Mackie SR408 / SR568 Owner's Manual - Page 36

SOLO LEVEL Point Before: INPUTS PFL/AFL and OUTPUTS PFL/AFL switches. Point After: HEADPHONES and MONITOR . This controls the signal level of all SOLO signals, be they from the INPUTS, OUTPUTS, PFL, or AFL. The signal is off when turned fully counterclockwise, with 10dB gain turned fully clockwise. Remember, PFL signals are tapped before the circuit's level control. For instance, when soloing a Channel in PFL mode, the signal will be tapped before the Channel's Fader. If you have a Channel's Fader set way below "U" (unity gain), SOLO won't know that and will send a unity gain signal to the PHONES. That may result in a startling level boost, depending on the position of the SOLO LEVEL control. In other words, you may find yourself tweaking this control quite often - that's why we put it next to your right hand. RUDE SOLO LIGHT This flashing LED serves two purposes - to remind you that you're in solo, and to let you know that you're mixing on a Mackie. No other company is so concerned about your level of solo awareness. In addition to this huge LED, each SOLO switch has a local LED adjacent to it, to help you find that pesky soloed Channel right away. PHONES LEVEL Point Before: LEFT/RIGHT/CENTER mixes post-Fader outputs Point After: HEADPHONES and MONITOR . Unless the SR40•8 is in SOLO, the HEADPHONES always receive the LEFT/RIGHT mix, with the CENTER mix blended into each side. This control sets the level for those signals only. SOLO signals are controlled by SOLO LEVEL only - PHONES LEVEL has no effect on SOLO signals, even though they are being sent to the headphones. This is so you can tailor the "mix level" (non-SOLO signals) and the SOLO LEVEL independently. WARNING: The SR40•8's stereo phones jack will drive any standard headphone to very loud levels. When we say the headphone amp is loud, we're not kidding. It can cause permanent ear damage. Even intermediate levels may be painfully loud with some earphones. BE CAREFUL! Always turn the PHONES level all the way down before connecting headphones. Keep it down until you've put the phones on. Then turn it up slowly. Why? "Engineers who fry their ears find themselves with short careers." The SR40•8's headphone amplifiers will drive headphones of any impedance, but for best results (highest volume), use 60-ohm headphones.
