4/5 XO2.4 Mk2
Remark: Use this switch with care. This switch is most effective on the low frequencies: switch the
inverter on/off while listening to the music. Choose the position with the most bass reproduction
7. HIGH Output: controls the HIGH frequency output level from -
∞ to +6dB. When you work in Mono
mode, you can only use the Channel 2 knob.
8. HIGH Phase Invert Switch: Switch for inversing the polarity on the HIGH output. A LED indicates your
selection. When you work in Mono mode, you can only use the switch on Channel 2.
Remark:
In most cases you don’t need to use this switch. When the setting is wrong, it can bring you
more bad then good
9. MONO/STEREO LED: This LED indicates if you are working in MONO or STEREO Mode:
•
MONO Mode: Both channels work together to obtain a 3-way mode crossover
•
STEREO Mode: Both channels work independently to obtain an 2x2-way crossover
10. Power Switch: Switch for turning the unit ON/OFF
FUNCTIONS (rear)
11. Mains Input: with IEC socket and integrated fuse holder, connect the supplied mains cable here
12. Ground Lift Switch: In some cases nasty hum noises can occur due to ground loops in your setup.
Setting the Ground Lift Switch to the position “lift” breaks the ground loop between the EC102/XO-2.4
and the chassis grounds of various other components in your setup. As a result the hum noises will
disappear.
13. XLR Inputs: Balanced inputs using XLR cables. When you work in Mono Mode, you only have to
connect an XLR cable on Channel one
14. LOW/MID XLR Output: Balanced outputs using XLR cables:
•
In Stereo Mode: When you work in Normal mode ( see number 17 for more information
), you have to connect an XLR cable to Channels 1 and 2. When you work in Summed
mode, you only have to connect an XLR cable to Channel 1.
•
In Mono Mode: Channel 1 operates the LOW output.
Channel 2 operates the MID output.
15. HIGH XLR Output: Balanced outputs using XLR cables:
•
In Stereo Mode: You have to connect an XLR cable to both channels
•
In Mono Mode: Only Channel 2 is used
16. MONO/STEREO Switch: With this switch, you can choose between MONO 3-way or STEREO 2x2-way
Mode
17. LF SUM Switch: With this switch, you can choose if you want your LOW frequencies in normal mode ( 2
outputs ), or summed ( uses only channel 1 output ) ( see number 14 for more information ). In summed
mode the low frequency from C
hannels 1&2 are put together so you don’t have to use a splitter cable in
case you have only 1 subwoofer.
18. Crossover Frequency Switch: With this switch, you can choose between x1/x10 frequency range ( see
number 4 for more information )
19. AC Voltage Selector: Before to connect the unit to the mains: always check if the switch is set to the
voltage that is used in your area. (115 VAC/60Hz or 230 VAC/50Hz). Using the wrong setting can
damage the unit !
