PRE-TC10review
I have used this excellent pre for a diy project where TC-10 drives Nr.2 DSP Tinisyne managing two full 2.1 systems. Perfect for a lot of DIY projects where an high quality preamplifier is needed. Thanks Audiophonics, always a reference.

PRE-TC10 review
I have posted a review of this recently bought product at ASR:
https://www.audiosciencereview.com/forum/index.php?threads/audiophonics-pre-tc10-preamp-with-tone-controls-review-and-measurements.44930/
The preamp function is good at affordable price, it is helpful especially in cases we use a record player or cassette recorder. However, there was a QC failure with this product, the negative voltage regulator LM337 did not work and sent -23V to the LME49720 negative supply pin. This, together with +14V positive supply (correct value) made total supply voltage of 37V and this exceeds datasheet absolute maximum value which is 36V. The op amps have survived and I have replaced the faulty LM337 for a new part. However, this should have been tested by the manufacturer.

PETIT EGALISEUR BIEN UTILE
J'ai intégré le TC10 entre un DAC et des enceintes actives et cela m'a permis de conserver mes enceintes qui n'avaient pas de réglage de tonalité
Donc objet précieux et rare pour ceux qui ont besoin comme moi d'augmenter les HF et de modérer les BF pour (bien) entendre...
Merci AUDIOPHONICS ...

Perfect for a Headphone System
I Had this product in the shelve for a long time because i had not found a good use for it, But when I bought an amplifier set for headphones I found the perfect match to integrate this preamp, the tone controls make all the difference.

Petit boitier qui fonctionne correctement
Qualité sonore acceptable. Voyants rouges trop lumineux. Je l'utilise pour seulement une écoute à bas niveau (ambiance,...) sur mon ampli qui n'a aucun correcteur de tonalité ni loudness, quand la source est trop linéaire. Il répond à mes attentes.
