IMG STAGELINE Bee USB 2-Kanal Recording Interface Instruction Manual
USB Recording Interface
These instructions are intended for users with basic knowledge of audio technology and computing. Please read the instructions carefully prior to operation and keep them for later reference.
Applications
The BEE audio interface is used for audio recording on a computer. It is
recognised by the computer as an external sound card. It features two analogue
inputs to record audio signals from microphones, instruments and other audio
sources on a computer in high quality. Two analogue outputs allow reproduction
of audio signals from the computer, e. g. via active speakers. These signals
can also be monitored via a headphone output. The device also offers phantom
power that can be activated separately for both inputs, a switchable high-pass
filter for one input and an input that can be switched to high impedance for
instruments.
Power is supplied via a USB-C port on the computer or via a 5 V power source
additionally connected, e. g. a power supply unit. A USB adapter cable with
Type-A plug is provided.

Overview
- Combined input jack for channel 1 to connect a microphone (XLR) or an audio source with line signal level (6.3 mm jack) with switch HI-Z for an instrument
- Combined input jack for channel 2 to connect a microphone (XLR) or an audio source with line signal level (6.3 mm jack)
- Switch HI-Z: When the switch is engaged, the input of channel 1 is of high impedance.
- Phantom power LED +48V for channels 1 and 2 respectively
- Switch LOW CUT of the high-pass filter for channel 2
- Control GAIN of the input gain for channels 1 and 2 respectively
- LED PEAK to indicate the maximum level reached for channels 1 and 2 respectively
- Switch LOOP BACK; when the switch is engaged, the audio signal coming from the computer will be routed back to the computer along with the signals of the inputs
- Switch DIRECT; when the switch is engaged, the signal of the inputs will be routed to the outputs MAIN OUTPUT (15) and PHONES (13)
- Switch STEREO [for DIRECT mode (9) only]: when the switch is engaged, the input signals will be sent separately to the right and left outputs; when the switch is disengaged, both input signals will be sent to both outputs
- Volume control MAIN for the outputs MAIN OUTPUT (15)
- Volume control PHONES for the headphone output (13)
- 6.3 mm jack to connect stereo headphones
- POWER LED
- Outputs MAIN OUTPUT (6.3 mm jacks), e. g. to connect active speakers
- USB POWER (Type-C) port to connect a 5V DC power supply, e. g. a power supply unit
- Switch POWER SOURCE to select the port for power supply
- USB data port for connection to a computer; can also be used for power supply when it is connected to a Type-C port
- Opening in the housing to attach an anti-theft device
- Switch +48V PHANTOM POWER to activate the phantom power (position ON) each for the XLR contacts of the input jacks of channel 1 (1) and channel 2 (2)

Important Notes
This product corresponds to all relevant directives of the EU and is therefore marked with .
The product corresponds to the relevant UK legislation and is therefore marked with UKCA.
- The product is suitable for indoor use only. Protect it against dripping water, splash water and high air humidity. The admissible ambient temperature range is 0–40°C.
- For cleaning only use a dry, soft cloth; never use water or chemicals.
- No guarantee claims for the product and no liability for any resulting personal damage or material damage will be accepted if the product is not correctly used or not expertly repaired.
If the product is to be put out of operation definitively, dispose of the product in accordance with local regulations.
Connection
To avoid loud switching noise, set all output controls to minimum before connecting or disconnecting an audio source.
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).
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).
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 (13)
Computer
Connect a computer to the port (18). If the computer has a Type-C 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.
Alternative power supply
If it is not possible to supply the interface with power via the computer,
connect a 5V DC power supply with a current rating of 1250mA to the port USB
POWER (16). Set the switch POWER SOURCE (17) to the left.
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
Adjusting the inputs
To avoid loud switching noise, always set all output controls to minimum
before using a switch (3, 5, 20)
-
HI-Z (3) – to set the input of channel 1 to high impedance (e. g. to directly connect an electric guitar)
-
LOW CUT (5) – to activate a high-pass filter in channel 2, e. g. to suppress impact sound
-
+48V PHANTOM POWER (20) – to activate the phantom power for microphones; please note the information in chapter 4.1!
When phantom power has been activated, the LED +48V (4) underneath the corresponding input jack will light up. -
Use the GAIN controls (6) to turn up the input gain so that the LEDs PEAK (7) only light up briefly during level peaks.
Adjusting the outputs
-
Use the control MAIN (11) to adjust the output level.
-
Use the control PHONES (12) to adjust the headphone volume.
CAUTION
Never adjust the headphones to a very high volume. Permanent high volumes may damage your hearing! -
The switch DIRECT (9) can be used to directly monitor the signals of the inputs without the latency caused by the computer. The position of the switch STEREO (10) determines whether the input signals are reproduced as a mono signal (switch disengaged) or as a stereo signal (switch engaged).
-
The switch LOOP BACK (8) can be used to route the audio signal coming from the computer back to the computer along with the signals of the inputs (mono mix).
Note: If feedback occurs, deactivate the monitoring function or feed- through function in the recording software.
