Rear Panel

Rear Panel

1. AC POWER INPUT TERMINAL

It supplies power to this device. The power source is Ac 220 V, 60 Hz. do not bend, pull, twist, heat, or cut
the power cord excessively. It may damage the cord and cause a fire or electric shock.

2. SPEAKER OUTPUT TERMINAL

It is a terminal to connect with the speaker(s). 

After connecting with the speaker(s), carefully keep them from being overloaded when you use them.

You can control the sP 1~5 terminals by using the speaker selection switches in front or the cH 1, 2, 3,
4, and 5 buttons of the rM-05A.

before connecting with the speaker(s), unplug the power cord. Then, connect the speaker(s) to use with
the speaker terminal(s) in the rear panel according to the following methods.

caution: When installing the system, make sure that the total impedance of the speaker(s) does not fall
below  the  regulated  impedance  under  all  circumstances.  Impedance  and  low  output  voltage  are  listed
below.
