Display "E-01" Informations When the inside of the unit is overheating.  [. . . ] B: Sets the cutoff frequency when the "FILTER" switch is set to "HPF". Sets the cutoff frequency when the "FILTER" switch is set to "LPF". 
                      
^ FILTER switch (B. ch)
   
Controls the unit power. Be sure to connect it with all the systems.

· HPF (High-Pass Filter) position:
  
When you wish to use the unit as a stereo amplifier,  stereo connections are used. The speakers to be connected should have an impedance of 2 or greater. When multiple speakers are to be connected,  ensure that the combined impedance is 2 or greater for each channel. When you wish to use the unit as a high-output monaural amplifier,  bridged connections are used. (Make connections to the LEFT channel 9 and the RIGHT channel · SPEAKER OUTPUT terminals. ) The speakers to be connected should have an impedance of 4 or greater. When multiple speakers are to be connected,  ensure that the combined impedance is 4 or greater. 
2CAUTION

The filter outputs the band of higher frequencies than the frequency set with the "HPF FREQUENCY" control. The entire bandwidth is output without filtering. The filter outputs the band of lower frequencies than the frequency set with the "LPF FREQUENCY" control. The speaker output is automatically switched to monaural (L+R).
