  • Dimensions (HxWxD): 55 mm x 157 mm x 155 mm

The SS30 3-Way Series Speaker Switch allows you to switch between up to three pairs of speakers for your ultimate set up. The SS30 enables safe connection and switching of three pairs of speakers from a stereo amplifier.

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
