FLASH8P INSTRUCTIONS (FIG. 4 / 5 / 6)
15. INPUT (SPEAKON)
External amplifier power input: this is the connector where you plug in the power cable coming from your power
amplifier or powered mixer. The powered signal is filtered by an internal passive crossover for the LF woofer and HF
compression driver. The INPUT speakon has this pin connection:
PIN1+: positive power signal (usually red wire)
PIN1-: negative power signal (usually black wire)
16. LINK (SPEAKON)
Output of the power signal to be sent to another loudspeaker. INPUT and LINK connectors are in parallel connection.
17. PRODUCT LABEL
In this label are written the most important information about the loudspeaker: model, power handling, impedance
serial number.
PROTECTION
A protection circuit is built in to protect the high-frequency compression driver from excessive power. When the power
to the HF driver approaches the maximum, the power delivered to the driver is momentarily interrupted.
NOTE: The protection circuit is designed to protect the HF driver under reasonable and sensible conditions. Should you
choose to ignore the warning signs (i.e., frequent clip LED indications, excessive distortion), you can still damage the
speakers by overdriving them past their recommended amplifier power-handling ratings, or past the point of amplifier
clipping. Such damage is beyond the scope of the warranty.
CHOOSE THE AMPLIFIER POWER
We give you two power-handling numbers: continuous and peak. So these data suggest you can use any amplifier with
a power capability equal or less the power-handling, but this rule is valid only if the amplifier never clip any time.
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 amplifier 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 specified impedance (typically 4 or 8 ohms):
• To obtain the best result using FLASH8P / 8 ohm we suggest the use of PROEL HPX-900 amplifier for a standard
stereo configuration.
IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the amplifier) 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.
