INTRODUCTION TO THE XB-10 Background overview The Allen & Heath XB-10 mixer has been carefully and lovingly designed in the beautiful county of Cornwall in the UK and is manufac- tured alongside a wide range of professional audio mixing consoles. Many of the components used in the XB-10 are exactly the same as in the larger Allen &...
INTRODUCTION TO THE XB-10 Getting audio to and from a computer easily is now a common requirement for sound and music production and broadcast applica- tions. The way we have implemented this on XB-10 is super-flexible and super-easy! No longer do you need to fiddle around the back of your computer to get to the soundcard inputs, only to find that the levels are all wrong and noisy.

MONO INPUT CHANNEL Mic Input Socket Standard 3-Pin XLR socket wired as Pin 1=Chassis, Pin 2=hot (+), Pin 3=Cold (-). Line Input Jack Socket Standard 1/4” (6.25mm) Jack socket for balanced or unbalanced line level signals. Wired Tip=Hot(+), Ring=cold (-), Sleeve=Chassis. The Line input connects to the XLR input via a pad, so be aware that the two signals will add together if both inputs are plugged in simultaneously.

MONO INPUT CHANNEL HF EQ The HF (High Frequency) equaliser affects the frequency response of the higher audible frequencies. The corner frequency of 12kHz is around 3dB from the maximum cut or boost of the circuit. It has plenty of gain and actually gives slightly more that the +/-15dB legend suggests.
MONO INPUT CHANNEL This control sends a signal to the auxiliary bus. The signal is sourced pre- fade (and pre ON switch) or post-fade (and post ON switch) depending on the PRE switch position. The send control varies the signal level to the bus from off (fully attenuated) to +6dB, with unity gain at the arrow.
TELCO CHANNEL TELCO IN The Telephone Communication channel input 1/4” (6.25mm) Jack socket . Wired as Tip=Hot (+), Ring=cold (-), Sleeve=Chassis. CLF OUT Standard 1/4” (6.25mm) Jack socket for the Clean-Feed output from the Telephone Communication channel. Wired Tip=Hot (+), Ring=cold (-), Sleeve=Chassis. Impedance balanced. Nominal level = 0dBu.

TELCO CHANNEL TALK The TALK switch enables the presenter or operator to communicate with the tele- phone caller with the presenters channel fader down so the presenters voice does not go to the program mix. The source for the TALK signal is one of the mono channels, pre-selected by links set within the XB-10, the factory default is mono channel 1.

TELCO CHANNEL TALK CLF SCE Level This control adjusts the level of the channel signal to the left & right PGM bus, ALT bus and post fade Aux. With the pot fully clockwise, the channel has unity gain. ON Switch This mechanically latching switch operates the channel mute circuitry, turning the signal to the PGM, ALT and Aux buses on or off.
STEREO INPUT CHANNELS Monitor input / USB input The monitor input is on standard RCA phono sockets and is commoned with the ST1 inputs. This means that the monitor input will appear on the ST1 channel if nothing is plugged in on the 1/4" channel jacks. The USB input channel is commoned with the ST3 channel and works in the same manner.
Page 22
STEREO INPUT CHANNELS The balance control adjusts the relative levels of the left & right signals in the stereo input channel as they are sent to the PGM bus. Set to the mid position, the signals are balanced equally. With the balance control set fully anticlockwise the right channel will be fully attenuated and the left channel will increase by approximately 3dB.
OUTPUTS GROUND CANCEL SELECTORS Both the MON OUT and RECORD OUT connectors are ground cancelled. The signal ground is lifted with a 75ohm im- pedance to eliminate issues with hum and earth loops. To disable this function and allow a direct earth connection, depress the rear switches with a matchstick or similar.
OUTPUT SELECTOR USB OUT SOURCE The signal source for the USB send is selected using the switches below the USB connector. If both switches are un-pressed, the pre level main program mix will be sent to the USB output, if the AUX-ALT button is pressed then the AUX and ALT mixes will be sent to the left and right channels respectively.
MASTER SECTION Output Limiter The limiter controls are on the rear panel of the XB-10. Use a matchstick or similar to press both mode switches, this acti- vates the limiter for the left and right channels respectively. The trimmer pot can be adjusted with a small bladed screwdriver and this allows the limiter threshold range to be changed from 0dBu to 21dBu.

APPLICATION TIPS: VOIP CALLER ON TELCO CHANNEL This diagram shows the basic mixer setup for a conversation with a Skype/ VOIP caller. Ensure the buttons marked with a star are pressed to route the telco channel and cleanfeed to the computer VOIP program. Before going to air the presenter can speak with the caller.
