Company
C.E. Studio-2 is a Spanish electronics manufacturing company located in Valencia, one of the most active industrial centres of Spain. It was founded in 1982. Studio-2 began as a manufacturer of professional audio electronics. Today, they specialise in the design and the production of Power Amplifiers under RAM Audio brand. From the beginning all their products were characterised by their innovation and reliability. Both qualities are still “sine qua non” basic requirements for their own brand name RAM Audio products. At the beginning of the nineties and due to the proliferation of new sound products companies, a great demand for Power Amplifiers opened a new market for Studio-2 as an OEM manufacturer. In 1997, Studio-2 took the important decision to manufacture a new Series of Amplifiers under its own RAM Audio brand name, for the export market exclusively.
A new facility was built to house the exclusive manufacturing plant. At Prolight+Sound-Frankfurt 1998, the legendary up to 2000 W, BU Series was presented, which later became the higher-powered BUXII Series, up to 8000 W. In 2002, RAM Audio launched DQL Series with QuantaPulseswitching power supply, which later became DQX Series which included Ethernet network control. These series were RAM Audio’s response to their customers’ demand for light-weight amplifiers with power specs up to 7000 W. In 2006, RAM Audio designed a new age lightweight amplifiers, S Series, high power in really compact devices of 2 and 4 channels models up to 6000 W.
They can include several optional modules as Ethernet network control, DSP, etc After several designs of multi-channel installation and medium power cost-effective series, as T and RX ones, in 2011, RAM Audio launched to the market V Series, a new reference amplifier. 2 and 4 channels PFC machines for heavy-duty applications up to 12000 W of sustained power in all channels. These amps are equipped with optional high performance DSP, Ethernet control or AES3 inputs.
RAM Audio Power Amps are exported to over 40 countries worldwide and both, RAM Audio and its distributors, exhibit them in many national and international trade shows.

MDi Series
Pi is a multipurpose series of power amps for touring and installation applications, based on the legendary QuantaPulse™ switching mode power supply with an innovative class H 3 steps topology.
This series includes a completely renewed PMS™ which incorporates a set of protection systems in power supply and audio modules which works in real time continuously maintaining all variables of the amp within safe working threshold always. So, Pi amps are appropriate machines for the most exigent applications with the best reliability.
Pi amps have been designed with a non-symmetrical class H topology which allows working with very high voltages given incredible headroom and a great punch.
All these characteristics make Pi amplifier an interesting device to work with asymmetric loads to squeeze every last drop of power in each way of the sound system.
Pi series has an extra-large 4.3″ IPS display with capacitive touch panel whereby it is possible to control and manage every parameter of the amp and select all System Presets, Uses, User EQ and Snapshots created.
Also a powerful FIR DSP has been implemented in these amps with a software specifically developed for this series.
FEATURES
• Extra-large 4.3″ IPS display, capacitive touch panel user interface
