WARNINGS AND WARRANTY INFORMATION  
Unpacking: All Wharfedale Pro products are fully tested before leaving the factory.  
After unpacking, please inspect the unit. In the event of any noticed damage due to  
shipping, contact your dealer and the shipping provider immediately to file a shipping  
damage claim. Retain the shipping carton and all packaging material in case the unit  
needs to be returned.  
1.  
READ ALL INSTRUCTIONS carefully and become familiar with the features  
and functions of this product before operating it.  
2.  
3.  
RETAIN THESE INSTRUCTIONS for future reference.  
COMPLY WITH ALL WARNINGS – All warnings and instructions for this  
product should be adhered to.  
4. USING AMPLIFIERS – In order to avoid damage to equipment, it is advisable  
to establish and follow a routine for powering up and powering down a sound system.  
With all system components connected, turn on source equipment (mixers, signal  
processors, record and playback units, etc.) BEFORE powering up amplifiers.  
Transient voltages from powering up source equipment can damage speakers if  
amplifiers are turned on. Make sure that amplifier volumes are set to their minimum  
settings and power up any system amplifiers LAST. It is recommended that all system  
components be allowed to stabilize for several seconds before any source signals are  
introduced or level setting adjustments are made. Similarly, when shutting systems  
down, turn all amplifiers off first, before powering down any other system components.

Getting Started  
1. AC Power Connections  
All S-Series power amplifiers are equipped with an internal AC power supply. Connect the  
appropriate grounded IEC power cable to the power amp BEFORE connecting it to the power  
outlet.  
It is important to allow adequate ventilation to the powered mixer as it may become warm  
during extended periods of operation.  
Each S-Series amp is shipped with the correct power cable for the country in which it is to be  
used. The S-Series amps are NOT to be used in a country using a different source supply  
voltage other than for which it is designed. Note the operating voltage shown near the AC  
power cord jack and ONLY connect this unit to the appropriate AC source voltage.  
2. Packing  
The packaging has been designed protect the mixer during transit. If any shipping damage has  
occurred, consult your dealer and the shipping provider.  
3. Safety  
Avoid excessive heat, humidity, dust and vibration. Store and operate the power amplifier away  
from high temperatures or humidity. Also, avoid locations which may be subject to excessive  
dust and vibration / physical shocks that could cause mechanical damage to the amp.  
WARNING: REFER ALL MAINTENANCE, REPAIRS AND MODIFICATIONS TO QUALIFIED  
SERVICE PERSONNEL! THIS PRODUCT CONTAINS NO USER-SERVICEABLE PARTS!  
For the protection of the amplifier and other audio equipment, always turn off the power on the  
amplifier and other system components before connecting or disconnecting audio cables.  
4. Warranty  
The S-Series power amplifiers are covered, by limited warranty, of any defects in workmanship  
for a period of one year from the date of purchase. This warranty is non-transferable and  
applies only to the original purchaser. If any warranty related issues occur, contact your dealer.

MODE SWITCH OPERATION  
LIMITER  
A limiter is a circuit that prevents signal overload and distortion in an audio signal path. When engaged,  
the internal limiter circuit will keep the audio signal from going over a preset level threshold, thereby  
helping to prevent signal distortion within the amplifier and in the speaker system. The limiter also  
serves to prevent speaker damage. The limiter function can be engaged by engaging MODE  
SWITCHES SW2 (for INPUT A) and SW5 (for INPUT B) in the up “ON” position.  
LO CUT  
MODE SWITCHES SW3, SW4 (for INPUT A) and SW6, SW7 (for INPUT B) provide the options of low  
frequency filtering starting at the 30Hz and 50Hz frequency ranges and frequencies below those points.  
These filters “roll off” the lower bass frequency range to help eliminate unwanted “boominess” in the  
sound system with a -12dB per octave slope. MODE Switch SW4 engages the “LO CUT” filter and  
Switch SW3 selects between the 30Hz (in the up, “ON” position) and 50Hz (in the down “OFF” position).  
INPUT MODE  
The INPUT MODE switches select the operating mode of the amplifier. STEREO mode allows the unit  
to function as a two channel amplifier with each input (INPUT A & INPUT B) routed to a separate  
amplifier output (OUTPUT A & OUTPUT B), respectively.  
PARALLEL mode sums the signals of INPUT A and INPUT B together and routes the combined signal  
to both OUTPUT A and OUTPUT B.  
BRIDGE MODE  
This mode allows you to combine the amplifier outputs for more power. MODE SWITCHES #10, 11  
and 12 control this function. BRIDGE MODE can provide nearly three times more power output than  
operating the amp in STEREO mode.  
When in BRIDGE MODE, only the controls on INPUT A are functional. INPUT B MODE SWITCH  
settings have no affect on the operation of the amplifier when in BRIDGE MODE and the volume control  
for INPUT B should be set all the way down when operating in this mode.  
BRIDGE MODE provides a single 4or 8output for connection to an equivalent speaker impedance  
load. Be aware of the increased power output that BRIDGE MODE provides and be sure that all  
speakers have appropriate power handling capabilities before making connections otherwise speaker  
damage may occur. Speaker wiring for BRIDGE MODE is made via the two middle output binding post  
terminals. See pages 10 and 13 for BRIDGE MODE wiring details.

GENERAL OPERATING INSTRUCTIONS  
Make sure that the power switch is set to the OFF position while making connections to and from  
the power amplifier. Connect all external components. Speakers, Microphones, instruments, etc.  
Check for secure connections.  
Turn all level controls down on mixers, amplifiers and signal processing devices.  
Connect the A/C power cord to the power outlet of the amplifier.  
After powering up all other devices first, turn the power switch on the amplifier to the ‘ON’ position  
and verify that the POWER LED is lit.  
Turn the amplifier volume control up to the “7” setting. (This setting can be adjusted higher or lower,  
as needed, after set-up).  
With the source signal present (a person singing in to a microphone or and instrument playing),  
adjust the various signal levels as needed. Make any needed overall volume adjustments with the  
volume control on the mixer and the amplifier. When powering down, make sure any external power  
amps are switched off first.
