Dual—mono design, the left and right channels have no electrical connection
Full DC coupled line
Sound characteristics: high resolution, straight curve, good three-band extension, ultra-low distortion, ultra-low noise
Design materials
Large all-aluminum chassis 430*90*270mm
ALPS27 large remote control potentiometer can adjust the volume manually or remotely
N transformer version: Uses two 30W imported transformers, one for each left and right channel
B transformer version: Uses two 50W imported transformers, one for each left and right channel
4 new audiophile-grade OPA828s are used as main amplifiers, 6 OPA604APs are used as balanced input and output, and 2 NE5534 are used as AUX buffers.
It has complete protection and has the functions of delayed start-up and instantaneous shutdown, avoiding the impact of power on and off.
4 inputs: 3 sets of single-ended inputs, 1 set of balanced inputs
The AUX input is buffered, which makes the sound very vivid and increases the density of the sound. I recommend you give it a try; the AUX input is designed with a buffer circuit, which mainly increases the input resistance, reduces the output resistance, improves circuit dynamics, reduces noise, and improves circuit stability. performance; the output resistance of some audio sources is too large and cannot be used with load, and buffering can also solve the problem; for specific sound effects, you can compare it with unbuffered input.
2 outputs: 1 set of RCA single-ended output, 1 set of XLR balanced output, RCA and balanced output at the same time, can be connected to 2 channels of post-stage balanced input and output terminals at the same time
Chassis color: available in silver or gold, working voltage available as AC115v or AC230v
