This EQ is imported from Japan, very rare item. You will never find this in US. Similar item in US is ERA-G320. Ideal of CDA-5755 is ERA-G320 with slave CD player.
Differences between ERA-G320 and CDA-5755. When ERA-G320 is made two body parts, Brain unit and Face plate, CDA-5755S is made in one body (1DIN sized). CDA-5755S is compact 1Din size, It will fit into 1DIN opening space, such as pocket underneath the head unit etc.
CDA-5755 does not have 3WAY OUT(Features that divide the full range audio signal to HIGH, MID, LOW). CDA-5755 has built in CD player.ALL other features are the same as ERA-G320. This unit is not a stand alone unit but require an Alpine head unit with Ai-NET control.
You can recognize whether your head unit has feature of Ai-NET by looking the model number. The third character must be "A" For example, CDA, TDA, MDA, etc. Some of the functions may not be able to control after connecting with Alpine Head Unit (with Ai-net) such as volume, L/R balance, SW level etc.. It will be controlling by Alpine Head Unit (depending on model as well) instead. All language is in English.
I disassembled the entire unit and checked to see if every single parts are working properly and repaired when necessary. I rebuilt the CD Mechanism, cleaned the optical Lens, look for cracked soldering iron and made repair as necessary. Everything is working perfectly now.
6 Pattern DSP Surround (Normal/Stadium/Live/Church/Dance/Hall). EQ Frequency (63Hz/160Hz/400Hz/1kHz/2.5kHz/6.3KHz/16KHz). Listening Position selector (4 Mode: Front Left/Front Right/Front/All). You can adjust 7bands EQ Frequency (63Hz/160Hz/400Hz/1kHz/2.5kHz/6.3KHz/16KHz) individual. Each of the 7 EQ bands can be adjusted +/-12dB.You can create 4 EQ curves to be stored in memory (1-4). I cleaned up and readjust CD optical Lenz in order to optimally read many different CDs and CD-Rs in top condition. CDs and CD-Rs immediately after loaded a CD disc and FF or REW songs from the beginning of the songs to the end of song in timely manner. However it is not a CD-R compatible model thus I cannot guarantee it reads all your CD-Rs (Burned CD Disc).
