BATTRIAA S.E.


BATTERY POWERED NON FEEDBACK RIAA AMPLIFIER


BATTRIAA is a State of The Art external RIAA-amplifier with both MM as well as MC sensivity.


BATTRIAA has a built in battery power supply with automatic charging circuitry.


BATTRIAA has been taken from the most expensive HOLFI preamplifier Pre NB1 - both in circuitry design as well as choice of components.


BATTRIAA has variable gain in the MC stage. Thus it can be used with any cartridge with optimum result.





BATTERY POWERED NON FEEDBACK RIAA AMPLIFIER



BATTery driven RIAA.
As indicated by the name BATTRIAA is a RIAA amplifier with battery power supply. BATTRIAA contains two 12 Volt/2.9 Ampere hours sealed and maintenance free batteries. The use of battery operation secure the lowest possible level of noise. In practise 20 dß lower than solutions based on active regulation. Just noise is a parameter, which is extremely important for an amplifier that has to maintain the low and extremely vulnerable signal from a cartridge. That the battery power supply is not surpassed by any conventional power supply can be seen by the fact that the quite small batteries inside BATTRIAA can deliver more than 50 Ampere for several seconds. The automatic charger makes sure the batteries are always on top, which secures a battery life span of minimum 5 years. When the batteries turn old, they gradually loose their good abilities. Consequently HOLFI recommends a battery change every 5 - 8 years. A change of batteries will cost less than one/tenth of the price of the BATTRIAA.


The RIAA amplifier from Pre NB1.
The components in BATTRIAA are identical to those used in HOLFI's State of The Art preamplifier Pre NB1. These components have been chosen purely from sound quality point of view. The circuitry design, the battery operation and the WBT phono sockets are the same as used in Pre NB1. The MC stage amplifies the current signal from the cartridge instead of (as normally seen) the voltage signal. MC cartridges deliver a very low voltage signal, but as a current producer they deliver as much as MM cartridges. Considering the fact that bipolar transistors are current producing components, it seems obvious to utilize the current amplification along with MC cartridges. This will give the lowest possible distortion and noise. The amplification in the MC stage can be varied in 4 steps, which means that BATTRIAA practically can be used optimally with any cartridge. Like all HOLFI amplifiers BATTRIAA is totally without global feedback to secure a homogenous and easy flowing musical reproduction. The implemented RIAA correction is featuring chosen and measured coal resistors as well as copper foil capacitors to ensure the highest possible precision as well as the optimum sound quality.


State of The Art.
The sound quality from BATTRIAA must be experienced. Besides not being behind any other RIAA amplifiers as to openness, richness in details and dynamics, BATTRIAA sets new limits to authentic sound and quietness in the sound stage.
