is fed to the internal amplifi er at the same level at which it arrives on input).
6. MIDFIELD / NEARFIELD preset switch
This switch allows to select two different EQ presets optimized for two different applications: NEARFIELD is for the use
as a PC or DESKTOP speaker, MIDFIELD is for the use a a musician MONITOR, as an INSTALLATION speaker or as a
PORTABLE DJ or LIVE system (with SW110A sub-woofer).
7. SIGN / LIMIT indicator
GREEN LED illuminates to indicate the presence of the signal at the amplifi er input.
RED LED illuminates when the internal amplifi er's output is limited. When this LED fl ashes reduce the input signal level.
8. ON indicator
GREEN LED: when lighted indicates amplifi er has been turned on and AC power is available.
9. POWER switch
Speaker is "ON" when the switch is in the "I" position, use this switch to set the speaker power to ON or OFF.
NOTE: When you shut down your equipment, turn off the speaker fi rst.When powering up, turn on the speaker last.
10. AC~ socket
Here’s where you plug in your speaker’s mains supply cord. You should always use the mains cord supplied with the
speaker. Be sure your speaker is turned off before you plug in the cord.
11. LINE VOLTAGE selector
This selector set the AC voltage line of your country (usually it is set by factory and isn't necessary to change). The 120V
setting is for mains line in the range of 105-120V~ and 240V setting is for mains line in the range of 210-240V~.
WARNING an incorrect setting of AC LINE VOLTAGE could damage seriuosly the internal amplifi er!
12. INPUT push terminals (PASSIVE version)
External amplifi er power input: this is the connector where you plug in the power cable coming from your power amplifi er
or powered mixer. The powered signal is fi ltered by an internal passive crossover for the LF woofer and HF tweeter. The
INPUT has this pin connection:
RED + : positive power signal (usually red wire)
BLACK - : negative power signal (usually black wire)
Following the same polarity for the whole audio system is very important for obtaining an optimal acoustical result.
13. SNBK / SNWH accessories fi xings (PASSIVE version)
Remove these screws to install the versatile plastic bracket with 2-axis rotation. SNBK (black fi nish) and SNWH (white
fi nish) are available as optional accessories.
CHOOSE THE AMPLIFIER POWER (PASSIVE version)
We give you two power-handling numbers: rms (continuous) and peak. So these data suggest you can use any amplifi er
with a power capability equal or less the power-handling, but this rule is valid only if the amplifi er never clips.
Preventing loudspeaker damage caused by clipping, that is likely the number one cause of damage, and assuming you
want to use the full capability of the loudspeaker, we recommend the use of an amplifi er with a built-in limiter to prevent
clipping. In this case the rated power capability must be the same continuous power rating of the loudspeaker into the
same specifi ed impedance (tipically 4 or 8 ohms):
To obtain the best result using FLASH5 PASSIVE loudspeakers we suggest the use of amplifi ers as indicated on the
following table:
AMP rms rating power
for 1 channel
nominal impedance
for 1 channel
Number of FLASH5 (16 ohm)
speakers connected in parallel
50-100W into 8 ohm 16 ohm 1
100-150W into 8 ohm 8 ohm 2
150-250W into 4 ohm 5.4 ohm 3
200-300W into 4 ohm 4 ohm 4
IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the amplifi er) reaches its
maximum level. Proper operation of a sound system includes being aware of the types of audio signals being reproduced,
controlling the output levels accordingly, and operating all the devices in the system so that no clipping occurs within
the signal chain.
