    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 overrides the Mic input, so if you want to hear something plugged in to the xlr socket, make sure nothing is plugged into the Line input.
  • Page 15 MONO INPUT CHANNEL HF EQ The HF (High Frequency) equaliser affects the frequency response 20 30 of the higher audible frequencies. The corner frequency of 12kHz is GAIN around 3dB from the maximum cut or boost of the circuit. It has plenty of gain and actually gives slightly more that the +/-15dB leg- end suggests.
  • Page 16 MONO INPUT CHANNEL This control sends a signal to an auxiliary bus. The signal is sourced pre-fade or post-fade depending on the PRE switch position. The pre-fade source selection will be affected by the channel ON/OFF switch if active. The send control varies the signal level to the bus from off (fully attenuated) to +6dB, with unity gain at the arrow.

  • Page 18 TELCO CHANNELS TALK The TALK switch enables the presenter or operator to communicate with the telephone caller with the presenters channel fader down so the pre- senters 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-14, the factory default is mono channel 1.
  • Page 19 TELCO CHANNELS AUDITION Switch Pressing the audition button illuminates the red LED and switches the sig- nal from the program bus to the audition bus. The signal is post fade and follows the PAN control. The AUD switch is after the MIX B switch in the signal chain and so has no effect on the MIX B selection.

    SERVICE OPTIONS CAUTION These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock do not perform any servicing other than that contained in the oper- ating instructions unless you are qualified to do so. CAUTION The XB-14 mixer has a versatile architecture which should satisfy most applications that you may encounter without modification.
  • Page 37 SERVICE OPTIONS AUX Pre ON switch / Pre fade option (Mono, Telco and stereo Cut and solder option channels) This is a cut and solder link that sets the action of the AUX pre switch when it is in the down position. The default setting is prefade which sources the audio signal after the ON switch but before the channel fader.
