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.
3
Output voltage switch
This switch is used to change the output voltage
between 70V and 100V.

Refer to “Speaker connections (XH200)” on page 10 for
more information on the impedance of speaker systems
that can be connected to these terminals.
6
GND terminal
If you are having a problem with hum or noise, use this
terminal to connect to ground (earth) or to connect to
the chassis of a mixer, preamp, or other device in your
system.

Connect one plug of the included AC cable to this inlet.
Connect the other plug of the AC cable to an AC outlet
that meets the power supply conditions printed on the
label at the top of the unit.

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
