Speaker output loading Chart

This stereo amplifier is designed to operate external speaker systems down to 4 ohms per channel. Use the chart below to determine the total load of different cabinets connected to the two jacks on each channel. Loads shaded gray are not recommended. If two cabinets are daisy chained together and plugged into one speaker jack, you will have twice the load and half the impedance (Ohms) as one cabinet. For example: If two 8 ohm cabinets are daisy chained together, then you have the equivalent load of one 4 ohm cabinet.

Total load on channel

Example (left channel shown):

The left channel has a 16 ohm load plugged into the top jack and an 8 ohm load plugged into the bottom jack. The bottom jack load is 8 ohms because the two bottom 16 ohm cabinets are daisy chained together which doubled the load. When a load is doubled, the impedance (ohms) drops proportionally (divides in half).

Looking at the chart, you can see the total load on the two left channel jacks = 5.33 ohms. This value is not in the shaded gray area making it OK to use.
