Description
Connect your turntable to the XLR input and profit of the balanced signal path. Symmetrical, or also called balanced, transmissions consist
of a hot and a cold (also called + and -) signal. Both signal chains effectively carry the same musical information. A balanced gain stage can
now extract the final musical information out of the +/- signals and subtract, remove, all noise that could potentially be added along the transmission.
As there are two separate signal chains, we also needed two individual amplifier sections.MC cartridges or balanced MM cartridges* are a
necessity for fully balanced operation, and the new XLR inputs enable you to reach new levels of pristine phono amplification without any added interference and unprecedented low noise floor.
*Please note: typical MM cartridges are not compatible with balanced phono stages as they will exhibit increased noise in the right audio channel
due to the grounding of the internal cartridge generator. Modified, special „balanced“ versions of MM cartridges are available and only those MM
cartridges should be used with the balanced inputs of the E-Glo F B. Of course, any type of MM cartridge (balanced and unbalanced) can be used on the regular
single-ended RCA inputs. Please consult your dealer or E.A.T. representative for further information.
Hybrid Tube Topology
The first stage, the aforementioned balanced gain stage, consists of three discrete semiconductor operational amplifiers. After treating the balanced signals symmetrically, they are added back together and processed by the first of the two discrete RIAA equalisation stages. By keeping the gain stage fully symmetrical the signal to noise ratios are optimized, giving the EQ section the best source to work its magic on.
The second stage is a single-ended hybrid tube-transistor amplifier composed of the two ECC83S triodes and one transistor.
This stage includes the second RIAA EQ and a switchable subsonic-filter.The output stage is made up of a dual discrete semiconductor operational amplifier that converts the unbalanced signal to a balanced one and ensures a low output impedance of the preamplifier. Low DC offset at the outputs is maintained by dedicated DC servo circuits.
Discrete Circuitry
The E-Glo Petit B uses fully discrete audio circuitry throughout its complete design. A discrete circuit is composed of electronic components which are disparate, individual devices, also called discrete components. Countless hours of listening tests and years of experience have shown us that even the very best IC (integrated chip) Op-Amps do not tend to be so neutral, natural, dynamic or vivid. Standard phono pre-amplifiers with integrated circuits have a few tens or hundreds of components, but discrete designs will employ hundreds or thousands of components by comparison.
Cartridge Loading Options
Two turntables can be connected at the same time & easily set-up on the top panel. Each input settings are stored in the memory.
Large ranges from 40dB up to 70dB are possible. A fully balanced design makes all the difference here, handling amplification levels this high. The E-Glo Petit B can be perfectly matched with a wide variety of cartridges and perfectly integrated into any Hi-fi system, matching the volume levels accurately to other sources like CD players or streaming devices. The RCA and XLR outputs can be used at the same time for extra flexibility when connecting multiple audio systems.
Two load impedance ranges – high and low – are available. When switched to „low“, standard MC options can be accessed and, in a bit of an unusual manner, the E-Glo Petit B even provides a „high“ setting. That way, even the load impedance for MM cartridges can be fine tuned, not forcing you to stick with the typical 47k Ohms setting that is usually found elsewhere.
A Feast For The Eyes
The handsomely styled E-Glo Petit B is housed in a full aluminium chassis, its valves peering through with new selectable valve illumination. Across the front section are rows of switches for instant access to all settings – no need to „get inside“ to set the E-Glo Petit B for your cartridge of choice.
