Using the product
1. Insert a 9 V battery into the device or connect a suitable power adapter that pro-
vides 9 V (not supplied) to the 9 V connector (negative pole = internal connector
). When the DI output is used with a device that provides phantom
power, the supply voltage can also be provided via the phantom power supply.
Then the D.I. switch
must
be in the GND position. Turn on the unit with the ON /
OFF switch, the ON / OFF LED will turn red.
2. Connect an electric bass to the INPUT jack using a shielded 1/4" jack cable. Watch
the CLIP LED while playing. If it often turns red, turn the GAIN control counter-
clockwise. If the LED is still red, the instrument's output level is too high. Then set
the INPUT switch to the -10 dB position.
3. Connect an amplifier to the OUTPUT socket. You can connect headphones to
the PHONES socket. The DI signal for feeding into a mixing console is present at
the 48 V D.I. OUT output. To feed the dry input signal to other devices, connect
them to the THRU socket.
4. Use the EQ to adjust your desired sound. The FREQ control allows you to adjust
the centre frequency of the mid control between 150 Hz and 8 kHz. The BLEND
control adjusts the ratio between the dry signal (left stop) and the EQ-pro-
cessed signal (right stop).
5. To activate the compressor function, press the COMP. switch, the COMP. LED will
turn red. Use the COMP. control to set the compression ratio. The THRESHOLD
control determines the level above which the signal will be processed by the
compressor.
