QED SWITCHING FAQ
What are the differences between Speaker Switches in terms of Impedance ?
All the speaker switches are configured so that if you use 8 Ohm speakers the minimum impedance seen by the amplifier will be 4 Ohms
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 ohms 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 ohm speakers (and a 4 ohm min amp) you should always use the parallel switch. If you have 4 ohm speakers and a 4 ohm min amp you should always use the series switch.
All QED switches load on 4OHMS using 8OHMS speakers, what if you speakers are 6OHMS?
1. Check your amp – if it can cope with a 3 ohm 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 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 ohm load
If my amp is rated 6-16OHMS should I really be running a 4OHMS load?
NO, NEVER – you should use 12 ohm minimum speakers. You can get 16 ohm speakers though – but it may just be easier to change the amp.
Can I use them in reverse e.eg. As an amplifier switch.
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.
