Functional Verication and Test Procedure
Digital inputs and RCA output level check
Check each digital input gives 2.1V at the RCA output with a 0dFS 1kHz tone input.
XLR output level check
Using one of the digital inputs check XLR output level is 4.2V with a 0dFS 1kHztone input.
THD+N RCA outputs
Using one of the digital inputs check THD+N is 0.001% at the RCA output terminals with a 0dFS 1kHz tone input.
Frequency Response RCA outputs
Using a xdBFS 20-22kHz sweep tone applied to one digital input check output level at RCAs.
The output level should stay between -0.5dB and +0.2dB from 20-20kHz with respect to 2.1V reference level.
Mute Check
• Apply a signal to one of the digital inputs.
• Check there is an output signal on RCA, XLR and digital outputs.
• Mute the unit using remote control and check the output signal disappears.
• Unmute the unit with the remote control and check that the output signal returns.
Check RS232
• Connect RS232 to unit.
• Open the ST60 console.
• In the connection tab select the correct com port and set baud rate to 38400.
• In the RS232 command tab send a mute command (make sure RS232 tick box is checked).
• Check the unit is muted, display should indicate the unit is muted or use audio outputs.
Check Ethernet
• Connect Ethernet cable to unit.
• In RS232 command tab request IP address (make sure RS232 tick box is checked) and make a note of IP
address.
• Enter IP address in connection tab.
• In RS232 command tab send an unmute command (make sure TCPIP tick box is checked not RS232).
• Check the unit is not muted, display should indicate the unit is not muted or useaudio outputs.
Check Airplay
• Connect Ethernet cable to unit.
• Play a track in iTunes and airplay to the ST60, make sure track is played back via RCA or XLR output.
• Check playback from digital output.
Check USB playback
• Plug in USB stick to ST60 with an audio test track.
• Use remote control to navigate to the USB input and play a track.
• Make sure track is played back via RCA or XLR output.
Check GoogleCast
• Remove Ethernet cable
• Setup unit up via Googlecast
Check Display
• Using engineering menu run display test. Look for dead pixels.
• To access engineering menu select Digital 1 input. Press and hold encoder for > 3s, on release the
engineering menu will be displayed.
Check front panel controls
• Check encoder works.
• Check input, play and menu button work.
