4.1. Features
Effective progressive ventilation system, with flow adaptable to the internal
temperature of the amplifier. It takes the air from the rear and is expelled from the
front.
Rotating controls for input attenuation in the frontal panel, easily accessible.
Power ON, Signal Presence (SIGNAL), Clipping (CLIP), and Protection Activation
(PROTECT) indicators.
Effective system of protections against short circuit, overheating and presence of
continuous signal, to avoid damage to the amplifier itself and/or the loudspeakers
connected to it.
Built-in anticlip circuit (signal clipping or saturation), always active.
Working mode selector: STEREO, PARALLEL and BRIDGE.
Input sensitivity selector.
Cut filter selector (CROSSOVER)
Symmetrical inputs through XLR3 connectors, plus 6.35 mm TRS jack inputs and
unbalanced inputs with RCA connectors. The XLR3 inputs provide a copy to the
jack and RCA connectors, which can act as LINK to another eLPA unit.
Amplified outputs with terminal block connectors and Speakon connectors.
Operation at 8, and 4, or 8 in bridge mode.
Warranty: 3 years.
5. INSTALLATION
5.1. Location, mounting, ventilation.
The eLPA amplifiers come in 19" rack format with two height units.
It is very important that, as a heat generator element, the amplifier is not completely
enclosed or exposed to extreme temperatures. The forced ventilation system that they
incorporate takes the air from the rear, directing it directly to the power modules and
diverting a part to the transformer and condensers, forcing it to exit through the cooling
tunnel by the front of the amplifier. Therefore, the passage of fresh air through the
forced ventilation tunnel should be favored, avoiding in the case of rack mounting an
excessive accumulation of heat inside the rack that would increase the probability of
premature failure of any of its electronic components. Likewise, it is advisable not to
place the power amplifiers under other devices, but on top of them, in order to favour
the thermal dissipation of the whole.
