Celectron Audio LT10P, User Manual

GENERAL INFORMATION

Thank you for having chosen a 

CELECTRON

 product.

The 

LT

 Series by 

CELECTRON

 is an extended range of active and passive speaker systems with plywood cabinet 

offering the renowned 

CELECTRON

 sound and a high-level performance in a reliable and affordable package. For the 

construction of the 

cabinets we have used plywood, a very lightweight and durable material that makes moving and 

installing these speakers 

very quick and easy. Strong, anti-scratch paint and steel grilles with an internal foam layer 

provide proper protection for years of service. The dual-angle pole holder featured in LT8, LT10 and LT12 models 

offers the possibility to obtain a 

more uniform coverage of the audience.

For the high frequency reproduction of 

LT

 Series we have designed wide-dispersion horns, able to provide constant 

coverage for large audiences and detailed response with low distortion. The high-excursion woofers, together with 

carefully tuned vented cabinets, offers an extended response with deep and tight basses.

4 passive models are available, featuring carefully designed crossover filters with HF electronic protection. The choice 

of black or white cabinet, built-in flying points and a wide range of accessories make them suitable for any kind of fixed 

installation.

The LT loudspeaker systems can be combined with the SW subwoofers capable of providing the perfect low frequency 

extension for each model of the series.

INSTRUCTIONS (FIG. 1 / 2 / 3)

1. 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 that splits the power signal

into a low frequency section, sent to the woofer, and a high frequency section, sent to the tweeter/driver. The frequency

transition is around 2KHz. The INPUT has this pin connection:

PIN1+ (or TIP): positive power signal (usually red wire)

PIN1- (or SLEEVE): negative power signal (usually black wire)

2. LINK (SPEAKON)

Output of the power signal to be sent to an another satellite loudspeaker. INPUT and LINK connectors are connected

in parallel.

CHOOSE THE AMPLIFIER POWER

We give you three power numbers: continuous, program and peak.

So these data suggest you can use any amplifier with a power capability in the range between continuous and program, 

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 in the range between continuous and program power 

rating of the loudspeaker into the same nominal impedance (tipically 4 or 8 ohms):

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.
