ZVOXSoundBase 220/320/420 Connection Guide
The ZVOX SoundBase 220, 320 and 420 models have both 
analog and digital signal inputs. Internally, the SoundBase  
220, 320 and 420 systems use high-quality analog audio 
Important Notes: 
1
It is not necessary to connect to a TV 
to use a ZVOX SoundBase system. 
Any cable box, satellite TV box, DVD 
or Blu-ray player and other external 
video source used with a TV has its 
own analog audio output. You can 
connect analog audio outputs from 
up to three separate sources directly 
to the SoundBase. So even if your 
TV does not have a compatible audio 
output for a SoundBase 220, 320 
and 420 system, you can still enjoy  
high-quality surround sound.
processing. In the majority of cases, the analog audio  
signal output from a TV is the correct output to use  
with a SoundBase 220, 320 and 420 system.
Here are the audio signal output types 
found on recently manufactured TV models:
Analog Stereo Minijack
Audio signal cable needed: Stereo minijack at one 
end and a pair of RCA plugs at the other end.
Analog Left and Right RCA phono jacks
Audio signal cable needed: A pair of RCA Phono 
plugs at each end.
Optical Digital jack

It is always possible to congure 
the digital audio output of a DVD or 
Blu-ray player to PCM format digital 
audio, which is compatible with any 
digital input on a SoundBase 220,  
320 and 420 system.
