INPUTS:
- LINE 1 – 4: Standard line inputs
- LINE 5 HT: Home theater bypass. WARNING! When
this input is selected the volume
control is inactive, the full scale input
level is coupled to the power amplifier
section! Do not connect any fixed line
level signal to this connector, only a
volume controlled signal is accepted!
- MM phono: Moving magnet phono cartridge input
- BT: Bluetooth wireless input. Ready for
connection in any position of the input
selector.
Optional DAC Card:
USB with DSD
Coaxial S/PDIF
Optical S/PDIF
OUTPUTS:
- PRE OUT: Volume controlled output
- LINE OUT: Fixed line level output
- SPEAKERS: High level output for loudspeakers,
impedance 4 –8 Ohms
- HEADPHONES: 6.35mm stereo output for any dynamic
headphones. When headphones are
connected, the speaker outputs are
muted.
PLACEMENT:
Any rigid surface can be sufficient for placing your Lagrange. Please
consider the weight of the amplifier. It is best to place it
on a sturdy piece of furniture with stable footing and
the least possible movement.
VENTILATION:
Always allow adequate ventilation and airflow around the unit. Do
not place it directly on carpet, soft fabric, etc. that can
block the ventilation holes.
HEAT DISSIPATION:
The Lagrange has a Class A headphone amplifier inside, which
generates some amount of heat at idle. This is normal.
CONNECTIONS:
It is best to do any cable connection when the amplifier is switched
off. Take extra care when connecting loudspeakers! Do
not touch any of the poles to ground or to each other!
REMOTE CONTROL:
Volume up (+) and down (-), input up ( ) and down ( ), and mute
functions are available. When muted, the volume knob
LED is off.
Input selection cycle (*with optional DAC card):
L1 L2 L3 L4 MM BT (USB* COAX* OPT*) L5HT L1
DISPLAY:
The Lagrange has an auto-off OLED display. To see the actual input,
push the up or down button on the remote shortly, or
turn the input selector one click to left or right. Until the
display is on, the input selection works as usual.
