The SS20 way parallel speaker switch by QED allows you to switch between two pairs of speakers (in parallel) for total flexibility and control. if you need to use your amplifier on full power for a louder sound delivery, you can simply switch on your second pair of speakers for that extra wow factor.
When you wire your speakers in parallel, this means you will deliver more power to each speaker. This is due to the equivalent resistance of the circuit being less than that of the individual speakers. For perfect set up and to avoid damage to your amplifier, you should always calculate the combined impedance of the speakers that you will be wiring and connecting in parallel. You will need to check that the combined impedance is not below the minimum impedance requirements of your amplifier. For example, if you have two 8 ohm speakers this would create an equivalent resistance of 4 ohms if wired in parallel.
**If you have 8 Ω speakers (and a 4 Ω min amp) you should always use the parallel switch.
The main features and benefits of the QED SS20 2 way parallel speaker switch include:
- Minimum Load Impedance – 4 Ω (Using Two Pairs Of 8 Ω Speakers)
- Power Rating: 150 WATTS RMS
- Silver Plated Switch Contacts
- Large Cable Entry Protected Terminals (3.95MM DIA)
- Dimensions (HXWXD): 55MM X 157MM X 155MM
- Suitable For Use With WM14 Wall Mounted Volume Control
