device of some kind, such as a DAT recorder, in order to be mastered and archived. That is a very basic explanation of a mixer, but it will do nicely for now. To get a better idea of what a hardware mixer looks like and how it works, see Figure 6.2. The Mackie 1604 hardware mixer is commonly found in hardware-based recording studios. The 1604 has 16 individual built-in inputs, which simply means that 16 different signals (drums, guitars, vocals, and so on) can be plugged in to it. After these signals have been plugged in, you can then make adjustments to various attributes--such as volume and equalization--on each signal. These signals are then sent, or "bussed" to the master output section of the 1604, and from there, the mix is sent to a pair of speakers and/or a hardware recording device. Over the years, the mixer's interface has evolved into a relatively standard layout. Here are the primary components of just about any mixer: Inputs--Typically found at the top or rear of a mixer. This is where analog signals, such as a guitar or a microphone, are plugged in. Additionally, you will find a Trim knob that amplifies the signal. Auxiliary Sends--These knobs, shown in Figure 6.3, allow you to send a percentage of your dry signal to an external effects processor, such as a reverb for your snare drum, or a chorus for a vocal track. Typically you will find between two and four auxiliaries on a hardware mixer. Equalization--A mixer's EQ section is for boosting or cutting particular frequencies or ranges of frequencies within the signal flowing through a channel. As in Figure 6.4, you will likely find knobs to control the "High EQ," "Low EQ,"
