THE TSLC 20
The speaker-to-line converter that is true to the sound
Embedded Files
The True Speaker-to-Line Converter (TSLC) 20 is a high-quality, single-channel speaker-to-line level converter designed to help you record and analyze the sound of your audio amplifiers from their speaker outputs on your computer using your sound card. It is a true speaker-to-line level converter because, unlike other converters that lower the signal in the conversion process, introduce distortion due to the components used, or degrade the sound quality, it only converts the speaker level to line level without any signal loss and with maximum transparency. It also features a built-in –20 dB signal attenuator for situations where lowering the speaker level is needed.
Recording your audio or hi-fi amplifier is very useful in several cases:
For amplifier sound demonstrations or comparisons, for example on YouTube: this allows listeners to hear, in their own rooms and through their own speakers or headphones, a more precise and objective representation of how the amplifier actually sounds. This is a far more accurate and honest way to showcase an amplifier than recording the sound of the speakers connected to it in an unfamiliar room, which unfortunately is often not acoustically treated or properly set up for accurate recordings, whether due to inadequate equipment or limited technical knowledge. It is also more meaningful than reviews or oral descriptions of the sound, where the words used can be vague, subjective, influenced, or biased. Hearing the amplifier itself is very important for some listeners to make informed decisions when considering its purchase.
For personal comparisons: if you own several amplifiers, recording them and listening back can help you compare their sonic characteristics more objectively.
By analyzing your amplifier’s sound on your computer with audio analyzers, you can ensure that it is working properly. For example, you can check whether the channel balance is correct, whether it colors the sound or remains neutral, and then decide whether any adjustment or servicing is necessary.
The TSLC 20 is available in two versions: one with jack connectors and one with RCA connectors. Each TSLC 20 converts one channel, so you’ll need two units for a stereo setup. Finally, the TSLC 20 can be used in any situation where a speaker-to-line converter is required, for example, in car audio systems.
Handmade with an authentic passion for sound in France.
