CD HI-FI MINI SYSTEM
Built-in Dock for Direct Digital Connection of
®
/iPhone
®
iPod
In addition to handling CDs, the CS-345 features a 
top-loading dock for iPod/iPhone. This direct digital 
connection allows you to access podcasts and music in a 
variety of audio for mats. As the audio signals are 
transpor ted in digital for m, rather than analog, there is 
much less possibility of signal degr adation. Tracks on your 
iPod/iPhone can be browsed, skipped, and shuffled using the 
accompanying remote control.
Efficient Digital Amplifier Circuitry for Clean 
Audio Signals 
The CS-345 employs digital amplifier circuitry to extract a 
noise-free signal from digital audio sources. Whether it’s on 
a standard CD or in a compressed MP3 file stored on CD, 
your music will sound clearer than ever. Because digital 
amplifiers can conver t power with very high levels of 
efficiency, much less energy is wasted as heat. With no need 
for a bulky heat sink, the amplifier design can be smaller and 
lighter. Hence, the CS-345 can provide room-filling power 
that belies its modest size.
Active Bass Control 
At quiet volume levels, human hear ing becomes less 
sensitive to sounds at the upper and lower ends of the 
audible spectr um. To compensate for the perceived loss of 
bass sounds at lower volumes, the CS-345 incor porates 
Onkyo’s proprietar y Active Bass Control. This function 
maintains an optimal balance of low-frequency sounds by 
making automatic, real-time adjustments in line with the 
playback volume. Listener s are able to enjoy smooth and 
natural-sounding bass at any volume level. 
Compact Yet Solid Two-Way Bass-Reflex Speakers  
The CS-345 includes a pair of bass-reflex speakers 
incorporating a two-way design for clearer separation of 
highs and lows. Both cabinets feature a powerful 4” (10 cm) 
woofer and a balanced-dome tweeter. The speaker s are 
constructed from dur able MDF (Medium Density 
Fiberboard), rather than regular fiberboard. This higherquality mater ial enhances sound quality and prevents the 
finish from rolling back, cracking, or splitting.
