F. ACTIVE TONE CONTROLS�Shelving type, 3�band equalization: � BASS�Adjusts low-frequency response ±15dB in the 30Hz�150Hz range. � MID�Adjusts mid-frequency response ±15dB in the 400Hz to 3kHz range. � TREBLE�Adjusts high-frequency response ±15dB in the 2kHz to 14kHz range. G. WEDGE EQ�Use this tone circuit preset when playing the amplifier with the cabinet in the tilt-back position to compensate for the loss of cabinet floor contact and the redirected tweeter horn. H. LIMITER�This circuit protects the power amp and speakers from damage by governing peak signal strength. The benefit is that you to can play at maximum loudness levels without risk. DEFEAT turns the Limiter OFF. I. DEFEATED (LIMITER OFF) LIMITER ON ACTIVE�Indicates exactly when the LIMITER circuit is working (when LIMITER is ON). POWER AMP CLIP�Indicates when the power amp is being overdriven causing signal distortion. Unlike preamp clipping, power amp clipping can be harmful to your equipment. Therefore, if the POWER AMP CLIP LED flashes often, engage the LIMITER or turn down the MASTER Volume {C}. EFX BLEND�Functional only when a plug is inserted into the EFFECTS RETURN {O} jack, this knob sets your effects level by controlling the amount of "wet" effects loop signal blended into the "dry" preamp signal. POWER SWITCH�Switches the unit ON-OFF as indicated by the LED.

Monitor Input Panel
Y. LINE LEVEL MONITOR INPUT�� CAUTION! � For line-level inputs only! Amplified (speaker level) inputs will damage your equipment! Insert a 1/4-inch plug from a line-level audio source such as: �Line Out from another bass rig�expand your output for larger venues, �Monitor Send from a mixing board�mix in some vocals or monitor them separately, �Headphones Out on a CD/MP3 player�for accompaniment (use a stereo-to-mono adapter to hear both channels of your player). MONITOR VOLUME�Adjusts the level of the MONITOR INPUT signal. MUTE {B} also affects the Monitor Input level. Z. TWEETER LEVEL�Sets the output level of the piezo tweeter for the amplifier (not just the Monitor Input). Select: ON for maximum output, �6dB for 50% output, or OFF to mute the tweeter.

IMPEDANCE GUIDELINES�Before changing your speaker setup, a basic knowledge of impedance ratings is essential to the quality of your sound and to the safe operation of your equipment. The general rule is: if you connect a speaker load with a total impedance that's equal to the minimum impedance rating of your amplifier, you'll be OK�as long as the speakers are rated to handle the power output from your amplifier. The illustration shows the impedance totals of different speaker combinations. NOTE: All SWR® bass speaker enclosures, as well as most others, are wired "in parallel" (not series), therefore, this section applies to parallel speaker connections only. same amount of power from your amplifier. All speakers in a group should have the same impedance so that each speaker will receive the

If impedances are different, the speakers with lower impedances will be much louder than the rest. For example, with an 8�ohm speaker and a 16�ohm speaker both connected to your amplifier, the 8�ohm speaker will be twice as loud (and get twice the power) as the 16�ohm speaker. Calculating total power handling capacity and positioning speakers of different impedances becomes complicated! � CAUTION!�Operating with a speaker load below the minimum impedance rating of your amplifier can easily overheat the amplifier and cause damage. Operating above the minimum impedance rating will reduce the amplifier�s maximum power output potential.
