Euroblock connectors
These balanced Euroblock connectors are used to con-
nect input signals.
2
HPF switches
These switches are used to set the cutoff frequency of
the HPF (High Pass Filter) for each channel. Frequen-
cies below 40Hz or 80Hz are filtered using a 12 dB/
octave high pass filter.
* When the amplifier is set to 40Hz, make sure that the
speaker transformer is capable of sufficiently han-
dling low frequency signals.
Be careful when inputting low frequency signals;
excessive levels at low frequencies may cause
damage to the speaker, speaker transformer or to
the amplifier itself.

● Speaker connections (XH200)
The XH200 enables you to connect in parallel fashion mul-
tiple high-impedance speakers that support 70V or 100V
line output. The number of speakers that can be connected
varies depending on the speaker's rated input. You can con-
nect speakers with a total rated input per channel of up to
200 W.
For example, if you are using speakers with a rated input of
10 W, you can connect up to twenty speakers. If you are
using speakers with a rated input of 20 W, you can connect
up to ten speakers
