PVDD_X = 40 V, GVDD = 12 V, audio frequency = 1 kHz, AES17 measurement filter, F PWM = 384 kHz, case temperature = 75°C. Audio performance is recorded as a chipset, using TAS5086 PWM processor with an effective modulation index limit of 97%. All performance is in accordance with the foregoing specifications and recommended operating conditions unless otherwise specified. PARAMETER CONDITIONS MIN TYP MAX UNIT RL = 6 Ω, 10% THD, clipped input signal 30 RL = 8 Ω, 10% THD, clipped input signal 25 PO,sat Power output per satellite channel W RL = 6 Ω, 0 dBFS, unclipped input signal 25 RL = 8 Ω, 0 dBFS, unclipped input signal 20 RL = 3 Ω, 10% THD, clipped input signal 60 RL = 4 Ω, 10% THD, clipped input signal 52 PO,sub Power output, subwoofer W RL = 3 Ω, 0 dBFS, unclipped input signal 50 RL = 4 Ω, 0 dBFS, unclipped input signal 40 RL = 6 Ω, PO = 25 W 0.3% Total harmonic distortion + noise, satellite RL = 6 Ω, 1 W 0.03% THD + N RL = 3 Ω, PO = 50 W 0.5% Total harmonic distortion + noise, subwoofer RL = 3 Ω, 1 W 0.03% Output integrated noise, satellite A-weighted 55 Vn µV Output integrated noise, subwoofer A-weighted 60 SNR System signal-to-noise ratio A-weighted 105 dB DNR Dynamic range(1) A-weighted, –60 dBFs input signal 105 dB PO = 0 W, all channels running 5.1 mode(2) 8 W Power dissipation due to idle losses Pidle (IPVDDX) PO = 0 W, 2.1 mode 4 W (1) SNR is calculated relative to 0-dBFS input level.
