on the cable. Never touch the power cable when your hands are wet as this could cause an electric shock. Do not
tie a knot in the cable. The power cable should be placed such that it is not likely to be stepped on. A damaged
power cable can cause a fire or give you an electrical shock. Checkthe power cord periodicaly, if you ever find that
it is damaged, replace it before using the unit again. Contact your retailer for a replacement.

The voltage of the available power supply differs according to country or region. Be sure that the power supply
voltage of the area where this unit is to be used meets the required written on the unit.

The lightning flash symbol inside a triangle is to alert the user to the presence high voltage within the
unit’s enclosure that may be of sufficient power to constitute a risk of electrical shock to persons.

Caution: to prevent the risk of electric shock, do not attempt to open the unit. No user-serviceable parts
inside. Refer all servicing to qualified service personnel.

The exclamation mark inside a triangle is intended to alert the user to the presence of important operating
and maintenance instructions in the literature accompanying the appliance.

Select the installation location of your unit carefully. Avoid placing it in direct sunlight or locations subject to
vibration and excessive dust. Do not use the unit where there are extremes in temperature (below 41ºF / 5ºC or
exceeding 95ºF / 35ºC).

Unpacking and safety Please unpack your new product carefully. Your new product should reach you in perfect
condition. Please check that no damage has occurred during transit. If any damage is found, do not operate your

Unpacking

Warning: After unpacking, and before plugging the AC cord in the wall outlet, check whether the AC mains voltage

and frequency is the same as this product (AC220-250V~ 50Hz). If the specified voltage or your AC plug should
not match the local conditions, do NOT plug the AC cord into the wall outlet and contact you dealer immediately.

Back Panel

1. Mains input and fuse holder. Use the supplied power lead to connect the unit to AC mains. Make sure

voltage and frequency stated on the unit comply with your local AC supply. The fuse can be accessed by the
small drawer in the AC inlet. To change the fuse, unplug the AC cord first, pull out the fuse drawer and
replace the fuse ONLY with a fuse of SAME voltage and rating. If the fuse blows again after replacement,
please contact your nearest retailer to get the unit checked out.

2. Power switch. Switches the unit on and off. Make sure to switch the unit off when not in use.

3. Balanced output. This is a balanced stereo output carrying the main output signal controlled by (32).

4. Main stereo output. This is an unbalanced output carrying the same signal as output (3).

5. Subwoofer output. This is a balanced mono output for connecting an amplifier driving a subwoofer system.

Please note that the subwoofer output runs in parallel to the main output, hence while the subwoofer upper
frequency limit can be adjusted by means of control (6), no lower frequency limit is introduced to the main
output (3).

6. Crossover frequency adjustment of internal active crossover. Together with the level control (7), this

allows to set the upper frequency limit of the subwoofer output (5). Choosing an appropriate crossover
frequency will avoid unpleasant interference effects with your main program speakers. Check your subwoofer
system specification to determine a suitable frequency.

7. Level control for subwoofer output (5).

8. Booth stereo output. This is an unbalanced output carrying the booth signal controlled by (33). This output

can be used for a 2nd zone which needs independent volume control, such as the DJ booth or the seating
area of a club.

9. Record output. This is an unbalanced stereo output carrying the same signal as the main output (3/4), but

not influenced by the main volume control (32). This is normally used for recording the output to an external
tape, CD or memory device.

10. FX Loop. These two ¼’’ jack (6.35mm) connectors allow you to add a stereo effects processor to the master

signal path. They interact with the top panel controls (41, 42, 43, 44 ). Please note that this effects loop is
NOT an insert path, but a parallel effects path, meaning effects like filters (which are of serial nature) are not
as effectively processed by the effects loop as effect like reverb or delay (which are of parallel nature).

11. Line inputs. These RCA connectors provide inputs for line-level signals to the assigned channels.

12. Phono Inputs. Depending on the position of the selector switches (13), these RCA connectors provide the

following inputs: (A) Position “PHONO”: input for phono-level signals to the assigned channels, featuring the
necessary RIAA equalization. (B) Position “LINE”: input for line-level signals to the assigned channels. Note
please ensure the correct line / phone level is selected before connection as failure to do so may cause
damage to the unit.

13. PHONO/LINE selector switches for PHONO inputs. These switches change the sensitivity of the PHONO

inputs between PHONO (RIAA equalized) and LINE level.

14. Microphone inputs for MIC1. This is a balanced ¼” jack (6.35mm) connector without phantom power

provision, hence only suitable for dynamic microphones. Please note that this connector is in parallel to the
top-panel mounted balanced Combo (XLR + ¼” jack) 6.35mm connector (18).

15. Microphone inputs for MIC2. Same as (14) but for microphone 2.
