Meridian DSP5500HC DSP Centre-channel Loudspeaker USED NOT TESTED SOLD AS IS FOR PARTS OR REPAIRprobably will need new driver see picture 3 Meridian DSP5500HC The DSP5500HC is constructed with steel panels sandwiched between the rigid inner cabinet and the veneered outer panels on four sides. The two 200mm bass drivers are housed in separate internal enclosures. A third internal enclosure houses the tweeter and midrange. As a result the acoustic cabinet is extremely rigid, giving the benefits of extension, clarity and dynamic range unheard of in conventional centre channels. Meridian also included innovative DSP technology to compensate for boundary and corner use. This is a centre speaker that can be installed in almost any environment with confidence. The DSP5500HC has been designed to work coherently with the Meridian DSP5500, DSP6000 and DSP8000 loudspeakers. Technical Specification Performance: Frequency response in-room within 3dB from 35Hz to over 20kHz. Maximum output >111dB spl @ 1m on music material Noise less than 15dB spl. Overall distortion typically <0.02% at any frequency or level. Inputs: Two digital inputs to SPDIF standard; 32kHz–96kHz sampling rates at up to 24 bit; MHR support. (A future software update will enable support for 192kHz.) Construction: 3-way acoustic reflex system. 2 x 200mm long-throw bass drivers. 1 x 160mm polypropylene mid driver in separate enclosure. 1 x 25mm aluminium-dome tweeter, silver wire, short hornloaded with protective grille. Cabinet constructed from high-density MDF. Integral magnetic shielding and user-changeable real wood veneer acoustic damping side panels. FIFO memory buffer input for the lowest possible jitter from almost any source. Four precision 128x oversampling converters for bass, mid and tweeter signals. Analogue gain and filtering using proprietary Meridian Class-A discrete amplification. Digital and conversion electronics constructed using advanced surface-mount techniques and partitioned 6-layer printed-circuit boards. Four 75W power amplifiers, one for each of the drivers.
