QSC Pro Audio CB10

QSC CB10 is a portable, battery-powered active speaker with a 440W Class D amplifier, a 10” woofer, and a 1” compression tweeter. It covers a frequency range from (-6dB) 47Hz to 20kHz for a maximum of 127 dBSPL at 1m distance. It features 2 XLR/¼” combo inputs that accept line or microphone signals, a 3.5mm stereo mini-jack input, and an XLR Mix Out. Bluetooth 5.1 connectivity allows for remote control and audio streaming with a True Wireless Stereo option to link multiple speakers. Operating presets can be selected directly from the rear panel, while more advanced DSP functions are all remotely controllable via the QSC (iOS and Android) Loudspeaker Control app.
Powerful, versatile, and portable
The QSC CB10 has been designed for maximum portability and ease of use, without sacrificing performance. Its battery provides up to 12 hours of operation and takes 4 hours to fully recharge. It is equipped with an IEC connection port for connecting to mains power and recharging the battery.
On the bottom, there is a socket that allows it to be placed on a standard-sized speaker stand. Its 30° tilt angle also makes it perfect for floor placement as a monitor, or for resting on a DJ console for use as a cue speaker, for close and more precise monitoring.
Integrated 3-channel mixer
Its mixer offers 2 XLR/¼” combo inputs, both accepting line or microphone signals.
For channel A, we have 6 presets available, selectable with a 6-position switch located on the rear panel.
List of presets:
'Custom (app)' - allows us to recall a customizable preset via the Loudspeaker Control App
Default
Dance
Speech
Speech (ducker) which will automatically reduce the volumes of other inputs inversely proportional to the amount of signal it receives.
Input B features the same presets, except that Speech (ducker) is replaced by an acoustic guitar preset. Both of these inputs have independent input volume controls, a mic boost, and an LED that indicates signal presence, or potential clipping via green or red colors.
Channel C can receive both Bluetooth 5.1 and analog signals thanks to the stereo Mini-Jack. There is also a TS jack for connecting a footswitch pedal, to which one of the following functions can be assigned via the app:
- Mute per channel
- FX Mute
- Channel Boost
The stylus battery icon found on the same panel shows the remaining charge level of our device in real-time. As for the output, this is also customizable via the App; by default, we find a sum of the signals from the three channels output on XLR with adjustable volume.
Loudspeaker Control App
Via the app, we can control:
- Input volumes of all channels
- Presets for channels A and B
- Equalization for all three channels.
- Reverb for channels A and B
- Ducker for channel A
- Contour selection
- We can choose a custom routing for the physical XLR output
