INT-150 Owners Manual

Choose either XLR or RCA inputs.  If  you run both at once on a single 
input from different components, the sound is not likely to be optimal, but 
it shouldn’t cause damage anywhere.
 
Now that the source components and loudspeakers are connected into 
the amplifier; plug the power cord back into the wall, and turn on the rear 
power switch.

Push the front panel power button to activate the amplifier and turn the 
volume control down (counter clock-wise).  The front panel display should 
now be illuminated.

The controls on the front of  the Pass Labs integrated amplifier should be 
intuitive.  You should however understand that the volume control is always 
active and over rides the mute control.  Meaning that if  at some point you 
activate the mute control you can un-mute the amplifier by either pushing 
the mute control a second time or by either advancing or retarding the 
volume control knob. 

The hand remote has some additional convenience features that the front 
panel does not.  Balance from the remote raises or lowers the speaker 
volume levels relative to each other.  Display provides a choice of  normal 
luminance, reduced luminance or display off.  In the display “off ” mode 
the display will be normally dark, yet will provide reduced luminance 
for several seconds any time a control function on either the remote or 
integrated amplifier front panel are activated.

Please note:  The hand remote is common to several Pass Labs products, 
not all of  the functions on this remote are applicable to your integrated 
amplifier.  Input 5, tape loop, pass through and external amp on are not 
applicable to the INT-150, integrated amplifier.

The hand remote has two (2) AAA batteries that can be replaced after the 
back cover from the remote has been removed.   These batteries will need 
to be changed occasionally.

If  you are not comfortable removing the rear cover of  the remote and 
changing batteries, have your dealer change them for you.  Batteries may 
explode if  exposed to excessive heat, never leave your remote or any 
battery powered device in direct sunlight or exposed to excessive heat 
sources.

With any luck, you can now enter that blissful state of  musical nirvana, and 
we won’t expect you back for a while.

It’s always possible that something may go wrong.  If  so, don’t get excited.  
We know It’s really aggravating when a product doesn’t work, but it will get 
fixed, and often it’s something really simple.  

You are ready to play music
