REAR PANEL
DIRECT OUTPUT – An XLR balanced direct output is provided for connection to a PA system or directly into a
recording studio console or D/A converter. This signal comes directly from the Tube buffered input stage to the
Direct Output. The Direct Out signal may be switched between mic and line level, pre and post EQ, and the audio
signal ground may be connected or lifted from pin 1 to eliminate hum due to ground loops. This output is fully
protected against 48 volt phantom power and may be used for driving microphone lines of over 300 feet without
problems.
TUNER OUTPUT – The Streamliner™ 900 is equipped with a fully isolated Tuner Output. This jack is buffered right
off of the input jack and before any preamp tubes. This output may also be used to drive a separate direct box or
high-impedance recording device where an uncolored signal path is desired. The Tuner Output remains active when
the amplier is muted, allowing for silent tuning on stage.
AUX INPUT – A 1/4” unbalanced line level aux. input is provided that sums directly to the main output bus,
controlled by the master volume control. This input is ideal for practicing with recorded tracks from a CD player,
IPOD, or MP-3 player. This input is a tip-ring-sleeve type jack with built-in summing resistors that sum left and right
signals when used with a stereo cable. This input will also work with a mono tip-sleeve plug. Adjust the level of the
playback source to balance with the bass guitar’s volume.
EFFECTS LOOP – A rear panel effects loop (SEND and RECEIVE jacks) is provided for connecting line level
“serial” outboard devices such as compressors and may also be used for parallel type outboard devices (delays,
reverbs, harmonizers, octavers etc.) by using the mix control located on the outboard device. This loop is located
right before the Master Volume control and is also intended as a Preamp Out / Power Amp In connection for
possible “chaining” of ampliers in a Master / Slave conguration. The effects “loop” contains a “normal switch” in
the receive jack that interrupts the signal path when a plug is inserted into the receive jack. The send jack may be
used as a Post-EQ Aux. output without breaking the signal path. The Master Volume control adjusts the volume of
any signal input through the Effects Return jack.
HEADPHONE OUT – A 1/4” TRS jack is provided for connection to headphones for silent practice use. The speaker
output is not automatically muted. The speaker outputs should be manually disconnected. It is never an issue
for the Streamliner™ to be used without a speaker load connected. Do not connect this output to anything but
headphones.
