This was bought brand new from Carvin. It was used for 2 hours and put right back in its original box. The earphones were not used as I have a set of ultimate ears. This is brand new and will ship in the same box Carvin sent it to me in. All pieces from the manual to the power cord to the earphones and unit it's self are as new. Like I said it was unboxed and used for 2 hours and boxed back up. Brand new condition. This is from Carvin: Carvin EM900 In-Ear Personal Monitor System (638-662 Mhz). Whether you're playing live or rehearsing, you need to hear yourself to be your best. That's what the EM900 In-Ear Personal Monitor System is all about. Ideal for both on stage use and rehearsals, the EM900 is a terrific alternative to cumbersome floor monitor wedges, facilitating greater freedom of movement while enabling one to hear everything in either high fidelity mono or stereo. Performers can use as many as 16 complete EM900 systems simultaneously on stage and any number of EM901 stereo receivers on the same frequency. Carvin's new EM900 In-Ear Personal Monitor System delivers full 30 Hz – 15 kHz frequency response for the most natural audio quality possible—enabling the full dynamic range of the monitored signal to sound exactly as it should. To further ensure the most natural sounding audio quality, the EM900 includes a built-in limiter that keeps the sound quality of the monitored signal pure and intelligible—enabling the performer to hear like never before, even at lower volume levels. To further ensure pristine audio quality, this versatile monitoring system uses a PLL design that effectively eliminates annoying static without the need for a squelch control. Operating the EM900 couldn't be more intuitive. With 960 automatic scanning channels, finding an open frequency is never a challenge, even in RF (radio frequency) rich environments. Similarly, the EM900's transmitter features balanced XLR inputs for accommodating noise and hum free input signals—further ensuring superior audio performance. With clear, easy to read LCD displays on both the transmitter and beltpack receiver — including a low battery indicator — working with Carvin's EM900 is a pleasure. The new EM901 receiver offers a personal pan control that facilitates the mix of two independent signals — either mono or stereo. As a result, each performer can adjust a 2 channel mix in their ears. The EM900 In-Ear Personal Monitor System includes flat response earbuds with three sizes of soft earbud tips to ensure the proper fit and comfort. The system uses braided cable and clear driver enclosures for reduced audience visibility. Combined with rugged aluminum enclosures — not plastic like some competing systems — for both the transmitter and beltpack receiver, Carvin's EM900 In-Ear Personal Monitor System is built to provide years of dependable service. - Hear yourself like never before - especially at lower volumes - More selectable frequencies, 960 automatic scanning channels - Articulate sound from the 20Hz to 20k Hz frequency response - Built in dynamic limiter keeps the sound pure and intelligible - The EM901 receiver offers a personal "Pan" control, allowing the mix of two independent signals, mono, or stereo - each performer can adjust a 2 channel mix in their ears! - LCD display on both the transmitter and receiver – including low battery - PLL (phase lock loop) eliminates annoying static - no squelch control required - Flat response earbuds with 3 sizes of soft earbud tips.
