AC One Analog Controller
The AC One analog audio controller has been designed to
be used in high-performance applications that employ small-
to medium-size full-range systems with subwoofers. Its
excellent audio per
formance, dynamic range of 117 dB,
extremely low noise level, and outstanding price-perform-
ance ratio make the AC One an advantageous alternative to
conventional crossover and controller solutions. It is possible
to meet the tough demands of modern audio applications –
such as high sound pr
essure level, coverage, and sound
quality – only by using a biamped loudspeaker system which
can fully separate, amplify, and reproduce the audio signal´s
frequency ranges. The PowerMax 12 crossover function
brings the low-frequency performance of bigger systems to
compact systems. The AC One guarantees highly economi
-
cal system applications without loss of performance, and
helps to save on application space.
Inputs and outputs are active balanced. The inputs can be
fitted with optional high-quality input transformers (NRS
90208). The outputs featur
e output relays which protect
against unwanted noise in case of power failure.
The new PowerMax 12 crossover function (patents pending)
makes the best possible use of amplifier output power and
loudspeaker transmission capacities. Compared to other reg-
ular crossover designs on the market, PowerMax 12 delivers
an extra 3 dB SPL at the crossover point, something which
cannot be achieved by normal EQ´ing alone. In addition,
speaker overload and amplifier clipping are dramatically
reduced. The PowerMax 12 crossover function silences the
oft-hear
d complaint: “It needs mor
e punch and definition.”
In addition, a 12-dB (Q: 1.0) lo-cut filter and a unique
3-band equalizer featuring the patented LPN filter allows for
flexible, easy
, and quick system adjustments.
