RDL RU-MLD4 Reviews

Feels like Pro, But...

Sadly this unit was not as good as I was hoping. There does not seem to be much headroom on the unit before distortion occurs. Also the instruction paper that comes with the unit is not very intuitive. Seems translated... This unit does have detachable terminal blocks on the back. I have never used these, but I guess if needed they could be very useful. BEWARE this unit does NOT come with a power cord! $ additional...

his is a great little box

We us this to amplify and distribute director communication to CCUs and for our application it worked great Only drawback is they do not include a power supply for the product you end up searching for good PS and its difficult to find

See any errors on this page?

this amplifier is 110 or 220v ?

this amplifier is 110 or 220v ?
Asked by: Robert Albert
The RDL RU-MLD4 - 1x4 Mic/Line Distribution Amplifier does require a 110 or 220V power source but rather uses a 24 to 33 VDC @ 80mA source via terminal block wiring or optional power supply. The RDL PS-24AS Switching Power Supply (BH #RDPS24AS) is available as a separate item for use with the RU-MLD4 and specifies compatibility with source connections between 100-240VAC: https://bhpho.to/39KBnoY

question

Will this impedance match 3.5mm input to 600ohm output?
Asked by: Anonymous
The RDL RU-MLD4 is a distribution amplifier capable of splitting a mic/line signal four ways without signal loss or depreciation. It unfortunately will not match the impedance of a 3.5mm input to a 600 ohm output.
