V. OPERATION INSTRUCTIONS
1. POWER SWITCH
After having connected the inputs to the corresponding appliances (CD player, Phono preamp,
tape, tuner...) and the outputs to the dedicated appliances (amplifiers, active crossovers…), the
VP100L preamplifier can be switched on using the power switch located on the rear panel of the
power supply chassis.
It is advised to put the VP100L on standby instead of switching off to fully and instantly benefit from
its maximum musical quality. However, if meant to keep away for a long time (as for holidays for
instance), or in the case of any storm risk, it is considered safe to switch the appliance off, with the
rest of the Hi-Fi elements.
2. OPERATIONS
Stand-By mode is accessible from the remote control. It allows reducing dramatically the energy
consumption of the appliance. Once awoken (disabling the stand-by mode), the preamplifier will
provide its optimum musical quality after only 15 minutes, whereas the first operation will require
more than 4 hours of warm-up (as will require any main switch-on) to reach this same level.
VP100L offers 8 inputs (4 single ended “RCA”, and 4 balanced “XLR”). At start-up, it initializes
itself to the RCA1 input and the -66 db volume level (max attenuation). Use the Volume knob (right
knob) or the remote control to adjust the volume. Use the Selector knob (left knob) to select other
inputs.
Mute function from remote control permits to lower instantly the volume to its minimum (being -90
dB). A new push on the Mute key will bring the volume level back to its previous state.
Display function from the remote control permits to switch the digital display on or off.
Set-up is accessed through a light push on the Volume knob. Using the Selector knob it allows to
tune some parameters at initial set-up of your preamplifier, such as the channel balance between
left & right and the output level of each input.
To adjust the channel balance, turn the Selector knob to Channel balance. The balance level
between left and right channels can be adjusted by turning the Volume knob. The inter-channels
balance is limited to 9dB maximum.
Level of the inputs, RCA1…….XLR8, can be adjusted limited to -10 dB. If the appliances
connected to the VP100L should have the same output level, then use the level of the appliance
with the lowest sensitivity as reference and adjust by lowering the output level of the other
appliances with the Volume knob until all have the same output level. Now the Vp100L can be
switched from one appliance input to the other with the same output level.
Push lightly on the Selector knob to exit the set-up program. All parameters are then stored within
the preamplifier.
