Phono EQ.2

Many pre- and integrated-amplifiers available on the market today do not include dedicated phono inputs. Or if they offer one, most often it is nothing more than an afterthought as far as quality and functionality. The inputs fulfill only the requirements of the marketing department to add a feature to the checklist.

Vinyl has always played an important role at Octave. Ever since the company was founded, nearly every Octave pre- and integrated-amplifier model produced has offered analog aficionados the option to add a perfectly tuned, built-in phono input - with perfect adjustment possibilities (RIAA curve) according the pickup used.

Surely there are many music lovers who own a turntable but have yet to own an Octave component, and Octave did not want to leave them empty handed. The brand new Octave EQ.2 separate phono-preamplifier fills this gap. The EQ.2 is a compact yet complete MM/MC phono stage housed in a magnetically shielded chassis with an external power supply.

This offers many benefits - as for example the persistent 50 or 60 Hz frequency of the power line cannot influence the very low and quite sensitive input voltage coming from the needle.

It doesn't matter whether one prefers Moving Magnet or Moving Coil pickup systems; their sensitive voltages meet real-world impedance and gain values at the input stage. The impedance is selectable between 62 and 1,000 Ohms (at either 62, 75, 97,100, 125, 146, 170, 200, 250, 340, 500 and 1,000 Ohms), while a choice of four steps for the gain (58, 62, 68 and 72 dB) in the EQ.2 allows one to perfectly match the sensitivity to the phono cartridge. The feature list is completed with the addition of a highly fine tuned Subsonic filter to offer protection for your bass drivers.

Following Octave's uncompromising approach to quality, all connectors are gold plated and the meticulously selected high-grade internal components are sourced from the most highly respected manufacturers. But ultimately it is all about performance and the sound of the EQ.2 performs most impressively in this regard: the EQ.2 is a true Octave and brings uncompromised Octave analog quality to everyone.

Tube based external phono preamplifiers are the preference of music lovers who prefer the sonic virtues of analogue reproduction. Modern MC (moving coil) pickup systems, with their low output signal, cannot be connected to a tube based phono stage without an additional step up transformer to keep the total noise to an acceptable level.

When OCTAVE was founded, Andreas Hofmann began developing phonostage preamplifiers with an electronic MC input, because transformers are very sensitive to magnetic stray fields and they are limited in respect of the load impedance and the amplification factor. The OCTAVE Phono Module is a full feature phone preamplifier which allows the use of three different Input modules and three different Output modules.

The three Input modules can be used simultaneously. There is an single-ended (RCA) MM (moving magnet) module, with switchable Input Impedance 1k Ohm and 47k Ohm. There is an single-ended (RCA) MC module featuring switchable Input Impedance between 50 to 1k Ohm, with Gain adjustable in two steps.

There is a balanced MC Module with XLR input jacks, featuring the same Impedance and Gain adjustment as in the unbalanced MC module. The Phono RIAA equalization stage is realized with a tube circuit based on the phono section of the highly-regarded OCTAVE HP 500 SE preamplifier. The RIAA Stage utilizes three tubes to ensure the high gain required by the RIAA correction.The specific configuration, with solid-state devices in the MC input and tubes in the RIAA output stage, allows the realization of a phono preamplifier which surpasses any and all tube designs in respect to spectral clarity and the signal to noise ratio.

The optional Output modules complete the OCTAVE Phono Module: There is the standard single-ended Output Module featuring dual RCA outputs, one with fixed level, the other with passive regulation. The next is the single-ended “ Direct Drive “ Module, also with dual RCA outputs, where the regulated output is buffered to reach a low output resistance to allow for driving a power amplifier directly.

There is also the Balanced (XLR) “Direct Drive” Module, featuring complex circuitry containing a tube and some integrated circuits that form a perfect balanced converter. This regulated output is also able to drive any power amplifier directly, while also allowing the level of the balanced output to be reduced to operate with the balanced line level inputs of a preamplifier. The OCTAVE Phono Module utilizes an external power supply.
