8 AC Inlet and Fuse holder
Standard IEC receptacle. Connect your X23 to the AC with the supplied AC
power cord. Before powering up your X23 for the first time, make certain
the stated power requirement of the unit matches the voltage supplied by the
AC socket.
If the fuse blows, replaced with a fuse of the correct type only.
9 INPUT 1 & 2
Lettering for 3-way mono operation is into brackets. Standard operation is
2-way stereo. You can feed balanced and unbalanced signals into your X23
through these connectors. For 2-way stereo operation the MODE switch
must be disengaged. If the MODE switch is engaged, you will operate in
3-way MONO mode. In such case only use INPUT ONE to feed the signal
into your X23. Do not use INPUT 2.
10 CHANNEL 1 HIGH AND LOW OUT
In 2-way stereo operation (MODE switch disengaged), connect these outputs
respectively to the low frequency and high frequency power amplifiers. In
3-way mono operation (MODE switch engaged) connect LOW OUT to the low
frequency power amplifier. Do not use the HIGH OUT OUTPUT.
11 CHANNEL 2 HIGH AND LOW OUT
In 2-way stereo operation (MODE switch disengaged), connect these outputs
respectively to the low frequency and high frequency power amplifiers. In
3-way mono operation (MODE switch engaged) connect LOW OUT to the
middle frequency power amplifier and HIGH OUT to the high frequency power
amplifier.
12 CD BOOST
High frequencies, even when reproduced by good quality compression drivers
and horns suffer of fast decay. Therefore the sound pressure level of high
frequencies is affected by the distance of the horn from the Audience. With
some large Live applications it may be necessary to boost the high frequencies
to compensate such loss. CD boost stands for Constant Directivity Boost.
Engaging this switch you will produce a boost of 3 dB at 3,5 kHz and then
6 dB x oct up to 22.5 kHz.
13 HIGH PHASE
This switch will produce a phase inversion of 180 to compensate for phase
cancellation.
