19. Mute
Press this button to silence the audio temporarily, such as when you’re lowering the tonearm onto a record.
Because the Perseus uses a relay to perform the Mute function, it may take a second or so for this control to
respond. When the Perseus is in mute mode, an X will appear next to the speaker icon in the lower right
corner of the touchscreen. Press the button again to restore the sound.
20 – 23. Rear-panel controls
20. MM loading adjustment switches
These two arrays of four microswitches each adjust loading for the MM input. You can flick the switches
gently with a small screwdriver, a toothpick, etc. You can use the settings recommended by the manufacturer
of your cartridge, or experiment and use the settings that sound best to you. But always use the same
settings on both switch arrays. Below are the functions for each switch:
CAPACITIVE LOADING
SW1 and SW2 off: No capacitive loading
SW1 or SW2 on: 100 pF
SW1 and SW2 on: 200 pF
RESISTIVE LOADING
SW3 and SW4 off: 47 KΩ
SW3 on, SW4 off: 33 KΩ
SW3 off, SW4 on: 10 KΩ
SW3 and SW4 on: not recommended
21. MC loading adjustment knob
Turning this knob adjusts the loading for the MC inputs in a range of 0Ω to 999Ω. To see the setting of the
knob, push the Setup button the front panel and select MC Load on the touchscreen. Don’t worry about
getting the left and right channels to match perfectly; differences of 1 or 2 ohms are insignificant. If the load
is set all the way down (000) you will get no sound.
