The Ottocanali 12K4: extremely flexible and reliable. It offers a wide range of system control and monitoring functions as well as sound shaping options, a total of up to 12,000 W output power over 8 channels for lo-Z or distributed line systems all neatly packed into a double rack unit. As ‘stand-alone’ unit the Ottocanali 12K4 fits any venue. Excellent sound quality and ample output power stem from Powersoft’s unique approach to Class D amplification, making the Ottocanali 12K4 the ideal main system in any venue where performance is priority.
Powersoft’s legendary efficiency saves valuable energy, keeping both operational cost and ‘carbon footprint’ at a minimum: the Ottocanali 12K4 shines with outstandingly low power consumption and heat dissipation; this dramatically reduces costs from the AC mains supply and air conditioning/cooling systems - not to mention the benefits to the environment for a greener planet.
- Legendary Powersoft efficiency:
- Green Audio Power®: minimal ‘carbon footprint’ and operational cost of electricity (Energy Star qualification pending); additional ‘Energy Save’ function
- Compact and space saving: 2 RU, and standard depth 360 mm / 14.2”
- Driving low impedance and distributed line systems:
- Mixed lo-Z/hi-Z systems possible
- Bridged mode low impedance
- Up to 28 different output configurations possible
- Unique Powersoft technology for efficient, reliable, great sounding performance:
- Two universal switch mode power supplies with PFC (Power Factor Correction) each independently powering a set of 4 channels
- Fixed frequency switch mode amplifier output stages
- Patented amplifier output filters with ripple cancellation network
- Maximize performances, minimize consumption:
- Patented SRM (Smart Rails Management) technology allows to maximize the efficiency of the system and drastically reduce power consumption at any load and usage condition.
- Outstanding performance and operational safety:
- Excellent sonic quality by design, including amp clip limiters and patented ripple cancellation network
- Practical & versatile:
- Directly driving either low impedance loads or 70 V/100 V lines
- Capable of driving 2 loads
- A dipswitch set for each channel allowing selection lo-Z or hi-Z (70 V or 100 V) modes, with or without HPF filters set to either 35 Hz or 70 Hz
- A full set of auxiliary inputs for all channels granting redundancy for security purposes
- Front panel safety cover hiding output attenuators and ‘Energy Save’ switch
- Channel specific independent set of alarms triggered by potentially dangerous faults or generally unsafe operation conditions
- All signal/control connectors Phoenix industry standard
- Front-to-rear airflow cooling with variable-speed fan, temperature controlled
- Full protection circuitry:
- over/under AC voltage, DC
- troublesome signals (clipping, VHF, long-term RMS)
- thermal
- short circuit
- mute at power on/off
- Full four years warranty
Inštalačné zosilňovače, ktoré v našich podmienkach veľa z Vás používa nie len na inštalácie, ale pre ich výhodnú cenu ( až 8 kanálov audia v jednom chasy) ich vidieť aj vo zvukárskych rackoch.
Takže je tu úplne nová seria OTTOCANALI Powersoft. Vyrobca ponúka 2 modely aj s DSP a Ethernet pripojením, ostatné až do najvyšších výkonov nájdu uplatnenie všade tam, kde je potrebné mať k dispozícii veľký počet zosilovacích kanálov.
Seria OTTOCANALI je teda až 8kanalvý zosilňovač audia a vie pracovať tak do nizkoimpedančnej záťaze ako aj do 70/100V rozvodu súčasne. Séria ponuka výkonové rozpätie od 150W/4Ohm až do 1500W/4Ohm pre kazdý z OSMYCH zosilňovacích kanálov.
Príklad cenovej úspory pri použití 1ks OTTOCANALI 12K4 a 2kusov 4 kanálových LAB.GRUPPEN C48:4
Každý z kanálov ponúka 1500W/4Ohm
1 kus / 8 kanálov OTTOCANALI 12K4 Powersoft v cene 4995 eur bez DPH
2 kusy/ 8 kanálov LAB.GRUPPEN C48:4 v cene 2 x 3476 eur = 6952 eur bez DPH
