Impedance Matching

KAD-2BT is capable of 4-16Ω impedance output if more than one speaker is to be connected to the amplifier per channel. Please ensure the total impedance of the speakers are within the range.

Speakers can be wired in two different ways, in parallel or in series. The total impedance can be worked out by the following formulas for the two different ways of wiring:

Parallel Connection

• 1/R_total = 1/R₁ + 1/R₂ + 1/R₃…….

Series Connection

• R_total = R₁ + R₂ + R₃…….

Installation

Before installation, please ensure power is switched off and mains unpluged from the wall to avoid damage to equipment and installer.

Wire speakers to the amplifier as shown above, ensure the positive and negative terminals are wired correctly. Audio input on the back is through 3 pairs of RCA connectors, ensure left and right signals are correct for stereo output. Finally insert the IEC plug and connect the unit to the mains. Before switching on, always ensure the master volume is set at the lowest point to avoid power surge damage to the unit or speakers. Adjust the volume accordingly to an appropriate listening level.
