ -3dBFSCable Length1.2mmConnector Plugs3.5mm headset socket3.5mm microphone socket3.5mm loudspeakerMicro-USB socketCompatibilityPCMacWarranty2 yearsInternationalMain Audio Sample Rate7.1: 44.1kHz @ 16 bit7.1: 48.0kHz @ 16 bit2.0: 44.1kHz @ 16 bit2.0: 48.0kHz @ 16 bitMain Audio HD Sample Rate2.0: 96.0kHz @ 24 bitCommunication Audio Sample Rate1.0: 16.0kHz @ 16 bitAudio Outputs: HeadphonesDC coupled and dual rail power supplyFrequency Response: 0 - 48.0kHzRecommended headphone impedance: 16 - 150Max. output voltage: 1V RMS @ 32Audio Outputs: Line out (AUX)Frequency Response: 1.5Hz - 48.0kHzMax. output voltage: 1V RMS @ 10Dimensions of Product PackagingL x W x H150mm x 70mm x 145mmPackage Weight389gIncludi
