POWER switch is in the
“
Off
”
position when initially connecting the unit to the mains.
Please take note: Merely switching the unit off does not mean that it is fully disconnected from the
mains. When not using the unit for prolonged periods of time, please unplug the unit
’
s power cord
from the power outlet.
2) Rear panel
Power is supplied via an IEC connector. The matching cable is provided with the unit.
FUSE COMPARTMENT / VOLTAGE SELECTION. Before connecting the unit to a power outlet,
please make sure that the selected voltage matches your local voltage. When replacing fuses,
please make sure that you always use fuses of the same type. Some units allow for switching
between 230 V und 120 V. Please note: when connecting a unit intended for the European market to
a 120 V power outlet, you must also replace the factory fuse with a higher-value fuse.
The DIRECT IN connects various input signals for each amp section, located on the rear. If a signal
is fed into this connector, both MAIN IN signals will be muted.
These are the MAIN OUT connectors of the equipment. The respective jacks and XLR connectors
are wired in parallel. Via these connectors, you can link as many headphone amps as desired to
allow for connection of additional headphones.
The MAIN IN connectors of the equipment come as balanced 1/4" TRS and XLR connectors.
The equipment features only 1/4" TRS connectors for MAIN INPUT 1 and MAIN INPUT 2.
4. GETTING STARTED
1) Using the MAIN IN connectors
Connect a program source with the MAIN IN connectors located on the rear, and connect your
headphones to an amp section of your choice. In the case of the equipment, MAIN IN controls 1 and
2 regulate the input level of two separate input signals.
2) Connecting multiple headphones
You can connect multiple headphones to an amp simultaneously, provided that the minimal output
load impedance of the amp does not fall below 8 Ohms. In the case of the equipment, the minimal
output load impedance is 100 Ohms per amp.
When connecting two headphones, individual headphones should not have impedance lower than
16 Ohms; when connecting three headphones, the impedance of individual headphones should not
fall below 200 Ohms.
