An unbalanced line does not have this noise-rejecting capability because it has only two conductors. Ear plugs or protectors in the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent hearing loss if exposure is in excess of the limits set forth here. Grounding Grounding exists in your audio system for two reasons: For additional information, see the Global Shipping Program terms and conditions – opens in a new window or tab. Delay 1 has one repeat after the original note. This frequency represents the punch in bass drums, bass guitar, fat synth patches, and some really serious male singers. Decay range adjustable from ms to 1 second. This LED should only light occasionally.

The balanced-to-unbalanced connection has been anticipated in the wiring of Mackie jacks. The circuit is flat no boost or cut at the center detent position. Play something into the selected input. According to OSHA, any exposure in excess of these permissible limits could result in some hearing loss. Make sure it is plugged into the same AC circuit as the powered mixer to reduce the possibility of creating a ground loop. Follow Instructions — All operating and other instructions should be followed. Legendary Mackie circuitry combined with road worthy design and portability result in the ultimate powered mixer.

This amount is subject to change until you make payment. Play something into the selected input. Effects Return to Main Mixer Output: Individual channel inserts and dedicated in-line compressors add even more ways to fine tune your mix.

Make sure the singer is within 3 to 6 inches of the microphone.

If using VAC single phase with center-ground power, connect all audio equipment to one side of the AC power, and all lighting and other equipment to the other side.

Please write your serial number here for future reference i. Duration Per Day In Hours 8 6 4 3 2 1. Pushing in this switch places a low-cut filter into the circuit path, rolling off the frequencies below 75Hz.


Add to watch list Add to wish list. Also works well with keyboards deries drums using short decay.

PAN adjusts the amount of channel signal sent to the left versus the right outputs. A balanced line is a three-wire system where two wires carry the signal and the third is a ground wire that shields the inner conductors from EMI. With no plug inserted, the mixer section and the amplifier section are joined and the amplifiers play serkes mixer signals as normal.

Doing so will affect the internal signal. This is a stereo control, but for the mono versions M, M, Mthe left and right inputs are summed. Tails are normal with strong high end and a slight waver imitating the slow flutter of the mechanical spring system. Decay range adjustable from 2 seconds to 10 seconds. When powering up, turn on the amplifiers last. Here sseries some things you can check: They provide better immunity to induced noise and ground loops. You can create many serids and useful EQ changes by serise this knob down as well as up.

Use it to add sizzle to cymbals, and an overall sense of transparency or edge to keyboards, vocals, guitar, and bacon frying.

It gives an overview of the powered mixer, and the rest of the manual explains the wealth of features and operating instructions in more detail.

For an analog tape delay sound, use a darker setting so that each subsequent repeat is darker than the prior one. If not, make sure the AC outlet is live. The goal is to provide a lower impedance path to ground for noise signals than through the signal wiring. Tails are normal and warm with strong high end for increased presence. This results in painfully audible distortion. Heat from the output transistors is coupled to the heatsink, which draws the heat away from the transistors and out to the heatsink fins.

PPM Series

This completely separates the mixer from the amplifiers, and it allows you to connect an external equalizer, compressor or effects processor in-line between them as shown. Objects have fallen, or liquid has spilled into this Mackie product; or C.


We suggest insurance for all forms of cartage. If you plug two speakers into a side, each speaker must be 4 ohms or greater to maintain a 2-ohm minimum load on the amplifier.

Applications Big sound, small footprint The PPM Series Powered Mixers are an excellent choice for small to medium sized venues or bars that have limited space.

This is not a user-serviceable part.

Skip to main content. Exposure f extremely high noise levels may cause permanent hearing loss. Do not overload or short-circuit the signal you are tapping from the mixer. The power-supply cord or the plug has been damaged; or B. Be sure all AC outlet safety grounds are connected to one common point in a star ground arrangement. Grounding or Polarization — Precautions should be taken so that the grounding or polarization means of this Mackie product is not defeated.

Mackie s FR Fast Recovery Series 8 Ch. Stereo w 9-band EQ FX Powered Mixer | eBay

For the mono versions M, M, Mthe same signal is routed to the inputs of both gr. The balanced input amplifies only the difference between the two conductors.

Doing so helps minimize seriee, buzz, and other extraneous non-audio signals. We recommend leaving at least six inches of air space behind the mixer when you set it up. The Fast Recovery design eliminates this high-frequency sticking and allows the amplifier to remain stable when powering highly reactive loads at high volume levels.

Mackie 408S Manuals

Because a balanced system is able to minimize noise, it is the preferred interconnect method, especially in cases where very long lengths of cable are being used. Conventional designs use lots of negative feedback to provide stability and lower distortion. Since each amplifier is driving nackie speakers in parallel, each speaker must be 4 ohms or greater. When setting up for a show, oftentimes you are plugging into an AC power distribution system you know nothing about.
