Install Instructions For:

SB335

The SB335 is a 2 or 3 channel amplifier with Dolby Digital decoding. It is designed to be used with either an analog or digital input from a TV or other audio source. With a digital input it automatically senses Dolby Digital and PCM and switches modes. The SB335 takes the input signal from an audio source, decodes it and outputs either a 2 or 3 channel amplified signal to a sound bar or set of speakers. When set in the 2 channel mode it will take a stereo or multi-channel signal and mix it down to 2 output channels (left and right). When set in the 3 channel mode it will take a stereo or multi-channel signal and mix it into 3 output channels (left, right and center). In either mode there is a sub out option.

When used in place of internal TV speakers, change the TV's audio setting to external speakers. Teach the SB335 the TV's volume codes and it seamlessly operates with no additional remotes.

There are two modes the SB335 can operate in; Standby and Sleep. Setting the SB335 in the standby mode disables the auto-on input signal sensing. In this mode the SB335 can only be turned on by pressing the Volume control On/Off switch or through RS232 control.

Setting the SB335 in the sleep mode enables auto-on input signal sensing and will turn the SB335 on when there is a signal present and will automatically turn off when there is no signal for 5-7 minutes.

Note: The SB335 goes into standby mode 5 minutes after it stops sensing a signal provided the amp is set to standby mode.

The SB335 will be switched into networked sleep mode in 5 minutes after it stops sensing a Bluetooth or wired audio signal provided the amp is set in sleep mode.

Setting the operating mode:
