Manley Labs 300B Stereo Amplifier User Manual


 
REAR PANEL
A - MAINS FUSE - Replace with 2A SLO-BLO fuse only.
B - IEC MAINS SOCKET - Standard IEC mains socket (120/240 VAC as indicated)
C - LINE OUTPUTS - Main left and right outputs driven by 300B's. Connect these to your
power amplifier inputs when the amps are off. These 2 pairs of outputs
are electrically identical and a bi-amp set-up is one application.
D - RECORD OUTPUT - Set at input line stage level. These normally are connected to a tape
recorders inputs. The signal is "picked off" the input selector and before
the volume control. It is a good idea to disconnect any wires connected to
these jacks when not recording to prevent losses of extra loading and
cable capacitance from affecting best performance possible.
E - VIDEO INPUT - Audio actually, from a VCR or Laser Disc player's audio outputs.
F - TUNER INPUT - Connect your tuner outputs here. Another good input for #1 VCR.
G - TAPE INPUT - Tape machine outputs can be connected here. Be very careful - If the tape
machine inputs are connected to the preamplifier TAPE OUTPUT's and
the preamp is switched to TAPE and the tape machine is set to monitor
"INPUT" or you start to record - The dreaded squeel and howl of
feedback. One quick "cure" is not to select "TAPE" on the rotary input
selector if these other conditions are met. No "tape loop" switch.
H - CD - Plug in your audio outputs from your CD player or "D to A Converter" here.
I - AUX - Plux your Aux in here -What is an Aux?. It stands for Auxilliary and basically
means "extra", so this is just an extra input for any other source that we
didn't label or you have two of. Any of the input jacks can be used with
any hi-fi RCA outputs and they are electrically identical and only differ
in how we labelled them.
J - GROUND TERMINAL - This is a "Chassis Ground" Terminal for gear that has those
single wires with a spade lug that is meant to be "tied to ground". Helps to reduce hum.
