FREQUENTLY ASKED QUESTIONS

Frequently Asked Questions

How much latency do the speakers have?
In full processing mode, the DSP introduces about 46ms of latency; in low latency mode, less than 3ms.
Is it possible to change modes remotely?
Currently the modes are operated by switches on the plate; we’re working on adding remote control for future models.
Will Ex Machina ever make a subwoofer?
Standalone, likely no.  Our unique phase linearity requires known distances from subwoofer to mid, and mid to tweeter.  As a result, we’ve integrated high excursion, high output subwoofers directly into all our 3-way designs.  Ganymede and Pulsar have more than enough output and extension for stereo nearfield operation without the need for a separate subwoofer, and Quasar and Arcturus have more than enough output and extension to eliminate the need for a separate subwoofer even in most surround setups: simply run them full range, and route the LFE channel to them.
Why is there speckling on the cabinets?
What you’re seeing are the natural fiber variations of the Valchromat material.  These interlocking fibers are part of what make these cabinets so acoustically inert, as they provide both increased stiffness and damping vs standard MDF materials.
If Ex Machina speakers are DSP powered, why are there no digital inputs?
Simply put, AES/EBU input streams are lossy to attenuate; our extremely high quality AD/DA conversion, conversely, leaves no audible footprint.  In the future we may consider adding networked digital control that can directly attenuate the loudspeaker using the floating point processor engine.
Are Ex Machina monitors exclusively sold in pairs?
No, individual units are available for every model except Titan.
The XLR input says “balanced analog input.” How do I connect them to an unbalanced interface/preamp/controller?
Ex Machina monitors are entirely internally balanced, and we therefore do not recommend the use of unbalanced front ends.  If it is necessary to connect our monitors to an unbalanced source, we recommended tying cold to ground on your cables at the source side, but not on the speaker side.  However, we cannot guarantee performance with unbalanced sources.
The manual says “never touch the tweeter” in big red letters. What happens if I touch the tweeter?
If you’re very lucky, nothing.  If you’re not, the diaphragm being extremely thin/light, as it needs to be to achieve its exceptional extension and transient linearity, may be crushed or punctured.  This sort of damage is not repairable, and will require a replacement driver, which is not covered under warranty.  Sketchy online tutorials suggesting crushed tweeters can simply be pulled back out with tape are spurious, and certainly do not apply to carbon composites.

Troubleshooting

Speakers are not outputting sound
Check your wiring connections and power connections at the loudspeaker.  Make sure to give the loudspeaker DSPs approximately 45 seconds to boot up after initial power up before running signal into them.  When powering down the loudspeaker, wait at least 1 minute before powering them on again, so that the flash memory has time to purge.  Failure to do so may cause startup sequence errors.
Phasing/Time Delay/Sound is coming from “outside” the speakers
Check the polarity of your XLR cables and the polarity of your source.  Make sure both speakers are in the same processing mode; if one is in full cal, and the other low latency, there will be a noticeable time delay between the two.
Hum/Buzz issues
Make sure that you’re using a balanced, properly grounded source for the loudspeakers.  If problems persist, try the following solutions.

  1. Especially when using USB bus powered interfaces, make sure that the computer powering the interface and the speakers are plugged into the same power strip on the same outlet, and make sure that the computer is using a properly earth referenced, 3 prong power cable.
  2. Try lifting the shield from Pin1 at the speaker side of the connection, but not the source side.
  3. Make sure your XLR cables are as short as possible, and do not use a drain wire.
