Input power supply: 19V DC (Max. 24V) Output power @ THD 1% : 18W RMS into 8Ω 35W RMS into 4Ω Frequency response: 11Hz~50kHz ±3dB THD: 0.05% @ 1W Input sensitivity: 1.1v p-p Voltage gain: 32dB Noise output voltage: 200µV (unweighted, input terminal shorted) Power input jack: 2.5mm DC plug Audio input terminals: 2 x RCA jacks Speaker output jacks: 4 x banana jacks Dimension: 120mm x 155mm x 50mm (W x D x H)

• This helps to produce a water clear sound quality.
• Class AB superb sound quality No switching noise as class D / T amplifier Tolerates large ranges of speaker's impedance 2 x 35W adequate output power (@19V dc) No needs for output filters to ensure pure sound
• SK‑240B is a compact, light weight and high performance audio power amplifier which can deliver up to 40W RMS power per channel into 4Ω speakers when using a 20V external power supply unit. The amplifier is optimized to use switching power supply for the best effect. A notebook computer power supply unit is a commonly available well suited choice for this purpose. An accurately calculated filtering circuit and a pair of huge capacity reserviors ensure the purity of the power source.
