Preamplificator Multicanal Classe Sigma SSP

The Sigma SSP is a 7.1 channel preamp/processor optimized for stereo but including HDMI switching, multichannel processing and bass management. Its wide variety of input connectors includes asynchronous USB and Ethernet for streaming, augmented by coax and optical; balanced and single-ended analog inputs plus an optional phono stage show how versatile this preamp/processor is despite its compact size. A host of performance-oriented features including digital domain tone/tilt control, and nine-band per channel parametric EQ ensure the best performance with each recording in every room.USB audio up to 24-bit/192 kHz USB (Host) charging capability 2 Amps AirPlay supported formats AAC (8 to 320 kbps) Protected AAC (from iTunes Store), HE-AAC, MP3 (8 to 320 kbps), MP3 VBR, Audible (formats 2, 3, 4) Audible Enhanced Audio (AAX, and AAX+), Apple Lossless, AIFF, and WAV DLNA supported formats Apple Lossless (ALAC), mp3, FLAC, WAV, Ogg Vorbis, WMA, AAC Frequency response 8 Hz - 200 kHz1 dB, stereo digital bypass 8 Hz - 20 kHz0.5 dB, all other sources Channel Matching (Left to Right) better than 0.05 dB Distortion (THD+noise) 0.0005%, digital source/bypassed analog source .002%, processed analog source Maximum input level (single-ended) 2 Vrms (DSP), 4.5Vrms (bypass) Maximum input level (balanced) 4 Vrms (DSP), 9 Vrms (bypass) Maximum output level (single-ended) 9 Vrms Maximum output level (balanced) 18 Vrms Gain Range -93 dB to +14 dB Input impedance (single-ended) 100 k (single-ended) Input impedance (balanced) 50 k (Balanced) Output impedance (single-ended) 100 Output impedance (balanced) 300 Signal-to-noise ratio (ref. 4Vrms input, unweighted) 104 dB, bypassed analog source 101 dB, processed analog source (re. full-scale input, unweighted) 105 dB, digital source Channel separation better than 100 dB Channel matching (left to right) 0.05 dB Crosstalk (any input to any output) better than -130 dB @ 1 kHzRated power consumption 35 WMains voltage 100-240 V, 50/60 Hz Overall dimensions 17.0 (433mm) Depth (excluding connectors): 14.57 (370mm) Height: 3.75 (95mm) Net weight 18 lb (8.21 kg)Shipping weight 25 lb (11.34 kg) Made for iPod touch (5th generation)iPod nano (7th generation) iPod touch (4th generation)iPod nano (6th generation) iPod touch (3rd generation) iPod nano (5th generation) iPod touch (2nd generation)iPod nano (4th generation) iPod touch (1st generation)iPod nano (3rd generation) Made for iPhone 5S iPhone 3GS iPhone 5iPhone 3G iPhone 4SiPhone iPhone 4 Made for iPad mini (with Retina display) iPad (3rd generation) iPad AiriPad 2 iPad (4th generation)iPad iPad mini Airplay AirPlay works with iPhone, iPod, and iPod touch with iOS 4.3.3 or later, Mac with OS X Mountain Lion, and Mac and PC with iTunes 10.2.2 or later.
