This ATT-448 from Hosa is a switchable input attenuator for stepping-down an input level to a mixer when that level is too high. For instance, a hot microphone in front of a loud source will "peg the meters" at the board and cause audio distortion.

The ATT-448 attenuator is placed in-line between the microphone and the board and the appropriate amount of attenuation switched in. The choices are 20, 30, or 40dB of signal reduction, for a wide range of uses on stage and in the studio.

The unit accepts the appropriate male and female XLR connector.

Provides 20dB, 30dB or 40dB of microphone attenuation
For use with all low-impedance and phantom-powered condenser microphones
XLR input and output
Full magnetic shield case

    ATT-448 In-Line Attenuator is rated 4.5 out of 5 by 36.
    Rated 4 out of 5 by from When you need one, you need it... We use this to drop 600 ohm balanced line level signal levels from a theatrical house mixer output so it can feed one channel of our video camera.The switchable attenuation makes it handy to accomodate various signal levels, but I am a bit concerned about the long term reliability of the multi-position switch. (this depends on a bunch of variables - oxidation, contact pressure, self wiping action, circuit design - is it a T or H circuit? - where is the switch used in the circuit? - etc.)It is certainly more predictable than the Rolls SLC 19 which it replaces. That unit has a noisy potentiometer and is difficult to set in a repeatable manner.

    Rated 3 out of 5 by from a cheap switch, but does the job I patch in my Alesis mixer to many different sound systems on the road. Many have microphone inputs with no adjustable gain or input pads. My mixer output distorts these inputs, so I needed a pad. The Hosa was the only one in stock, so I bought it. It does the job, but the switch that varies the level of pad is very cheap and moves too easily. I will have to tape it down so it is not switched accidentally during a show. That is why I give it 3 stars, for the cheapness of construction. But so far it has done an acceptable job.

    Rated 5 out of 5 by from No more distorted sound The signal from the mixer board in my church was too hot for my Sony UTX-P1 plug-in transmitter. (The signal was too hot for the mic level setting, causing constant peaking and distortion even with the highest level of attenuation in the UTX-P1, but the signal was too weak for the line level setting.) The Hosa ATT-448 did the trick. Setting it at a 30 decibel attenuation provided just the right level of attenuation. Now my sound is very good and undistorted. This was just what I needed. Two of these Hosa ATT-448 in-line attenuators will travel in my gear bag from now on. The price is right, and they are made in Taiwan, which in my experience generally means a high level of quality.

    Rated 4 out of 5 by from Good function, simple design We use this attenuator between our sound board and monitor speaker, as the levels from the board are considerably higher than needed. The attenuator allows us to have the monitor send level at a more reasonable point and avoid feedback if someone bumps the level too high. In the long run we will use fixed attenuators in this role, as they are less prone to error. The variable nature of this attenuator is ideal for determining the optimal attenuation to use, but a fixed unit the avoids accidental change. So we recommend this item as a good tool bag item for fixing situations on the fly, but recommend fixed-level attenuators for use in systems that are used on a regular basis.

    Rated 5 out of 5 by from This is great! After using hand-made pads for most of my career, I decided to buy a couple of new pads. I couldn't be happier with these. I use two medium or short mic cables and put the pad in-between them. That way the pad lies on the floor and is not hanging out of the mic, mic-pre, or outlet. The switch is easily adjusted with just your finger, the pad works with phantom, and sounds great. I have two mics that are very high output, and these pads allow me to not have the preamp all the way down, which sometimes still wasn't low enough. 5 stars from me.

    Rated 4 out of 5 by from Works as described I use these to reduce the gain on outputs from a soundboard to feed an H4N recorder. The attenuator switches function well. Although the items feel a bit light, the construction seems good. The fit is a little snug on the inputs to the H4N due to the thickness of the barrel at the connector - otherwise very pleased with my purchase for the relatively low cost.

    Rated 5 out of 5 by from Excellent. Retains phantom power, great in an inline unit. The switchable pad is great for me because I record cars at the track, where cars are of widely varying volumes. Only thing I didn't like was the male end does not fit into the female xlr jacks on Zoom H4n's, as the casing is a bit too thick.

    Rated 5 out of 5 by from WORKS WELL WITH SHURE MX418/C At our church we run a very hot, Shure MX418/C pulpit mic into a Peavey XR684 Mixer which has no mute button, only a 25db down button. Without this Hosa ATT-448 Attenuator I had to run the 25db down all the time and if I released it I got feedback. With the attenuator set at 20db that mic channel works fine, just like the others. I will tape the switch some time to make sure it stays in place but I think it would be OK without the tape. When money allows we hope to upgrade to a Peavey XR1212 or XR1220 amp-mixer.
