Due to the scarcity of components, the two Wima square capacitors come from older devices. 2. The operating voltage of E2 is 15V DC (≥ 3A). A voltage lower or higher than this value can lead to poor performance or damage. 3. The three headphone jacks cannot be used simultaneously. Please select a socket. 4. Stereo RCA and headphone outputs can work simultaneously, and the volume/gain of both outputs is controlled simultaneously. 5. The E2 uses an operational amplifier NE5532 and an operational amplifier 49720. Only the 49720 op-amp is plug-in and can be replaced with dual op amps such as 2604/2134/muses02, etc. Settings Brand: Douk Audio Model: E2 Audio input: 2 groups of stereo RCA Audio output: RCA stereo/XLR 4 pin and 6.35mm jack Frequency response: 20Hz-20kHz (±0.5dB) THD+B: 0.02% SNR: ≥ 110dB Suitable headphone impedance: 16-600Ω Headphone Output Power: Low Gain (G): 0.55W, High Gain (H): 2W RCA Output Level: Low Gain (G): 4.3V, High Gain (H): 8.4V Input Sensitivity: 2V Working Voltage: DC 15V/≥3A Dimensions (L x W x H): 95 x 92 x 50 mm Package dimensions (L x W x H): 280 x 230 x 110 mm Net weight: 1.2kg Package weight: 1.6 kg What you get: 1 x E2 Headphone Amplifier 2 x ECF801 Tubes 1 x 15V DC Power Adapter 1 x 6.35mm Jack to 3.5mm Jack Adapter 1 x User Manual Review: Top Vorverstärker für den Preis - Für den Preis ein sehr guter Verstärker mit einer super Verarbeitung.
