Great little distribution amp. I use it for redistribution of my sub-woofer pre-out, feeding a pair of Velodyne sub's and a Buttkicker amp. The only issue is the included 15V power supply is noisy as all heck with a horrible 60Hz leak. I swapped out the Power Supply with a quality PS and now heavenly audio bliss. Be aware the power requirements are 15VDC, 500ma, with a POSITIVE sleeve. The polarity is unusual.

Exactly what I needed. I am an AV Engineer and this product did exactly what it was supposed to do.

My Yamaha has a sub-woofer pre-out channel which is notorious for being too quiet. The Rolls DA1234-4 provides just the right amount of amplification to the output to enable me to not only hear the sub, but to distribute the sound source to multiple subs around the room. There are multiple forums where Yamaha customers are seeking out a solution to this problem. This device is the answer!

This is a good product. It does what it says it does. It's built solid, which makes it nice for porting from location to location. This Rolls DA134 makes it really easy to balance all channels running to it and through it!

So far so good. I have it set to output mono to feed three 70v amps and use the stereo pass-through to feed an 8 ohm amp for another zone. I also have the 3.5mm port plugged into a cable so the bartenders can use their phones for sound when they really want to entertain the customers. This is a very reasonably priced ADA that works exactly like I hoped.

We use this product to distribute audio from a Mac Mini running iTunes to local amplifier and remote amplifiers. I have a Mac Mini in my living room for the sole purpose I'm running iTunes. Obviously, we want to hear this music through the local amplifier in the living room. We also have Control4 amplifier that distributes audio in other rooms of our house. This terrific product allowed us to distribute the audio coming from the Mac Mini headphone jack to the locations we needed. Runs cool. Sounds Great! Sadly, the evil people in Hollywood FORCE Apple to turn off the audio on the HDMI connector when ever the headphone jack is utilized. This product effectively gets around the 34;Hollywood problem34; for us. Manufactured in Communist China. The negative? 1) There is absolutely no documentation included with the product. 2) No on / off switch.

It seemed to be exactly what I needed, but after a few minutes of use it causes a BUZZ in the signal. Bummer. Hope the manufacturer or someone here has a solution. As described, this is perfect.

Resolved a hum/buzzing sound problem I had when passively splitting one preamp output to four amplifiers.
