The GUSTARD P26 Fully Balanced Pre Amplifier Class A 2*LM49860 HIFI Preamp is a preamplifier that has a class A fully balanced design with the left and right channels divided into regions for good left and right separation. It has a native full balance architecture, from input to volume control to amplifier circuit, without any conversion, complete four-way architecture. The preamp uses an op amp + discrete hybrid architecture, which ensures circuit consistency and no lack of adjustability. Two in-line LM49860 dual op amps can be replaced to increase playability. It also has a discrete diamond-shaped differential output stage to easily drive various back-end loads. The volume of matrix relay is used to effectively ensure that the volume of 4 channels is consistent and unbiased¹. It has adjustable input stage gain and output stage gain, easy to match different front and rear ends¹. The preamp also has a large OLED display + full-featured remote control operation, user-friendly design.
The GUSTARD P26 Fully Balanced Pre Amplifier Class A 2*LM49860 HIFI Preamp has analog input (3 groups): RCA: input impedance 47k input sensitivity 2 ~ 10V rms XLR1 & XLR 2: input impedance 47k maximum input amplitude + 28dBu (19V rms) @ IGAIN = 0dB.
