FLASH12P INSTRUCTIONS (FIG. 4 / 5 / 6)

15. INPUT (SPEAKON)

External amplier power input: this is the connector where you plug in the power cable coming from your power

amplier or powered mixer. The powered signal is ltered by an internal passive crossover for the LF woofer and HF

compression driver. The INPUT speakon has this pin connecon:

PIN1+: posive power signal (usually red wire)

PIN1-: negave 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 connecon.

17. PRODUCT LABEL

In this label are wrien the most important informaon about the loudspeaker: model, power handling, impedance

serial number.

PROTECTION

A protecon 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 protecon circuit is designed to protect the HF driver under reasonable and sensible condions. Should you

choose to ignore the warning signs (i.e., frequent clip LED indicaons, excessive distoron), you can sll damage the

speakers by overdriving them past their recommended amplier power-handling rangs, or past the point of amplier

clipping. Such damage is beyond the scope of the warranty.

CHOOSE THE AMPLIFIER POWER

We give you two power-handling numbers: connuous and peak. So these data suggest you can use any amplier with

a power capability equal or less the power-handling, but this rule is valid only if the amplier never clip any me.

Prevenng 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 amplier with a built-in limiter to prevent

clipping, in this case the rated power capability must be the same connuous power rang of the loudspeaker into the

same specied impedance (typically 4 or 8 ohms):

• To obtain the best result using FLASH12P / 8 ohm we suggest the use of PROEL HPX-900 amplier for a standard

stereo conguraon.

IMPORTANT: Clipping occurs when the signal at the output of any device in the system (not just the amplier) reaches its

maximum level. Proper operaon of a sound system includes being aware of the types of audio signals being reproduced,

controlling the output levels accordingly, and operang all the devices in the system so that no clipping occurs within

the signal chain.
