SA-4200™ Power Amplifier
Description
Keeping with the Sanctuary Series creed, this four-channel power amplifier solves common audio problems with exclusive Peavey
technology. Built-in Auto Delay™ automatically measures and sets the proper delay time for fill loudspeakers, eliminating the
frustrating delay and phasing problems experienced in many houses of worship.
The SA-4200 also features four channels rated at 200 watts each into 4 ohms or 70 volts (selectable in two-channel pairs). This
versatility makes the SA-4200 ideal for delivering power to both main and balcony/fill loudspeakers and any application requiring
multiple audio zones, such as cry rooms or paging systems in larger houses of worship.
Features
• Four-channel power amplifier system rated at 200 watts RMS per channel
• Low-Z (4 or 8 ohms) or 70V outputs selectable in two-channel pairs
• Patent-pending, proprietary built-in Auto Delay circuitry
• Dedicated XLR-type, electronically balanced input connectors
• Low-cut filter on each channel
• Front panel detented level controls
• Front panel AC power switch/circuit breaker
• Short circuit, thermal and DC load protection circuitry
• Rugged, 2U rack-mount design
• Two-speed, fan-cooled patented heat-management design (U.S. Patent Number 6,515,859)
• Signal and clip LED indicators for each channel
with security cover
on front panel
Unpacking
Upon unpacking, inspect the amplifier. If you find any damage, notify your supplier immediately. Only the consignee may institute
a claim with the carrier for damage incurred during shipping. Be sure to save the carton and all packing materials. Should you ever
need to ship the unit back to Peavey Electronics, one of its offices, service centers or the supplier, use only the original factory
packing. If the shipping carton is unavailable, contact Peavey to obtain a replacement.
Mounting
The SA-4200 amplifier will mount in standard 19” E.I.A. equipment racks.
Security Cover
A security cover is provided to prevent inadvertent level adjustments. It is designed to permit monitoring of the various LEDs
without removal. To remove the cover‚ simply remove the Phillips-head mounting screw.
Cooling Requirements
The SA-4200 amplifier uses a forced-air cooling system to maintain a low, even operating temperature. Air is drawn into
the amplifier via a fan located in the back of the unit and courses through the cooling fins of the tunnel-configured channel
heat sinks. The air then exits through the front panel slots. If the heat sinks get too hot‚ a sensing circuit will activate the
protective muting system to protect the amplifier. When the internal temperature reaches a safe level‚ the amplifier will
automatically return to normal operation. It is important that both the front and rear of the unit have enough space to allow
the cooling air to enter and escape. If the amp is rack mounted, do not use doors or covers on the front of the rack; the
intake air must flow without resistance. If you are using racks with closed backs, make sure that there is one (1) standard
rack space opening for every three mounted power amplifiers. If not rack mounted‚ allow 6” of clearance on all sides.

Operating Precautions
Make sure the mains voltage is correct and is the same as that printed on the rear of the amplifier. Damage caused
by connecting the amplifier to improper AC voltage is not covered by any warranty.
Note: Always turn off and disconnect the amplifier from mains voltage before making audio connections. Also, as an
extra precaution, have the attenuators turned down during power-up.
It is always a good idea to have the gain controls turned down during power-up to prevent loudspeaker damage if
there is a high signal level at the inputs. Whether you buy or make them, use high-quality connections, input cables
and loudspeaker cables along with proper soldering technique to ensure trouble-free operation. Most intermittent
problems are caused by faulty cables.
Consult the Wire Gauge Chart (below) to determine proper gauges for various load impedances and cable lengths.

Remember that cable impedance robs amplifier power in two ways: power lost directly to resistance (I
R loss) and
by raising the total load impedance.

1. POWER INDICATOR:
The green LED indicates that AC power is supplied to the unit‚ the power switch is ON and the unit is
functional with no faults. If the amplifier has a thermal fault condition‚ this LED will not illuminate.
2. SIGNAL INDICATORS:
Yellow LEDs indicate signal presence at that specific channel output (identical on each channel).
3. CLIP (DDT™) INDICATORS:
Any time a channel is driven into hard, continuous clipping, the DDT circuit will automatically reduce the
channel gain to a level just slightly into clipping, guarding the loudspeakers against the damaging high power
continuous square waves that may be produced. Situations that may activate the DDT circuit include
uncontrolled feedback, oscillations or an improper equipment setting or malfunction upstream from
the amplifier. On the SA-4200™, normal program transients will not trigger DDT; only steady, excessive
clipping will. The LEDs will illuminate red when the DDT circuitry is active (identical on each channel).

4. INPUT LEVEL CONTROLS:
These controls adjust the signal level to the power amplifier inputs. Maximum input sensitivity is achieved
at the fully clockwise setting. These controls are detented to allow the input sensitivity of the channels to
be closely matched. This is essential in the bridged-output mode. See MODE CONFIGURATION on pages
18-21.
5. AC POWER SWITCH/CIRCUIT BREAKER:
The SA-4200 amplifier has a combination AC switch/circuit breaker on the front panel. If the switch shuts
off during normal use, push it back to the ON position once. If it will not stay on, the amplifier needs
servicing.
6. COOLING AIR VENT:
The SA-4200 is designed to operate under extreme conditions. Part of this design includes the air vents
visible from the front of the unit. These openings should never be blocked.

7. AC MAINS POWER RECEPTACLE:
This is a standard IEC power connector. An AC mains cord with the appropriate AC plug and ratings
for the intended operating voltage is included in the carton. The mains cord should be connected to the
amplifier before connecting to a suitable AC outlet.
AC MAINS CORD:
The mains cord supplied with the unit is a heavy duty‚ three-conductor type with a conventional
120 VAC plug with ground pin. Never break off the ground pin on any equipment. It is provided for
your safety. If the outlet used does not have a ground pin‚ a suitable grounding adapter should be
used and the third wire should be properly grounded.
8. CHANNEL A/B OUTPUT MODE SELECT (low-Z or 70 volt):
This slide switch allows channels A and B of this amp to be configured for either conventional low-Z or for
a 70 volt distribution loudspeaker system.
13
9. CHANNEL C/D OUTPUT MODE SELECT (low-Z or 70 volt):
This slide switch allows channels C and D of this amp to be configured for either conventional low-Z or for
a 70 volt distribution loudspeaker system.
10. CHANNEL A/B OUTPUTS:
The outputs are screw-type for channels A and B. Connect the loudspeaker system to the respective
positive and ground terminals. These outputs may also be used in BRIDGE Mode for a single output. See
Dual/Bridge Mode Switch (14) and MODE CONFIGURATIONS below for more details.
11. CHANNEL C/D OUTPUTS:
The outputs are screw-terminal type for channels C and D. Connect the loudspeaker system to the
respective positive and ground terminals.
12. FAN GRILLE:
A two-speed DC fan supplies cool air to the amplifier. This intake should never be blocked. The fan
automatically switches to high-speed when the unit requires additional cooling. When the amplifier is
relatively cool and at idle‚ the fan should operate at low speed. The fan should never stop unless the
amplifier is switched off or the AC mains power source is interrupted.
13. CHANNEL INPUTS:
These female XLR jacks allow for electronically balanced line-level input signals to be connected to the
system. Each input has a sensitivity of approximately 1.4 volts. Pin 2 is positive, Pin 3 is negative, and Pin 1
is ground.
