Guided Tour - Rear Panel
1: Fan - This variable-speed fan provides vital cooling to your S500 (the hotter the amp gets, the faster
the fan blows!). Make sure that both the front and rear panels are kept free of all obstructions and that
cool, fresh air is accessible at all times. Also, try to ensure that the S500 is used in a dust-free environ-
ment.
2: Circuit Breaker - This circuit breaker will trip if there is a fault with the mains voltage or if maximum
output is exceeded (very highly distorted). Push it in (once only!) to restart the amplifier.
3: AC input - Connect the supplied heavy-gauge 3-pin “IEC” power cable here.
4: Banana output connectors - Use these to connect each channel of the S500 to 4- or 8-ohm loud-
speakers. Be sure to connect the loudspeaker correctly, with the red (+) terminal normally connected to
the positive input of the speaker and the black (ground) terminal normally connected to the negative
input of the speaker. See page 7 in this manual for more information about Bridged mode and pages 8
and 9 in this manual for full speaker connection instructions.
5: Speakon™ output connectors - Alternatively, you can use these to connect each channel of the
S500 to 4- or 8-ohm loudspeakers. See page 7 in this manual for more information about Bridged mode
and pages 8 and 9 in this manual for full Speakon™ connector wiring and interconnection instructions.
6: Bridged / Stereo / Parallel switch - For normal operation, place this three-way switch in its center
(“STEREO”) position. When placed in its right (“PARALLEL”) position, the signal arriving at the
Channel 1 input only is routed to the power amplifiers of both Channel 1 and Channel 2 (the Channel 2
input is ignored), with each power amplifier delivering 250 watts into 4 ohms. When placed in its left
(“BRIDGED”) position, the signal arriving at the Channel 1 input only is again routed to both power
amplifiers (again, the Channel 2 input is ignored), but the two power amplifiers are bridged together, pro-
viding a full 500 watts of power into 8 ohms. For more information, see the “Bridged and Parallel
Modes” section on page 7 in this manual and the “S500 Connections” section on pages 8 -9 in this man-
ual. WARNING: Due to the extremely high power output of the S500 when used in Bridged mode,
be sure to use only loudspeakers sufficiently rated to handle the resultant wattage (in Bridged
mode, these must be 8-ohm speakers).
7: Input connectors - Connect incoming signal to these electronically balanced Combination
connectors, using either XLR or 1/4" TRS (Tip/Ring/Sleeve) plugs, wired as follows: Pin 2 (or Tip) hot,
Pin 3 (or Ring) cold, and Pin 1 (or Sleeve) ground. We recommend the use of balanced three-conductor
cabling wherever possible (unbalanced two-conductor 1/4" plugs can also be inserted into these inputs,
but you’ll get better signal quality and less outside noise and hum if you use balanced lines).
The S500 accepts input levels of any strength but needs at least 0 dBu to achieve maximum power.
Stereo signals should be connected to both the Channel 1 and Channel 2 input jacks; however, when
operating the S500 in Bridged or Parallel modes, use the Channel 1 input jack only. See page 7 in this
manual for more information about Parallel mode and pages 8 and 9 in this manual for full interconnec-
tion instructions.
8: Link connectors - These XLR connectors provide unity gain outputs, allowing the S500 to be daisy-
chained to additional power amplifiers. Wiring is as follows: Pin 2 hot, Pin 3 cold, Pin 1 ground. See
page 9 in this manual for more information.
