audison Prima AP 4.9 bit 4-Kanal Endstufe mit DSP
Compact amplifiers with built-in DSP featuring 7 "Drive" presets,
providing the ability to take complete advantage of the bit Drive potential with
just a simple selector: the Audison team has developed 7 DSP presets, fine-tuned
for the most common setups specific to the amplifier model. The Audison Prima
amplifiers are all D Class Full Range. Quick release connectors facilitate
Plug&Play installations using wiring kits specific for different car models,
maximum integration with the vehicle’s OEM system.
The Audison Prima amplifiers are characterized by extremely compact
dimensions and elegant look. For the first time, Audison has made an amplifier
equipped with a built-in processor. This feature opens a new era: the incredible
power of our DSP is now put at the service of OEM Integration. The presence of
the processor ensures full compatibility of Prima amplifiers with the bit Drive
technology: the amplifiers feature seven Drive presets corresponding to
different system setups, selectable according to your own preference via a
rotary dial. This solution reduces the setup time to a minimum, also eliminating
any possibility of error. It is also possible to create your own preset through
the PC software supplied with the product, giving you finger-tip control of all
the DSP’s parameters. Additionally, thanks to the bit Drive Portal, more presets
can be downloaded and shared with the other users in the community. The built-in
DSP functions are similar to those found on bit Ten and bit One, but there is
something new and important on the equalizer output. Unlike a 31-band graphic
equalizer, the AP bit equalizer features 10 parametric “poles” to draw the
target curve via the PC software. This solution preserves a noticeable amount of
resources for the DSP, with the plus of providing better acoustic response,
thanks to the drastic reduction of phase variations found in graphic equalizers.
The R&D team succeeded in the difficult task of condensing traditional
Audison power and quality into the palm of your hand. The reduction in dimension
was achieved with the use of a special power supply, never employed in Car
Audio, along with the most advanced electronic components available in the
market. All of this together, provides the ability to achieve high power
delivery, ensuring, at the same time, unheard of thermal stability.
To
respond to the need of connecting the amplifier to the OEM amplifiers power
supply cables, often with reduced gauge, the Audison R&D team equipped the
Prima amplifiers with an innovative management circuit which constantly monitors
in real-time the power supply current consumption. If a high amount of current
is requested for a long duration, which may heat up the cables, the circuit
immediately limits only the power peaks, letting the amplifier continue to play.
This solution provides higher safety and reliability in OEM upgrade
applications. The innovative power supply stage ensures very high efficiency and
stability for the amplifiers, capable of short term operation with as little as
7 Volts! This eliminates the numerous problems and disadvantages integrating
aftermarket systems with vehicles featuring Start&Stop technology. In order
to solve the problem associated with OEM amplifiers that feature signal
interruption, shutting down when a proper speaker “load” is not present as often
found in aftermarket Integration, the Prima amplifiers feature ASP (Automatic
Speaker Presence). Available as an optional plug-in accessory, this circuit
provides the ability to simulate the OEM speakers’ presence during the short
time frame the head unit performs the check after being turned on, thus avoiding
any interruption of the signal being sent to the amplifier. The Prima amplifier
line is made up of three models featuring a nine channel DSP, all channels
independently adjustable via PC software.
AP4.9 bit
4 channel amplifier featuring 9 channel built-in processor.
AP4.9 bit amplifier was designed for the Integration into OEM front/rear
systems where a lot of power is required. The built-in processor, that this
amplifier shares with the AP8.9 bit, provides the ability to assign the pre-outs
to the AP1 D amplifier to drive a subwoofer, to the AP4 D amplifier to have 4
additional amplified channels exceeding 1080 W @ 4 - 2 O total power.
