Connecting Speakers
When connecting speakers to the CLP1200, ensure that the combined load for each output (left or right) is no
lower than 4 Ohms (4Ω). To make sure of this, check the manufacturer’s information.
If connecting more than one speaker to an output channel, observe the following calculation method.
Note: normally, speakers will be connected in parallel by connecting a speaker lead from on to another.
Most PA and sound reinforcement speakers are 8Ω, so we consider that 1/8 + 1/8 = 1/4.
Therefore, when connecting 2 x 8Ω speakers together in parallel, the resulting total load is 4Ω.
It is also important to ensure that the power delivered to the speakers will not overload them.
The CLP1200 will deliver 600Wrms per channel at 4Ω or 400Wrms per channel at 8Ω.
An 8Ω speaker connected on its own to an output channel must be able to handle at least 400Wrms.
A 4Ω speaker connected on its own to an output channel must be able to handle at least 600Wrms
When connecting 2 x 8Ω speakers to a single output channel, they will share the 600W output equally.
Therefore, it is important that they can handle a minimum of 300Wrms each.
