Mackie Mix 260FX Owners Manual - Page 14

INTERNAL EFFECTS The internal effects circuit receives a mono signal from the AUX 2 FX bus, and it outputs a stereo signal onto the main mix buses. The input signal is controlled by the MASTER AUX SEND 2 knob [28] and the FX INPUT LEVEL knob [36], while the outputs are controlled by the FX RETURN [32] knob. Inside the processor, the analog audio is converted to digital, this is processed by the internal DSP effects processor, and the result converted into a stereo analog signal. 34. Internal Effects Select Knob The internal effects processor has 16 great preset effects to enhance your sound, confuse cats, and upset hamsters, if that is your idea of fun. Each has been carefully modeled to represent standard effects. Note that the effects output mutes momentarily when changing effects. 37. FX OL This LED indicates when you are approaching the clipping point for the digital effects processor. If you see the FX OL overload light blinking frequently, turn down the FX INPUT LEVEL knob until it just turns off during the louder passages, riffs, chords, yells, etc. 38. FX BYPASS Press this switch in to bypass the internal effects processor, and so prevent its output from appearing on the main mix or stage monitors. The LED next to the BYPASS switch reminds you whenever the processor is bypassed. Use BYPASS if you are not using the internal effects, or use it to quickly compare between the effective effect of effects and the effect of no effects. MAIN MIX, SUBS, and POWER LEDs 35. VARIATIONS As you rotate this control from position 1 through 16, the "strength" of the effect increases. For example, if using a reverb effect, a low number produces a short reverb time, and a larger number produces a longer reverb time. 36. FX INPUT LEVEL This knob allows you to adjust the signal level going into the internal effects processor. As a general rule, adjust the FX INPUT LEVEL knob until you just barely see the FX OL LED [37] blink. This will give you the best signal-to-noise ratio for the effects signal. 39. ALT 3-4 Master Faders (Mix.220FX) These faders control the level of the signals sent to the ALT 3-4 OUTS [53]. Remember, channels are routed to the ALT 3-4 OUTS when their MUTE/ALT 3-4 switch is pushed in (Mix.220FX only). 40. SUB 1-2 Master Faders (Mix.260FX) These faders control the level of the signals sent to the SUB OUTS [54]. All channels that have their Sub 1-2 assign switch [18] pushed in appear at the SUB OUTS (Mix.260FX only). LOOK CLOSER The ALT 3-4 and SUB 1-2 signal is off when the faders are fully down, the "U" marking is unity gain, and fully up provides 10 dB of additional gain. If you are using the two ALTS or SUBS as a stereo pair, make sure that both faders "ride" together to maintain the left/right balance.

SUB ASSIGN TO MAIN MIX Switches (Mix.260FX only) One popular use of the subgroups is to use them as master faders for a group of channels on their way to the MAIN MIX. Let's say you've got a drum kit using several channels and you're going to want to adjust the overall volume of just the drums with two master faders. Just un-assign these channels from the MAIN MIX, reassign them to subgroups 1-2, engage the SUB ASSIGN TO MAIN MIX LEFT on subgroup 1 and SUB 14
