b.Line Output ports:
RCA single-ended output: Stereo line output (R+, L+ and ground). Maximum
output is 2.5Vrms; reduce volume in PRE mode if distortion occurs.
XLR3 balanced output: Balanced line output (R+, R-, L+, L-), suitable for active
speakers or amplifiers.
(2)Knob Functions:
a.Power on/off Selector Switch: Controls power on/off. Remote wake-up is d
isabled when the knob is in the off position.
b.Analog Output Selector Switch: Switch output PO+PRE, PO, PRE and LO
PO+PRE: Simultaneous headphone and line output, with volume and gain
adjustments affecting both.
PO: Only headphone outputs are active (6.35mm, 4.4mm, XLR4).
PRE: Only line outputs are active (RCA, XLR3), with adjustable volume (unaffected
by gain).
LO: Fixed maximum volume line output (volume and gain controls disabled). Ensure
connected devices are set to appropriate levels to avoid loud noises.
c.Gain Switch: Five levels—L (Low), M (Medium), H (High), SH (Super High),
UH (Ultra High). Gain can be achieved through software gain, which controls
the internal volume output level via software, or hardware gain, which change
s the amplification factor of the hardware circuit.
