Power Input Port
By adopting a Furutech terminal milled from pure copper optimized for audio, it transmits the input electricity without disturbing the purity.
This is a port that receives RCA input from an external turntable device, and the input sensitivity is 5 mV in MM mode and 0.5 mV in MC mode.
6
Turntable Input
The phono (MM/MC) signal device is a device that receives a low audio signal and sends it out with a high output, so it is greatly
affected by the signals of nearby external devices. Therefore, it is recommended that router devices such as Wi-Fi routers be kept at
least 3 m away from this product.
7
Unbalanced Input This is a port that receives RCA input from an external source device, and the input sensitivity is 1 Vrms.
Changes the gain level of the equalizer amplifier. (Amplifier circuit required to reproduce analog records)
· MM: Select an MM (moving magnet) cartridge with high output voltage.
8
Turntable Cartridge · MC: Select an MC (moving coil) cartridge with low output voltage. Selection Switch If you select MC while using an MM cartridge, you must be careful because the impedance increases the volume and produces
an unbalanced sound without a high frequency.
The MC cartridge input signal is designed based on 0.5 mV. If you are using a turntable with a smaller output than this value, you may need to connect a separate step-up transformer. (A step-up transformer is not supplied with this product.)
This provides a rich low-pitched listening environment by connecting with an active subwoofer unit.

3. HPF Control Function of the H/F Crossover
· When using the bi-amping function, the frequency range sent to the treble
area is changed so that the treble can be reproduced more faithfully. ·
Speakers with a two-way or more structure have built-in networks inside.
If you set the frequency range below the built-in network crossover value, the
network does not send low-range frequencies, so the speaker reproduces treble
notes more faithfully. · The treble frequency range can be varied from 0.58 to
6 based on -3 increments.
