BASIC Quick Guide Getting Sound to the Speakers We begin by connecting up two speakers and generating some stereo output. Note that operations and procedures will vary somewhat according to the input devices you are using. 5 3 2,7,9 6 2,8 4 1 1 1 Connect up the speakers and your input devices (microphones, instruments, etc.) Use non-powered speakers and dedicated speaker cable.

BASIC Quick Guide 2 Turn the LEVEL knobs and the MASTER knobs to 0. This position This position 3 Set the POWER AMP switch to its upper position (to MAIN L-R). For information about this switch, see page 25.
BASIC Quick Guide 4 If you have connected input devices to channels 1 to 4, set the LINE/MIC switch on each channel accordingly. If you have connected a line-level device, such as a keyboard or audio device, set the channel’s switch to the LINE position ( ). If you have connected a microphone or other mic-level device, set the switch to the MIC position ( ). 5 If you are using one or more condenser microphones for your inputs, set the PHANTOM switch to the ON position ( ).
BASIC Quick Guide 7 Turn the MASTER knob in the MAIN section to the posi- tion. This position 8 9 Adjust the LEVEL knobs for all occupied channels. For each input device you have connected: Generate sound from the device while adjusting the corresponding channel’s LEVEL knob. Adjust so that the LEVEL meter occasionally reaches the “0” level. Now turn the MASTER knob in the MAIN section again as necessary to adjust the overall output level.
BASIC Quick Guide Adding Some Reverb Now let’s try adding some reverb to your input. The reverb effects let you simulate the sound of different performance environments—such as concert halls and small clubs. 2 3 1 2 4 1 Turn the ON switch to it’s ON position. This switch turns the internal effector on and off. The lamp lights up orange to indicate that the effector is on. As an alternative to the ON switch, you can use a separately sold FC5 foot switch to toggle the effector on and off.

BASIC Making the Most of Your Mixer An Introduction You’ve got yourself a mixer and now you’re ready to use it. Just plug everything in, twiddle the controls, and away you go … right? Well, if you’ve done this before you won’t have any problems, but if this is the first time you’ve ever used a mixer you might want to read through this little tutorial and pick up a few basics that will help you get better performance and make better mixes.
BASIC Making the Most of Your Mixer type connectors will also handle unbalanced signals with no problem. Microphone cables usually have this type of connector, as do the inputs and outputs of most professional audio gear. Balanced noise cancellation Noise Hot (+) In a word: “noise.” The whole point of balanced lines is noise rejection, and it’s something they’re very good at.
BASIC Making the Most of Your Mixer way, but a more systematic approach that is suited to the material you’re mixing will produce much better results, and faster. There are no rules, and you’ll probably end up developing a system that works best for you. But the key is to develop a system rather than working haphazardly.
BASIC Making the Most of Your Mixer If so you might want to build the mix around the vocals. This means bringing the vocal channel up to nominal first (if your level setup procedure has been done properly this will be a good starting point), and then adding the other instruments. What you add next will depend on the type of material you are working with and your approach to it.
BASIC Making the Most of Your Mixer Boost with Caution If you’re trying to create special or unusual effects, go ahead and boost away as much as you like. But if you’re just trying to achieve a good-sounding mix, boost only in very small increments. A tiny boost in the midrange can give vocals more presence, or a touch of high boost can give certain instruments more “air.

Any more than this normally becomes a “special effect.” You don’t want reverb to dominate the mix unless you are trying to create the effect of a band in a cave—which is a perfectly legitimate creative goal if that’s the sort of thing you’re aiming for.
