#List of PCs, Peripherals, Home Appliances, etc._Magoichi ↑ Please use this as a reference for bulk purchases. 【Overview】 This is the EQ-211M graphic equalizer from Onkyo's nostalgic audio system INTEC275. There are four presets (HEAVY, SOFT, CLEAR, VOCAL), but of course, you can also register custom patterns. Recommended settings are HEAVY for hard rock and CLEAR for classical music. Although you can't make detailed settings like a mixer, you can customize it in 7 steps from 64Hz to 16kHz, so I think you can achieve the sound quality you want. Operation has been confirmed with ONKYO's integrated amplifier A-922M + CD player C-722M (photos 2-4). The day before yesterday, I listed Onkyo's famous pre-main amplifier "A-922M", and yesterday I listed the ONKYO CD player "C-722M" (all operation confirmed). ＜※1 About Operation Confirmation＞ It is working perfectly. However, we cannot completely rule out the possibility of damage during transportation. Of course, we will pack it carefully with bubble wrap, etc. Included accessories are the main unit (with power supply), RCA pin (red and white) x 2, R1 cord (blue) x 1, and instruction manual (photos 8-11). Unfortunately, the remote control is not included. It will be shipped via Rakuraku Mercari. Please note that we may reuse shipping materials on hand. Also, the buyer will be given priority even if there are comments being exchanged. 【Specifications】 (See photo 11 for details) Type: Graphic Equalizer Control Frequency: 64Hz, 160Hz, 400Hz, 1kHz, 2.5kHz, 6.3kHz, 16kHz Variable Range: ±12dB Input Sensitivity (FLAT): 150mV Input Impedance: 50kΩ Output Voltage (FLAT): 150mV Output Impedance: 1kΩ Total Harmonic Distortion: 0.05% (20Hz～20kHz, 1.5V output, FLAT) Power Consumption: 8W External Dimensions: Width 275 x Height 79 x Depth 305mm Weight: 2.5kg
