2A Tour of the MultiMix FireWire

In this chapter, you’ll learn all about the MultiMix’s components (except for the digital effects processor, which is explained in the next chapter). Please refer to the diagrams as you read each section to see which components we’re talking about.

Patchbay

At the rear portion of the top of the MultiMix, you’ll find the patchbay. This is where you plug in instruments, signal processors, multitrack recorders and other devices. Whatever you need to connect to the mixer, this is where it’s done. In the following paragraphs, we tell you all about the inputs, outputs, switches and knobs you see in this section of the mixer.

Mic Inputs (Channels 1 – 4)

The MultiMix uses standard XLR-type mic inputs. These provide +48V phantom power that you can turn on and off with the Phantom On switch located on the rear of the mixer. You probably will have to turn on the phantom power when you’re using most condenser mics, as these usually require the extra voltage (unless the mic has its own power source, such as a battery). Dynamic and ribbon mics don’t require phantom power and are unaffected when the power is on.

These high-quality mic inputs also feature up to 50dB of preamp gain that you can adjust with the Gain knob.

Another useful feature of these mic inputs is a high-pass filter (HPF) that can be turned on and off with the HPF switch. When you activate this switch, all frequencies below 75Hz are cut from the signal. This is useful for mic or line signals that don’t have much bottom end, such as vocals, snares, cymbals and electric guitar. You’ll want to leave this inactivated for instruments like basses and kick drums.

Line Inputs (Channels 1 – 4)

The line inputs, marked LINE IN, are balanced 1/4” jacks that offer the same 50dB of preamp gain and the high-pass filter provided by the mic inputs (however, phantom power does not apply to line inputs). These inputs accept line-level instruments such as keyboards and drum machines. If you find that your instrument has a weak line signal, just plug it into channels 1 – 4 and crank it up with the Gain knob.

Although chances are your microphones will work fine with these mic inputs, we recommend that you do some checking up on the type of microphone you’re using, especially if it’s one of the older vintage models. Verify that your microphone requires phantom power and make sure its output is low impedance, balanced and floating.

Always connect your microphones before activating phantom power. Microphones tend to be very sensitive, and the sudden power surge can do permanent damage to the mic’s circuitry. It’s also a good idea to lower mixer levels before you activate phantom power.

12 FireWire, 16 FireWire, 12, 16 specifications

The Alesis 12 FireWire and 16 FireWire mixers are innovative audio solutions designed for musicians, podcasters, and audio engineers looking to integrate seamless digital recording capabilities into their workflow. These mixers are equipped with FireWire technology, allowing for high-speed data transfer to computers, which is essential for real-time audio production and recording.

One of the standout features of the Alesis 12 FireWire mixer is its 12-channel configuration, allowing users to connect multiple audio sources, including microphones, instruments, and other audio devices. Each channel is equipped with a 3-band EQ, gain control, pan, and a selectable effect send, providing flexibility for sound shaping. The 16 FireWire model expands upon this, offering 16 channels to accommodate even larger setups for more complex audio routing and mixing scenarios.

Both models feature built-in FireWire interfaces that enable direct recording to a computer without the need for external converters. This integration simplifies the recording process and makes it easier for users to capture high-quality audio in a digital environment. The FireWire connection provides low latency, ensuring that performers can monitor their sound in real-time without noticeable delay.

In terms of build quality, the Alesis mixers are constructed with durability in mind. They feature robust controls, a solid chassis, and a user-friendly layout. This practicality makes them suitable for both studio and live environments, where reliability and ease of use are crucial.

In addition to the essential mixing capabilities, both models support various effects through their built-in processing. The 12 and 16 FireWire mixers come with several onboard effects such as reverb and delay, allowing users to enhance their audio without needing additional outboard gear.

Furthermore, these mixers support phantom power, enabling the use of condenser microphones that require additional power to operate. This feature is particularly advantageous for recording studios and live sound applications.

Overall, the Alesis 12 and 16 FireWire mixers are powerful tools that cater to the needs of modern audio professionals. Their integration of FireWire technology, extensive channel options, built-in effects processing, and user-friendly design make them an excellent choice for anyone looking to elevate their audio production capabilities. Whether you are working in a studio or performing live, these mixers deliver the quality and versatility needed to achieve outstanding sound.
