The SR4003 is a mid-line AV receiver offered by Marantz.  This mid-priced receiver uses audiofile grade parts to give the listener a full A/V experience, without draining their bank account.  With seven 80 watt channels, each with their own discrete amplifer stages, the SR4003 has plenty of power for its price.  The SR4003 uses a Cirrus Logic processor which handles all of todays most popular digital audio formats, and features Marantz Room Acoustic Calibration (MRAC) to analyze the room acoustics and adjust its settings accordingly. Audio inputs and outputs are plentiful with eight analog stereo ins, three optical ins and two coaxial ins along with three analog stereo and one optical out. For video, there are three HDMI inputs, which can be upgraded to eight with the Marantz's VS3002.  Other video-ins include three component, five s-video and five composite inputs.  Two S-video, two composite, one HDMI and one component video out complete the massive number of connections available on this receiver.  The backlit remote can learn commands to control other electronics in your system.  Other features include a "locking" front panel to preserve your settings and reduced depth chassy made from vibration absorbing glass fiber-reinforced resin.
