Unit is a Return - Might have scuffs from shipping - Fully Tested - Repackaged to Ship AUDIOPHILE CLASS AB HOME THEATER AMP: A powerful and affordable 5-channel Class AB amplifier rated at 5x210 Watts (4 ohms), 145W (8 ohms), all channels driven.BALANCED XLR: For Ultra-Low Noise and RCA Inputs12V TRIGGER: Control for remote power on/off.INDIVIDUAL CHANNEL LED’s: displays the amp’s status - ON, Standby, or Protection mode.110 dB SNR: at rated power, 105dB at 1W, for exceptional dynamic range.The HTA5200 can easily achieve the reference cinema sound levels of 105dB from all channels. The HTA5200 is rated at 210 Watts per channel, all channels driven (not just one channel, as stated by most competitors) into 4Ohms. Used with typical speakers, this allows for a sound-pressure level of 112-115dB, 7-10dB more than required for reference sound levels. The additional dB’s means the amplifier is working well within its normal range, and this keeps the distortion low. (A good example of this is turning your TV up too much - it does not sound good. This is because the closer you get to full power the higher the distortion.) With this amplifier at 105dB, the distortion is below 0.01%.By choosing the best components, we can also achieve 110dB SNR at full power, this allows for a very wide dynamic range, allowing you to hear the softest and loudest sounds more clearly. This combination of performance specifications is hard to find from any amplifier, regardless of price. By choosing an OSD HTA amplifier, you have achieved the goal of great performance at an affordable price. 210 watts per channel into 4 ohms (10-30,000 Hz) at <1% THD with all 5 channels driven.145 watts per channel into 8 ohms (10-30,000 Hz) at <1% THD with all 5 channels driven.Specifications: All Channel Output:4 Ohms @1% THD - 210W8 Ohms @1% THD - 145W4 Ohms @0.1% THD - 180W8 Ohms @0.1% THD - 125WSingle Channel Output:4 Ohms @1% THD - 265W8 Ohms @1% THD - 180W4 Ohms @0.1% THD - 235WFrequency Response: 5Hz - 50KHz, +/- 3dBInput Sensitivity: 1VSignal to Noise:Rated Power: 110dB1W: 105dBClass ABAir Cooled12V TriggerIdle Current: 0.14 AmpsMax Current All Channels: 13.6 AmpsTransformer: 2 x ToroidalCapacitors: 4 x 10000uFPower Supply: 110/240VRack Mountable: YesWeight: 63 lbsDimensions: 6.3" x 17.1" x 16.57"8" 200W 2-Way HD Weather Resistant Outdoor Patio Speaker Pair (70V Optional) - White Features ---OPEN BOX - Item might come repackaged, but 100% working condition ---8" polypropylene woofer, 1" supernil soft dome tweeter ---Power Handling is up to 200 watts and frequency response of 37 Hz to 22 kHz ---All-Weather versatility with rigid, acoustically inert enclosure, silicone-sealed internal cabinetry and driver ---Unit Dimensions: 15.75 x 11 x 10 inches ---Optional 70-volt built-in selectable taps: 2.5W, 5W, 10W, 15W, 25W A customer favorite, the AP850 patio speakers serve up big, audiophile sound without the big audiophile price tag!
