For use in verifying and evaluating the operation of phono equalizers and phono input circuits.
High-precision design born from in-house inspection jigs.
High-precision inverse RIAA characteristics refined through repeated measurements.
Passive design, no power supply required.
Compatible with a wide range of audio equipment
You can use the available PHONO input terminal as a LINE input terminal!
Perfect for testing and checking phono equalizers and amplifiers with phono inputs!
PHONO input-enabled passive inverse RIAA equalizer (RIAA converter) for measurement and evaluation.
Even without a record player, you can recreate the PHONO output of a record player simply by connecting it to a device with analog output, such as a CD player, other players, DAC, or audio interface.
This is a passive inverse RIAA equalizer that corrects the signal using the opposite RIAA characteristics compared to record playback, converting line-level signals from CD players and DACs into signals equivalent to MM phono input signals.
This device is ideal for checking the sound quality, characteristics, and operation of phono equalizers and amplifiers equipped with phono inputs. It can also be used to connect line output devices to amplifiers that only have a phono input available.
Because it uses a passive circuit, no power supply is required. Simply connect it and you can use it easily.
This product is an inverse RIAA equalizer that was developed with the purpose of evaluating and verifying the operation of the PHONO input circuit of the "TUBE-P01J".
Through repeated prototyping and improvements as a jig for evaluation and verification, we pursued high precision in inverse RIAA characteristics and a flat frequency response.
Furthermore, we focused on user feedback that "even though they own equipment with a PHONO input, they don't own a record player and therefore can't utilize it."
In addition to measurement and evaluation applications, this product was developed with practical features in mind, such as the ability to connect line output devices like CD players and DACs to the PHONO input.
This product is not intended to reproduce the sound of records, but depending on the circuit configuration and design of the phono equalizer it is connected to, it has the potential to allow you to enjoy the unique tonal characteristics and textures of that equipment even with a line source.
Try this new way to enjoy your music: using your favorite phono equalizer with CD players, DACs, and other devices.
■Behind-the-Scenes Development Stories■
The development was initiated during the pre-shipment inspection of products equipped with PHONO input, including the FX-AUDIO- "TUBE-P01J".
Traditionally, inspections were conducted using actual record players, but this presented challenges such as requiring installation space and being cumbersome to manage as inspection equipment, including the management and replacement of cartridges and styluses.
Therefore, we began development of an in-house inspection jig that could verify PHONO input using only line output devices.
Through repeated prototyping and measurements, we thoroughly pursued accuracy in the inverse RIAA characteristics and a flat frequency response.
After achieving sufficient performance as a jig for in-house inspection,
"Even though I have an amplifier equipped with a PHONO input, I don't own a record player or LP records, so I'm not able to utilize the PHONO input."
We also noted that there are quite a few users who feel this way.
We have refined this product, which can be used not only for evaluation and measurement purposes but also as a conversion adapter to connect audio equipment with common line outputs, such as CD players, DACs, and audio interfaces, to PHONO (MM) inputs, and have commercialized it as "RE:EQ-00J".
[Product Features]
■ Effectively utilize unused PHONO inputs as LINE inputs
Even if you don't own a record player, you can connect line output devices such as CD players or DACs to effectively utilize the previously unused PHONO input.
*In particular, if you are not currently utilizing the PHONO input of the TUBE-P01J, you can add this product as an optional part to create a second LINE input.
■ For use in verifying and evaluating the operation of phono equalizers and phono input circuits.
It can be widely used for development and verification purposes, such as checking the sound quality, evaluating characteristics, and verifying the operation of phono equalizers and amplifiers equipped with phono inputs.
■ High-precision design born from in-house inspection jigs
Based on an in-house inspection jig developed to solve the challenges of inspection work using record players, we have refined it into a product that combines practicality and reliability.
■ High-precision inverse RIAA characteristics refined through repeated measurements
Through repeated prototyping, measurement, and refinement, we pursued high accuracy in the inverse RIAA characteristic and a flat frequency response. This high-precision design ensures reliable use even for evaluation purposes.
■ Passive design requiring no power supply
A passive circuit that requires no power supply. It's unaffected by power supply noise and can be easily used simply by connecting it.
■ Compatible with a wide range of audio equipment
It supports connection to a wide range of audio equipment, including CD players, DACs, and audio interfaces equipped with standard line outputs (RCA). It provides easy connection to PHONO (MM) inputs.
[Notes]
This product is an equalizer designed exclusively for connection to MM-compatible PHONO input terminals.
This device is designed for MM-compatible inputs only and will not function correctly with MC-compatible phono inputs.
Do not connect to line input terminals (AUX, CD, TAPE, etc.). (Playback will not be possible with normal sound quality.)
Because it is a passive circuit, the output signal is attenuated from line level.
