4. Replacing the Fuse
• Only fit or replace a fuse when the device is unplugged from the mains.
• Replace a blown fuse with a fuse of the same type and rating (see "Technical Specifications"):
1. Unscrew the fuse holder at the back with an appropriate screwdriver.
2. Remove the old fuse and install a new one.
3. Replace the fuse holder and fasten it with the screwdriver.

5. Controls and Connections

1. LEVEL CONTROL: controls the level of the signal.
2. EQ ON/OFF switch + indicator: when the red LED is lit, the equaliser is activated, otherwise it is in bypass mode.
Use this switch to compare equalised and un-equalised signals.
3. SLIDE CONTROLS: There are 15 controls for each channel. In the middle position (0), there is no modification for
that frequency. To boost or cut a frequency, move the slide control upwards or downwards respectively.
4. VU METER: indicates the output level of the channels 1 and 2.
At the back of the device, you find the power switch, the power cord, the fuse holder and the input/output
connections. For each in- and output, 2 types of connections are available:
- 6.35mm jack: balanced and wired as tip=Hi(+), ring=Lo(-) and the sleeve is ground.
- XLR connector: balanced and wired as pin1=ground, pin2=Hi(+), pin3=Lo(-)
CAUTION: only 1 type can be used per input/output. Never connect both types for 1 input or output.

6. Cleaning and Maintenance

1. All screws should be tightened and free of corrosion.
2. The housing, mounting supports and the installation location should not be deformed, modified or tampered with.
3. Moving mechanic parts must not show any signs of wear and tear.
4. The electric power supply cables must not show any damage. Have a qualified technician maintain the device.
5. Disconnect the device from the mains prior to maintenance activities.
6. Wipe the device regularly with a moist, lint-free cloth. Do not use alcohol or solvents.
7. There are no user-serviceable parts apart from the fuse: refer to "Replacing the fuse".
8. Contact your dealer for spare parts if necessary.
