MONITOR OUTPUT (P)
The graphic input jack provides a means to allow patching into the internal graphic equalizer /power amp. This jack is of the switching type that
normally picks up the signal trom the main outputjack (Q). When a plug is inserted into the graphic input,
the circuit path is broken and this input may
owe plugged into other devices or any of the output jacks of the XA-400. The graphic input provides m u c h greater llexibilty in allowing the internal
graphic//power amp to be utilized as a monitor
amp or for any other purpose the user may deem necessary. lis input impedance is approximately
50K ohms at approximately 1-volt signal level for full power output at the speaker jacks.

POWER SWITCH (T)
(On domestic units, the power switch is of the three-position type with the center position being "OFF." This switch has two "ON" positions, one
of which is used to ground the amplifier properly. One of the ON" positions wil yield the lowest amount of residual hum or "popping" when the
instrument is touched and this is the position that should be used
On export models, we utilize a simple on/off switch that does not have multiple "ON" positions since the grounding (earthing) conditions in
most foreign countries are positively made through standard tamper-proof plug-in systems.
LINE CORD (U)
For your safety. we have incorporated a three-wire line (mains) cable with proper grounding facilities.

LINE (MAINS) CORD RETAINER (W)
We have provided two large molded line cord retainers on the rear panel tó allow storage of the mains cable for travel In operation, the cable
should be completely unwrapped to allow maximum heat dissipation from the,rear nanel/heatsink
