K. BASS INTENSIFIER - A new SWR® tone circuit that boosts of a chosen set of low-frequencies combined with a smooth, fast-acting compressor. The boost and compression work in harmony to allow radical boosts in the chosen bass and lower midrange frequencies without the side-effect of overdriving the amplifier circuitry. Once dialed in, it literally intensifies the bass tone in your sound. It can be used as a boost for certain, heavier sections of a tune, or just as a part of your overall preferred sound. ENGAGE - Activates the BASS INTENSIFIER circuit as indicated by the LED . LEVEL - Adjusts the amount of bass boost added by the BASS INTENSIFIER. Hint: Adjust slowly, so you can hear the difference a small amount of this effect can have on your tone. CUTOFF - Adjusts the frequency range boosted by the BASS INTENSIFIER. When fully counterclockwise, only frequencies below ~80Hz are affected. When fully clockwise, frequencies below ~200Hz are affected. To best hear what this control does: 1. Decrease MASTER Volume to half its normal setting (or less). 2. Set LEVEL to maximum. 3. Set CUTOFF to 80Hz. 4. Play a note repeatedly (low �E� or low �A�) and slowly rotate CUTOFF clockwise. You will hear additional frequencies being boosted as you turn the dial, and the overall effect will seem louder because more frequencies are being boosted. As always, your ears are the best judge. Take some time to experiment and hear what works best.
L. LIMITER - This circuit is located after MASTER Volume and before the power amplifier in the signal path. Therefore, the circuit is driven by MASTER Volume. Its threshold (starting point) is preset so you get the maximum overall apparent volume without overdriving the power amplifier or internal speakers. DEFEAT - Disables the internal LIMITER circuitry: LIMITER ON LIMITER OFF (DEFEATED)
ACTIVE - Indicates exactly when the LIMITER circuit is working�only when the LIMITER is ON. POWER AMP CLIP - Indicates when the power amp is being overdriven (clipping) causing signal distortion. Unlike preamp clipping, power amp clipping can be harmful to your equipment. Therefore, if the POWER AMP CLIP LED flashes often, either engage the LIMITER or turn down the MASTER Volume. M. MASTER VOLUME - Use to set the loudness output from your speakers (and headphones) after all other levels are set, including external effects. MASTER Volume does not affect any output levels other than the SPEAKERS {Q} and HEADPHONES {R}. N. POWER SWITCH - Switches power on-off to the amplifier as indicated by the LED.
