QED SWITCHING FAQ

What are the differences between the speaker switches in terms of impedance?

All the speaker switches are configured so that if you use 8 Ω speakers the minimum impedance seen by the amplifier will be 4 Ω

 

What are the benefits of series vs parallel ?

The switches which have more than two sets of speakers use a combination of series and parallel switching to achieve the minimum impedance of 4 Ω no matter what combination of speakers are switched on. For the two way switches there is a choice between exclusively series or parallel versions. If you have 8 Ω speakers (and a 4 Ω min amp) you should always use the parallel switch. If you have 4 Ω speakers and a 4 Ω min amp you should always use the series switch.

 

All QED switches load on 4 Ω using 8 Ω speakers. What happens if my speakers are 6 Ω?

1. Check your amp – if it can cope with a 3 Ω load or less (and some can) then you are alright. The rule is you must always use speakers with double the impedance of the amp minimum. 2. If you only have two pairs of speakers then use the two way SERIES switch.

 

How do the switches deal with power, e.g. if I have an amplifier with more than 150 watts?

These accessories use mains switches which are rated at 6A which means the max power they can handle is 288W given an 8 Ω load

If my amp is rated 6-16 Ω should I really be running a 4 Ω load?

NO, NEVER – you should use 12 Ω minimum speakers. You can get 16 Ω speakers though – but it may just be easier to change the amp.

 

Can I use them in reverse e.g. as an amplifier switcher (we know the answer is no, but why?)

NO – because the speaker switches are designed to have two sets or more of speakers attached to one amp, if used in reverse there is always the possibility of connecting two amps at once to one pair of speakers resulting in damage to one or both amps.

 

What is the technical definition of 'transmatch'?

For the 5 way speaker switch we don’t use parallel or series switching but use transformer coupling instead. Again you have to use 8 Ω speakers minimum if your amp is a 4 Ω minimum amp. The impedance is then matched by the transformer (hence the name) so that a net 1.6 Ω load (all 5 sets of 8 Ω speakers switched on)is converted back to a 4 Ω load. One pair of speakers (A) is not connected to the transformer but is directly connected to the amp, these will be the main speakers. The four B pairs are connected via the transformer.

QED
QED wurde 1973 von Abraham und Ian Vine gegründet. Ihr Ziel war es damals schon einen neuen Blick auf die Möglichkeiten der Qualitäten eines Hifi-Kabels zu legen.
Das QED 79 war somit nicht ein weiteres Lautsprecherkabel auf dem Markt, sondern ein ernsthafter Fortschritt bei der Entwicklung neuer Maßstäbe eines Kabels. 1994 führte QED weitere umfangreiche, wissenschaftliche Untersuchungen durch, um das genaue Zwischenspiel zwischen dem Hifi-Kabel und einem weiteren Hifi-Komponenten nachvollziehen zu können.
QED ist heute für innovative Ideen und technische Exzellenz auf der ganzen Welt bekannt. Das Forschungs- und Entwicklungsteam von QED ist stets bemüht Schritt mit dem technischen Fortschritt zu halten und dabei dem Kunden eine Zuverlässigkeit der Produkte zu garantieren.
Ebenso legt das Unternehmen auch viel Wert auf ein faires Preis-/Leistungsverhältnis, um besonders vielen Menschen den Musikgenuss mit hochwertigen Kabeln zu ermöglichen.
