If you are plugging your headphone output of your phone or MP3 player directly into a mono input on your mixer, audio interface or active speaker by using a TRS adapter or cable, then you may notice the audio does not sound correct. You may hear loss of vocals, weaker bass or bad levels of distortion. This is a phasing issue - a result of supplying your mono input with a stereo signal. In this video, we explain that such problems can easily be avoided using a specific cable type in conjunction with two mono input channels. The cable type you would need is a '3.5mm TRS to 2x 6.35mm TS’ stereo breakout cable.
This video will offer you a thorough connection guide for using your S16 stagebox with X32:
You can quickly adhere to the following to allow the S16 and X32 to communicate with one another:
1. Connect a shielded Cat5e cable to the AES50A port of the X32 and the AES50A port of the S16.
2. Press and hold the CONFIG button of the S16
3. With the CONFIG button held, rotate the HA encoder knob counter-clockwise until the display reads "1-8" and no LEDs are lit on the right-hnad side of the display.
4. On the X32, navigate to the CONFIG tab of the SETUP screen.
5. Set the Synchronization to LOCAL.
This setup will allow the S16 and X32 to communicate with one another to send signal back and forth between the two devices.
If you are using a valve amplifier, then you may encounter a small popping noise when you switch from channel to channel. This type of noise tends to occur in all valve amps that use feedback loops to attain high levels of gain. The popping noises that you hear are often unavoidable when feedback loops are engaged for high gain channels. Simply, this is the nature of the beast.
Keep in mind that when you use a valve amp, it’s good practise to warm up your valves before playing. Your valves will play at optimal performance in this state. When warmed up, the chances of hearing any popping will decrease. Your valves can take up to a few hours to reach optimal temperature – as is the case with all valve amplifiers. The key takeaway is to keep your amps on before performances and during intervals; your valves will be warm before you begin playing.
Most valve amps feature a ‘standby’ switch. These can be used to silence the amp and keep valves heated when not in use.
The ideal drive unit is one that can reproduce the entire audio spectrum, from the lowest bass notes to the highest treble. Unfortunately, such a device does not exist, as the physical demands of the two are very different. Multiple drive units are therefore accepted as a compromise, with the bass and treble parts of the signal being reproduced from different places.
The benefit of having the high frequency drive unit in the centre of the low frequency one is that the whole audio range is perceived as coming from the same point in space, like the ideal drive unit.
With Dual Concentric, both sources come from the same coincident time aligned point in space, and this phase coherence leads to constant directivity through the crossover region, producing an even off axis frequency response.
