4 Connection
To avoid loud switching noise, set all output controls to minimum
before connecting or disconnecting an audio source .
4.1 Microphones
Important: Before connecting a microphone, check the phantom
power setting of the relevant input and change it if necessary (chapter
5.1). Phantom power may damage microphones with unbalanced
output signals. Only activate the phantom power when a microphone
requires phantom power.
Connect microphones with XLR plugs to the input jacks INPUT (1,
2) . A high-pass filter can be activated for channel 2 / R (chapter 5 .1) .
4.2 Instruments, audio sources with line level
Connect instruments or other audio sources with line signal level (e . g .
CD/MP3 player) with 6 .3 mm plugs to the input jacks INPUT (1, 2) . The
jacks are balanced; however, unbalanced audio sources can also be
connected via 2-pole 6 .3 mm plugs . When connecting an instrument,
the input for channel 1/ L can be set to high impedance (chapter 5 .1) .
4.3 Active speakers, amplifier, headphones
To monitor the audio signals via speakers, connect the outputs MAIN
OUTPUT (15) to the inputs of active speakers or to the input jacks
of an amplifier . The outputs are electronically balanced, but they can
also be connected in an unbalanced way (with 2-pole 6 .3 mm plugs) .
Connect stereo headphones to the jack
10
(13) .
4.4 Computer
Connect a computer to the port
port, BEE can also be supplied with power via this port . To do this, set
the switch POWER SOURCE (17) to the right .
If the computer only has Type-A ports, it can be connected via
the adapter cable provided . In this case, an additional power supply
is required (chapter 4 .5); the computer connection will not be able
to supply sufficient power .
4.5 Alternative power supply
If it is not possible to supply the interface with power via the computer,
connect a 5 V DC power supply with a current rating of 1250 mA to the
port USB POWER (16) . Set the switch POWER SOURCE (17) to the left .
5 Operation
To make sure that the initial volume is not too high, set the controls
MAIN (11) and PHONES (12) to minimum before first operation . After
connection to a computer / power supply, the POWER LED (14) will
light up .
5.1 Adjusting the inputs
To avoid loud switching noise, always set all output controls to mini-
mum before using a switch (3, 5, 20) .
1) HI-Z (3) – to set the input of channel 1 to high impedance (e . g . to
directly connect an electric guitar)
2) LOW CUT (5) – to activate a high-pass filter in channel 2, e . g . to
suppress impact sound
3) +48 V PHANTOM POWER (20) – to activate the phantom power
for microphones; please note the information in chapter 4.1!
