Design and Function

The unit is a 5” bi-amplified powered studio monitor with two Class-D amplifiers; one for the low frequencies, and one dedicated to the highs. A magnetically shielded 5” low frequency transducer and a 1” soft-dome high frequency transducer are also included in the monitor’s design. On the rear panel there are dual balanced XLR and 1/4” TRS inputs and individual trims for LF and HF, -2db and +2db for maximum versatility.

Sure! Google "Monoprice 1/4in (6.35mm) TRS Stereo Plug to RCA Jack Adapter, Gold Plated" and you can score a pair for about $0.80 plus shipping. Add to it a pair of RCA interconnects -- Monoprice is a good source for basic ones like "Monolith by Monoprice 3ft RCA Cable" -- and you are in business. (You would need to order two of these.) I ordered my interconnects from Emotiva and do like them. Just make sure that the interconnects are two completely separate ones rather than a pair fused together. Now, I'm going to blow your mind. If I put my ear an inch from the tweeter, I can hear a tiny bit of amplifier hiss. Interestingly, I hear more hiss on the speaker where I am using an extension cord with the included power cord. If I switch to my premium power cord that made clear improvements to my DAC, the hiss is more audible and more complex. Cables do matter! If I plug the speaker directly into the wall or into one particular power strip, the hiss is louder and more complex. If I plug into another power strip, it's much better. HOWEVER, none of it is perceptible as far as I can tell at this point for anything like normal listening. You might have a hissy speaker, or you might just have a grungy power supply or power strip, or both. You should experiment a bit and maybe try an inexpensive power conditioner intended for audio that you can return if it doesn't help. Or you could listen to another pair at a pro audio outlet near you -- take your current ones with you for comparison -- and sell the ones you have if they are fundamentally flawed. Good luck taming that hiss!
