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 manufactured alongside a wide range of professional audio mixing consoles.
INTRODUCTION TO THE XB-10 USB Getting audio to and from a computer easily is now a common requirement for sound and music production and broadcast applications. 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. dBr 20.00 15.00 10.00 5.00 0.00 -5.00 -10.00 HF -15.00 -20.00 10.00 Hz -15 500 650 +15 1k 200 f 2k 3k MID 120 4k 100.00 1000.00 10000.00 30000.
MONO INPUT CHANNEL AUX This control sends a signal to the auxiliary bus. The signal is sourced prefade (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. PAN The pan control adjusts how the signal from the mono input channel is shared between the left and right sides of the PGM bus.
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. (See next page for more information about the cleanfeed output). TELCO Input Gain The Telephone Communication channel input gain control.
TELCO CHANNEL TALK The TALK switch enables the presenter or operator to communicate with the telephone 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. The signal source is prefade and pre-mute on the selected mono channel.
TELCO CHANNEL TALK CLF SCE PGM AUX 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. AUX 0 +6 PRE PAN L -20 R -10 LEV -30 0 PK ! PFL SIG T1 L ON Switch This mechanically latching switch operates the channel mute circuitry, turning the signal to the PGM, ALT and Aux buses on or off. With the button depressed the signal is routed to the PGM bus and the pre/post AUX bus.
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. L R Stereo Channel Inputs L Standard 1/4” jack sockets for input signals to ST1 - 3. Wired Tip=Hot(+), Ring=cold (-), Sleeve=Chassis. Impedance balanced.
STEREO INPUT CHANNELS BAL 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. Level This control adjusts the level of the channel signal to the left & right PGM bus, ALT bus and post fade Aux.
OUTPUTS GROUND CANCEL SELECTORS Both the MON OUT and RECORD OUT connectors are ground cancelled. The signal ground is lifted with a 75ohm impedance 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. RECORD OUT This is the PGM mix but taken before the main output level pot. Standard RCA phono sockets. Ground cancelled output. Nominal level = 0dBu.
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. If the CLF-TELCO button is pressed then then left channel will send the telco channel cleanfeed and the right channel will send the TELCO channel signal.
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 activates 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. The limiter LED will come on as soon as the limiter reaches its threshold.
MASTER SECTION Main Left & Right meters 12 segment LED meters, peak type response, the “0” position reflects nominal level at the outputs (+4dBu from the main PGM outputs). The meters display the signals from the Operator phones selector switches below, or the PFL (pre-fade listen) signal from any selected channels, which overrides. MAIN PROG LEVEL -10 -30 L 0 These 5 switches select the signal source for the monitor speakers, operator phones and the meters. They work on a signal mix basis.

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. Do this by monitoring the telco channel with the PFL button. Pressing the telco channel talk button will allow the caller to hear the presenter.
