CARATTERISTICHE
LR 604 - LR 604 XR: Amplificatori a quattro canali di dimensioni compatte e dalle
elevate caratteristiche musicali. I tratti fondamentali della sofisticata circuitazione
sono: stadi "FRONT END" realizzati con due stadi differenziali complementari, stadi
finali costituiti da transistors in connessione Darlington, transistors finali con capacitÃ
in corrente pari a 15 A ed alimentatore PWM a MOSFET dall'elevata riserva di
energia.
LR 604: Quattro canali, singolo o doppio ingresso, previsto per il funzionamento a 4,
3 e 2 canali.
LR 604 XR: Quattro canali, singolo o doppio ingresso, crossover elettronico a
regolazione lineare con possibilità di esclusione, uscita HI-PASS/BY-PASS, previsto
per il funzionamento a 4, 3 e 2 canali (crossover escluso) oppure 2 canali per l'HI-
PASS e SUB stereo/mono (crossover inserito).
PRECAUZIONI
· Per un buon funzionamento dell'apparecchio è importante accertarsi che la tempe-
ratura nel luogo dove esso è installato sia compresa tra 0 C e 55 C.° °
· Il luogo prescelto per l'installazione deve essere ben ventilato ed asciutto.
· La tensione di alimentazione è di 12 VCC con negativo a massa. Accertarsi che le
caratteristiche dell'impianto elettrico del veicolo siano adatte per questo apparecchio.
· Per una maggiore sicurezza di guida si consiglia l'ascolto ad un livello tale da non
coprire i suoni provenienti dall'esterno dell'auto.
INSTALLAZIONE
Il fissaggio si effettua mediante il serraggio nelle apposite sedi delle 4 viti e relativi
distanziali in dotazione. Per un'ottima riuscita dell'impianto si consiglia di usare i prodotti
della linea audison cable che comprendono: cavi di alimentazione, di segnale, per
altoparlanti, connettori RCA e tutti gli accessori per il completamento del cablaggio.
AVVERTENZE
· INGRESSI: Nell'eventualità che il radioriproduttore non avesse in comune la massa
di uscita con il telaio si dovrà collegare la calza del cavo schermato con il telaio del
radioriproduttore.
· USCITE: Non collegare in alcun caso tra loro oppure a massa le uscite -R e -L. Nel
caso si utilizzi un filtro crossover accertarsi che esso non abbia la massa in comune
tra i canali.
· REGOLAZIONI: Nel caso si udissero fenomeni di saturazione a livelli di volume
non elevato, significa che il segnale esce distorto dal radioriproduttore. Portare il
controllo di volume del radioriproduttore verso un livello più basso fino alla
scomparsa della distorsione. Regolare successivamente i livelli di taratura dell'ampli-
ficatore fino ad udire lievi fenomeni di saturazione.

FEATURES
LR 604 - LR 604 XR: Four-channel amplifiers with compact dimensions and
excellent musical performances.
The outstanding features of their sophisticated circuitry are: "FRONT END"
stages realized by two complementary differential stages, final stages made of
transistors in Darlington connection, final transistors with in current capacity of
15 A and MOSFET PWM power supply with high energy reserve.
LR 604: Four channels, single or double input. It can work with 4, 3, and 2
channels.
LR 604 XR: Four channels, single or double input, electronic crossover with
linear adjustment which can also be excluded, HI-PASS / BY-PASS output. It can
work with 4, 3, and 2 channels (crossover off) or with 2 channels for HI-PASS and
SUB stereo / mono (crossover on).
PRECAUTIONS
·In order for this device to function properly it's important that it is installed in a
spot where temperature doesn't fall below 0°C (32 F) or rise above 55 C (131 F).° ° °
· It must be installed in a dry and well ventilated spot.
· Power supply voltage is 12 VCC with negative to ground. Make sure that the
characteristics of the vehicle electrical system are compatible with this device.
· For safe driving we advise to listen to music at a volume level that won't drown
external traffic sounds.
INSTALLATION
For mounting use 4 self-threading screws and protective plastic rings provided.
For a very good result we suggest to use audison cable products to complete your
installation. These include: power cables, signal cables, speaker wires, RCA
connectors and all accessories needed to complete the wiring.
WARNINGS
· INPUTS: If the radio-cassette player doesn't share the output GND with the
chassis, the braided shield of the shielded cable must be connected to the radio-
cassette player chassis.
· OUTPUTS: Never connect -R and -L outputs to ground or to each other. If a
crossover filter is used, be sure its two channels don't have a common ground.
· REGULATIONS: If you hear saturation phenomena at moderate volume levels,
it means that a distorted signal is coming from the radio-cassette player. Turn
radio-cassette player volume down until there's no longer any distortion.
Then adjust the amplifier calibration levels until you hear slight saturation
phenomena.
