Speaker Connections - Yamaha PA24 Owner's Manual

■ Speaker connections

Speakers can be connected to the amplifier as shown below. Note that speaker impedance will vary according to the
connection method and the number of speakers. Please be sure that your speaker's impedance is not less than the relevant
minimum value indicated below.
Connection configurations for STEREO and PARALLEL modes
When using 5-way binding post output jacks
or
Minimum speaker
impedance: 4 Ω
Connection configurations for BRIDGE mode
When using 5-way binding post output jacks
When connecting high-impedance speakers in parallel (PC3301N only)
The number of speakers that can be connected varies depending on the rated input of the speakers. The PC3301N can be
connected to speakers with a total rated input of up to 625 W. For example, if you connect five speakers with a rated input of
5 W (25 W), thirty speakers with a rated input of 10 W (300 W) and twenty speakers with a rated input of 15 W (300 W), the
amplifier can be used with a total rated speaker input of 625 W as shown below:
Be sure to use speakers that support the PC3301N's line-out voltage of 100 V.
