The Allen & Heath XB-14 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. Many of the components used in the XB-14 are exactly the same as in the larger Allen & Heath products and the construction methods are also very similar — utilising individual vertically mounted channel circuit boards with each rotary control fixed with a metal nut to the front panel. This provides a very robust product that will resist damage and give years of reliable use. It also makes servicing much easier should it be required, with the ability to remove one particular channel from the mixer at a time, or easily change a fader. The audio circuitry is based on years of continual development and refinement , the performance of all the elements within the mixer scrutinised and perfected to ensure the very best sound quality possible. Multi-application: The XB-14 is great for a range of applications from small radio or internet broadcast studios, or for larger studios with multiple rooms, for hospital radio, university radio and community radio broadcast applications. The XB-14 has a wealth of features specifically designed for broadcasters, things like telephone communication modules for telephone callers, mic fader start sensing for external connection and internal automatic muting of the speaker outputs, stereo channel start/cue outputs for CD deck transport control, separate headphones mix & outputs for guests, an audition bus…. The list goes on! Mic/Line Pre-amps: The XB-14 pre-amps use a two stage design, with carefully controlled amounts of gain in each stage. When amplifying the signal from the XLR input, the gain range is huge (69dB of range to be exact) and is very evenly distributed around the gain control, meaning better control of signal level. Most of the gain comes from the first stage, so unwanted noise is kept to a minimum. There is no “pad” switch, or pad circuit — line level signals are simply plugged into the second stage of the pre-amp by using the line input jack socket. This has the great advantage of lower noise when using the line input. (It is common to attenuate line level signals, then amplify them back up again which can give more noise or hiss). EQ: The XB-14 is equipped with a 3-band equaliser circuit on each mono input and a 2-band EQ on the Telco & stereo channels. The frequency and response of each has been carefully chosen to give the maximum performance when using the EQ on a variety of sources. AUX bus: XB-14 has a single Auxiliary bus that can be used for external processing, effects, recording or auditioning. MIX B: A separate stereo mix bus is provided for recording an independent mix to the main program mix, or creating a clean feed source with selected channels. Remote Control: The mono mic/line channels have fader start logic switching enabling them to control external equipment or automatically mute the speaker outputs to prevent acoustic feedback in localised or self-operated applications. The stereo channels have start & cue logic outputs available to hook up to external equipment like CD players. There are also options to mute the mono inputs remotely using an external “cough” switch or similar. 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-14 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. Just plug in a USB lead to your XB-14, select the USB routing on the mixer and the device on your computer and that’s it! Quality audio to and from your PC or MAC. Self operation or Producer operated: Whether you need a mixer for a self operated broadcast situation, or whether you have a separate studio and engineer, the XB-14 has the features to fit. Separate monitor mixes can be created for operator and guests or presenter so the engineer can check levels and cue sources while the presenter or guest can listen to a different source. The engineer/producer can communicate to the guest or presenter using the Talk feature, as well as off-air communication to telephone callers. There is also the facility for remote control of channel mutes from the studio using the remote interface connectors, ideal for studio situated mute switches.

In addition, the AUX bus can be used for off-air audition or recording of an interview with a telephone caller (or callers), using pre-fade signals to the AUX bus for later playback or editing for the broadcast. By pressing the CLF SCE switch the caller will hear the audition mix, or the off-air record mix without their own voice. 10 L The Clean-Feed Source switch selects the signal source for the TELCO output. In the un-pressed position the signal will be the entire program (PGM) mix (pre main PGM fader) but without the signal from the input on that TELCO channel, so the caller does not hear any distracting echo of their voice.

Dynamic microphones won’t mind being connected to a phantom powered input, but care is needed to ensure that 48v is not switched on if an xlr is used to input a signal from an electronic circuit (ie. Another mixer or keyboard). When switching 48v on or off, or plugging in connectors to channels with 48v present, it is important (and normal procedure) to mute the channels. This will avoid loud clicks and bangs potentially getting through to the amps & speakers with the possible effect of damaging the speakers, or the audience’s hearing! These 4 switches select the signal source for the control room speakers, headphones monitor and the meters. They work on a priority basis. If they are all up then the post-fade main PGM signals will feed the monitor circuit, if any of the switches are pressed then the PGM signal will be replaced. If more than one switch is pressed the switch nearest the meters will take priority. The PFL signal will override the selection to the meters and CRM if activated. Similar to the CRM + PHONES selection switches, these select the source for the guest headphones output. The choices are the same as for the CRM outputs, but a different source can be selected for the guests to that selected for the operator. The PFL signal will not be fed to the guest phones outputs unless the PFL ENABLE TO GUEST switch is pressed. This is an under-panel switch so it cannot be operated accidentally.

The logic signals are usually wired to a 2 pole 3.5mm jack plug where a low pulse on the tip starts the deck and a low pulse on the sleeve stops or cues the deck. There needs to be some form of ground connection between the equipment for this to work—normally effected by the audio connector leads. Notice that there are Start/Cue outputs for 7 machines even though there are only 4 Stereo channel ON switches. That’s because there are dual inputs on 3 of the stereo channels making a total of 7 sources and the XB-14 only sends a Start/Cue signal to the deck selected as a source to the channel whose switch is pressed. It’s clever like that!

In the up position, the channel ON switch will act as a normal ON/OFF switch affecting the channel signal accordingly. If the slide switch is moved down to the “ON” position, then the corresponding channel’s ON switch will be disabled (made so that it is jammed ON). The green LEDs in the switch will then permanently illuminate. UNLESS…. Unless you are using the Stereo channel ON switches for transport Start/Cue and would like the channel mute circuit disabled but the switch illumination still to follow the switch position. In this case use the last switch in the row to disable the mute circuit on all 4 stereo channels, but make the illumination follow the switch position. If you want, you can disable the Stereo channel mute circuit on an individual channel basis using the Stereo Inputs 1,2,3 & 4 slide switches individually. This will make the channel permanently on and the switch illumination also permanently on. This may seem like a fussy complication, but could be useful if you want to revert to basic operation, where only the faders control the signal going out on air, disabling the ON switches so the operator cannot turn off the channel accidentally, but still want the switch illumination on certain stereo channels to follow the Start/Cue on the CD player or deck.

It is fully compliant with USB 2 ports and uses standard Windows and MAC Core Audio Drivers. In other words, plug it in and your computer will find it and be able to transfer audio to and from the XB-14 USB device. You will need some form of audio software running on your computer to be able to record and play back what you record, but on a basic level, you can use your computers media player to play straight to the XB-14 device. Just a couple of points to look out for: 1. When you plug in your XB-14 USB interface to your Windows computer, check the device volume in: Control Panel\Sounds & Audio Devices\Volume If the volume is not fully up like this…... Then drag it fully up like this…... Then click Apply 2. By default Windows will use its WDM driver for the data stream from the USB audio device.
