Evolution 1A1 – 1 OHM

1 x 400 Watt @4 ohm | 1 x 650 Watt @2 ohm | 1 x 1,000 Watt @1 ohm | REGULATED

Description

Crescendo Evolution 1A1 – 1 OHM adalah amplifier 1 kanal / monoblok yang mampu bekerja stabil hingga beban serendah 1 ohm dan menghasilkan tenaga 1.200 Watt. Kualitas bass yang dihasilkan terasa  bertenaga dan terkontrol dengan baik. Terlebih lagi kemasannya kecil sehingga mudah dipasang dimana saja, termasuk di bawah jok mobil.

Crescendo Evolution 1A1 – 1 OHM bukanlah penerus dari Evolution 1A1, melainkan sebuah desain amplifier dan preamplifier yang sama sekali baru.

Beberapa fitur modern yang dimiliki Evolution 1A1 – 1 OHM adalah:

Suplai power teregulasi sehingga tenaga (Watt) yang dihasilkan oleh amplifier stabil pada kondisi voltage mobil berapapun. Misalnya:
Voltage mobil 14,4 Volt & subwoofer 1 ohm = tenaga 1.000 Watt
Voltage mobil 12,0 Volt & subwoofer 1 ohm = tenaga 1.000 Watt
Jadi amplifier ini tidak membutuhkan penyetabil voltage yang mahal harganya.

Amplifier memiliki fungsi auto on sehingga dapat menyala otomatis tanpa kabel remote dari Head Unit. Fungsi ini sangat cocok untuk dipasangkan dengan Head Unit OEM mobil yang tidak memiliki kabel remote.

Preamplifier memiliki opsi Level Masukan Tinggi (High Level Input) atau Level Masukan Rendah (Low Level Input) sehingga dapat dipasangkan dengan Head Unit OEM mobil ataupun Head Unit after market.


Crescendo Evolution 1A1 – 1 OHM is single channel / monoblock amplifier that is stable down to 1 ohm subwoofer load and pumps out 1,000 Watt. The bass reproduction is powerful and well controlled. On top of that, the size is sleek enough to fit under the front seat.

Evolution 1A1 – 1 OHM is not the new version of Evolution 1A1, it is a whole new amplifier and preamplifier design.

Some modern features of Evolution 1A1 – 1 OHM as follows:

Regulated power supply as to produce consistent power (Watt) regardless of car’s voltage. For example:
14.4 Volt car voltage & 1 ohm subwoofer load = 1,000 Watt of power
12.0 Volt car voltage & 1 ohm subwoofer load = 1,000 Watt of power
So, this amplifier does not need any expensive voltage stabilizer.

Auto on function can detect music and automatically turn on the amplifier even though the remote cable is not applied. This function is very useful to connect the amplifier to OEM Head Unit without remote output.

Preamplifier has 2 options of High Level Input or Low Level Input so it can be used with both OEM Head Unit or aftermarket Head Unit.
