BEFORE USING YOUR AMPLIFIER
Always ensure the amp’s volume control(s) are set to zero before switching on the power to amplifier.
To prevent hum and electrical noise operate your amplifier and instruments as far away from other electronic devices (especially fluorescent and neon lamps) as possible as these generate extremely high levels of electronic noise.
Make sure the correct speaker load is connected at all times during operation in one of the following configurations:
• 1 x 8 Ohm cabinet – Use either speaker output (rear panel).
• 2 x 8 Ohm cabinets – Use both speaker outputs (rear panel).
• 1 x 4 Ohm cabinet – Use either speaker output (rear panel).
IMPORTANT NOTES FOR CONNECTING SPEAKER CABINETS:
• Do not use two speaker cabinets of mismatched impedance!
• Do not connect a speaker load which is less than 4 Ohms!
• Always connect to a speaker cabinet(s) of suitable power handling!
• Only connect speakers using a quality dedicated Speakon connection. Never use an instrument cable!
Failure to observe these points may cause damage to both the amp and cabinet(s).
Note: A speaker must remain connected when the DI Output and/or Line Output is in use.
VENTILATION and RACK MOUNTING:
Rack Units: 2U 19″
4-Stroke series amplifiers must remain sufficiently ventilated at all times. During sustained periods at high volume levels the internal fan will start operate and may be audible. Do not obstruct the fan or the cooling vents.
QUICK START GUIDE
The parametric mid controls are powerful tone-shaping tools and can be used to broadly affect the midrange response of your rig, or to fine-tune a narrow range of frequencies to your taste. ‘Cutting’ the frequencies you don’t want to hear can often be more effective than ‘boosting’ those you do want to hear.
There are no rules to using EQ, but you will learn how to quickly access the most usable tones within the pedal and help your ears tune to how the controls interact. However, experimentation can unearth some seriously far out sounds!
Rear Panel Features
|1. Balanced Output||Sends a balanced, line-level signal (post-EQ and post-volume) to a mixer or PA system. Engage the ground LIFT/GND button if ground hum becomes a problem when connecting the amplifier to external equipment.|
|2. Line Output||Sends an unbalanced, line-level signal (post-EQ and post-volume) to a mixer or PA system.|
|3. Fan Intake||Do not obstruct or place objects into the fan! During sustained periods of high volume playing the fan will begin to operate to help cool the amplifier.|
|4. Speaker Outputs||Refer to ‘Before Using Your Amplifier’. Make sure the correct speaker load and power handling is connected!|
Total minimum impedance = 4Ω (Ohms). Speaker outputs are wired in parallel (Speakon connector only).
