BOOST SWITCH & LED
This toggle switch activates the Boost function. The Boost function is on when the switch is in the up position. Boost is active when the LED is lit.
LOOP SWITCH & LED
This toggle switch activates the Loop function. The Loop function is on when the switch is in the up position. Loop is active when the LED is lit.
REVERB SWITCH & LED

CLASS A / STANDBY / CLASS AB SWITCH
Turns on the high voltage to the tubes. The tubes should warm up for at least one minute before turning the standby switch to either Class A or Class AB. Be sure that the Volume control is set to a reasonable position before switching the amp to Class A or Class AB as this amp can be very loud! You are able to switch from Class A to Class AB while the amp is operating.
PILOT LIGHT
This shows that AC Mains voltage is flowing to the amplifier.
POWER SWITCH
Turns on AC power to the amp. The Power switch should be turned on, and the pilot light should be lit for 1 minute before turning the standby switch to ON.

2.2 REAR PANEL

IEC POWER CORD RECEPTACLE / FUSE HOLDER
The power cord connects here and to your country’s appropriate wall outlet. Make sure to connect the male end of the IEC Power Cord to a Grounded Power Outlet. This IEC connector contains the AC Mains fuse. This is a 5x20mm, 3A, 250V Fuse.

SPEAKER OUTPUTS
The Royale provides two 4-Ohm, two 8-Ohm, and one 16-Ohm speaker output. Which output jack you use depends on the configuration of your speaker cabinet or cabinets. For instance, when using a single 8 Ohm speaker, connect the speaker cabinet to one of the 8 Ohm jacks. If using two 8-Ohm speakers or cabinets, plug them both into the 4-Ohm jacks. (Two 8-Ohm loads connected in parallel add up to a 4-Ohm total load). If using a 16-Ohm cabinet, plug it into the 16-Ohm output. A speaker must always be connected to at least one output. Do not turn the amp on without a speaker plugged in.
FOOTSWITCHES
Each footswitch jack is designed to accept a 1/4″ TS cable and a single footswitch.
BOOST SWITCH JACK
Allows remote switching of the Boost function. Insert a standard guitar cable and connect the other end to the footswitch. Note: Plugging into this jack will override the front panel Boost switch function.
REVERB SWITCH JACK
Allows remote switching of the Reverb. Note: Plugging a cable into the Reverb footswitch jack will override the front panel switch position.
EFFECTS LOOP FOOTSWITCH JACK
Allows remote switching of the effects loop. Note: Plugging a cable into the Loop footswitch jack will override the rear panel switch position.
EFFECTS LOOP
The effects loop in the Supro Royale provides a place to insert effects after the gain stages of the pre-amp.
SEND JACK
Sends signal to the input jack of external effects pedals.
RETURN JACK
Receives signals from the output of external effects pedals.

2.3 TUBES
The Supro Royale amplifier is a 100% analog, 100% tube amplifier. There is NO solid state (transistor) devices in ANY audio signal path.

2.4 TROUBLESHOOTING
Super products have been designed for years of trouble-free service. There are many unique protection features to the design. If you are having difficulties, check the following: No sound, but the pilot light is ON
Check to see that the speaker is plugged into the speaker jack (not the footswitch jack). Make sure all knobs are turned up past zero and that the Standby switch is set to operate. As this is a tube amplifier, the tubes take approximately 1 minute to warm up before you will get sound. The Standby switch should be set to standby for this warm-up period. No sound and the lights are all OFF
Unplug the power cord and check the 2.5A, 250V fuse (rear panel). If you have any further questions, our email address is support@suprousa.com.
