14. IEC POWER INPUT CONNECTOR: This
is where you connect the supplied AC
power cord.
Before plugging in the power
cord, make sure that the Voltage
Selector Switch [15] is set to the same
voltage as your local AC mains�
15. VOLTAGE SELECTOR SWITCH:
Make sure the switch is in the
correct position for your local AC
mains voltage before you plug in the AC
power cord. Use a small, at
screwdriver to slide the switch, if
required�
16. VENTILATION: Make sure that the
ventilation openings are not obscured in
any way to allow the ow of cooling air
to the power amplier’s heatsinks.
17. SPEAKER OUTPUTS: These 1/4" TS
output jacks supply speaker level power
to the speaker cabinet. The rated power
output is 200 Watts RMS into 4 Ω.
The two identical outputs are wired
in parallel, and you can use either
individually, or use both. Make sure the
total speaker impedance load is 4 Ω or
greater�
For example, you could connect:
• Two 16 Ω speakers (an 8 Ω load)
• Two 8 Ω speakers (a 4 Ω load)
• One 4 Ω speaker
Use speaker cables with 1/4" TS
ends to make the connections�
Do not use shielded instrument cables
as they may overheat�
18. EFFECTS LOOP RETURN JACK: Use
this 1/4" TS unbalanced input to return
the processed line level output of an
external eects processor, for example.
The processor could be fed by signals
from the Eects Loop Send [19].
19. EFFECTS LOOP SEND JACK: Use this
1/4" TS unbalanced output to send a
line level output to an external eects
processor, for example. The output here
is aected by all controls except the
Volume [8] and the Limiter switch [9].
Use the Eects Loop Return jack [18]
to feed the returned processed signals
back into the power amplier.
20. XLR LINE OUT JACK: Typically, you
would connect this balanced output
to the balanced input of an external
mixer, or a recorder. In this way, you do
not need to mic the speaker cabinet
in order to add it to the main mix or to
record. The output is not aected by the
Volume control [8].
This output can connect to external
power ampliers, or powered
loudspeakers, as long as they have
their own input controls to adjust the
volume level� Balanced connections
allow long cable runs to be used, as
hum and noise pickup in the line is
minimized�
