Connectivity redefinedWhat to do

The king of connectivity
That has never existed before – 12 highlevel inputs, 6 Cinch inputs, 14 DSP channels, 12 output stages with up to 160 RMS at 2 Ohms combined in an ultra-compact housing that has the footprint of just two envelopes. The new V TWELVE DSP is unmistakeably a technological milestone and the problem solver par excellence when it comes to upgrading multichannel premium sound systems in today's vehicles.

Connectivity redefined
What to do if a vehicle is already equipped with a premium sound system ex works, whose amplifier often already has more than 10 channels?  In many cases, a replacement is no longer possible, so that only an amplifier with the same number of highlevel inputs can be considered for upgrading the system. The V TWELVE DSP is the first amplifier worldwide that offers 12 highlevel inputs and just as many amplifier channels, a digital input and a HEC slot. The integrated DSP can handle this easily, since it comes with the incredible number of fourteen (14!) separate channels.

Virtual Channel Processing – this is how signal routing works today
The adaptation to modern OE sound systems via an increasing number of inputs has a significant impact on the complexity of the signal routing inside the amplifier. Especially when several input signals are mixed together and then split again into multi-way systems, conventional routing concepts quickly reach their limits. Audiotec Fischer's new multi-stage "Virtual Channel Processing", in conjunction with the recognized user-friendly DSP PC-Tool software makes it easy to realize even highly complex system configurations. Besides, it allows to freely assign our proprietary FX sound features such as "RealCenter" or "Augmented Bass Processing". But thanks to its enormous number of channels, the V TWELVE DSP is also a prime example for applications in which a 1 to 1 routing (IOR) makes sense.

The plus in speed – thanks to ACO
Such a huge number of channels requires ultra-fast hardware – Audiotec Fischer's proprietary 32 Bit ACO platform takes over all control tasks and ensures exceptional speed especially for data communication with our DSP PC-Tool software, but also for lightning-fast switching between up to ten possible sound setups. The fantastic sound effects associated with the ACO platform such as Augmented Bass Processing, StageXpander or RealCenter are just as natural with the V TWELVE DSP as a 12-channel input EQ including our Input Signal Analyzer (ISA) for easy analysis and compensation of the input signals from OE radios.

Sound quality without any compromises
Separate AD and DA converters of the latest generation from Asahi Kasei with a native resolution of 32 Bit ensure optimal sound performance, best possible signal-to-noise ratio and minimal distortion. Concerns that the abundance of audio channels and the extremely dense design could have an impact on the sound quality are completely out of place for a HELIX product.

  • Up to 160 W RMS output power per channel into 2 Ω
  • “Pure Class GD” concept for outstanding sound quality combined with best possible efficiency
  • Extremely powerful 64 Bit “fixed point” Audio DSP
  • ACO – Advanced 32 Bit CoProcessor platform for system and DSP features like:
    • ISA (Input Signal Analyzer) and InputEQ for easy analysis and compensation of input signals
    • SFX sound effects – Augmented Bass Processing, StageXpander, RealCenter & Co.
  • High power 12-channel highlevel input with up to 32 V RMS input sensitivity and ADEP.3 circuit
  • Two processed RCA / Cinch outputs
  • 1 to 1 Input / Output Routing (IOR) – same number of highlevel inputs and amplifier outputs
  • Virtual Channel Processing (VCP) allows even more flexible configuration for highly complex sound systems
  • HELIX Extension Card slot (HEC) for additional input / output modules like Bluetooth® Audio Streaming, High Resolution Audio Streaming via USB etc.
  • Compact design with low heat dissipation thanks to extraordinary efficiency

 

Special features:

Pure Class GD amplifier technology
Audiotec Fischers proprietary Pure Class GD concept takes the efficiency of conventional Class D amps to the next level. By varying the internal supply voltage depending on the amplifier’s input signals, idle losses are significantly reduced and overall efficiency is close to maximum at any time.
So heat dissipation is almost negligible thus allowing smallest heat sinks and most compact form factors. Besides that Pure Class GD amp outperforms conventional Class D designs in terms of sound quality by implementing a fully differential signal path and improved output filter design.

ACO – Advanced 32 Bit CoProcessor
The HELIX V TWELVE DSP incorporates an extraordinary powerful 32 Bit CoProcessor of the latest generation for all monitoring and communication tasks, both internally and externally. In opposite to the 8 Bit predecessor generation this MCU achieves way higher speeds with respect to setup switching and data communication with our DSP PC-Tool software. A further significant advantage is the integrated, native boot loader of the CoProcessor.
It allows software upgrades of all components of the integrated DSP in order to adjust the microcontroller-controlled ADEP.3 circuit for example to future requirements of the diagnostic system of factory radios or if the device will be extended with additional interfaces. In addition, thanks to the new flash memory, the ACO offers 10 memory locations for sound setups instead of the common two.

Smart highlevel input ADEP.3
Modern, factory-installed car radios incorporate sophisticated possibilities of diagnosing the connected speakers. In particular the latest generation of car radios are equipped with additional monitoring functions so that failure messages and loss of specific features (e.g. fader function) quite often appear if an amplifier will be hooked up – but not with the V TWELVE DSP.
The new ADEP.3 circuit (Advanced Diagnostics Error Protection, 3rd Generation) avoids all these problems without loading the speaker outputs of the OE radio during high volumes unnecessarily.

Start-Stop capability
The switched power supply of the HELIX V TWELVE DSP assures a constant internal supply voltage even if the battery’s voltage drops to 6 Volts during engine crank.

Power Save Mode
The Power Save Mode is incorporated in the basic setup. It allows to significantly reduce the power consumption of the amplifiers that are connected to the HELIX V TWELVE DSP once there’s no input signal present for more than 60 seconds. Please note that in many up-to-date cars with “CAN” or any other internal bus structures it may happen that the radio remains “invisibly” turned on for up to 45 min. even after locking and leaving the car! Once the “Power Save Mode“ is active the remote output and therefore the connected amplifiers will be turned off.
The V TWELVE DSP will reactivate the remote output within a second if a music signal is applied. It is possible to either modify the turn-off time of 60 sec. or completely deactivate the “Power Save Mode” via the DSP PC-Tool software.

Lovely Slate Gray Jewelry Box
I just received this Slate Gray jewelry box. It's really quite lovely and just the right size for my granddaughter's vanity. I'm really excited about giving it to her, for her 12th Birthday, to hold her better jewelry. It's so nice I'm going to order another one for my other Granddaughter's Birthday.

Songmics Slate Gray Travel Jewelry Box
I purchased the slate gray Songmics jewelry box for travel purposes. We take long vacations and have an upcoming 20 day cruise. I wanted a jewelry box that was compact enough to put in my carry-on bag, but still had room to hold a months worth of jewelry, especially to keep my necklaces for tangling. When this arrived, I was pleasantly surprised and the packaging was great, shipped in a sturdy box. so no damage to the jewelry box. The color is a rich gray and the 2 tier box, while small, holds a lot of jewelry. I wanted to purchase the ink black but could not justify paying twice the price of the gray one just to get it in black. It is small enough that it will fit in most any hotel/ship safe so I won't be sitting out in the room anyway. It has a strong magnetic snap that keeps the box from opening while in transit. The one negative for me is that the pierced earring card is so thick that my earrings barely go through to have enough room on the back side the slip the backs on. I may separate the double thick card, realizing it will not look as nice but will be more functional. The bottom half of the box will hold bracelets up to 1 1/4" wide. There is enough room under the earrings card to place pendants, additional earrings, etc. The necklace holder is designed to hold 5 necklaces, but I added one more by going across the top, end to end, to prevent tangling. I also placed smaller hoop earrings in the ring holder which holds them securely. This box held 7 bracelets, 2 of which were wide, 5 rings, 9 necklaces (I placed 3 in the bottom of the box, and had room for 23 pair of earrings (some placed in the ring holder and in the bottom of the bo)! I would buy this again in a heartbeat.
