6. Balanced Input
Balanced line level signals connect to the (+), (–), and (G) terminals. Note if you are connecting an
unbalanced line level input, tie (short) the (G) and (–) terminals together with an insulated jumper
wire.
7. Line In
The Line In connector is useful for receiving a -6dBV mono unbalanced line level signal from a
playback system such as a CD player.
8. Line Out
Line Out connector is useful for providing unbalanced line level signal to another amplifier or other
external device.
9. Loudness Contour EQ
This switch, when in the ON position, provides +4dB of boost at 100Hz and 8kHz. Use of this EQ is
suggested to enhance music playback at low levels.
10. Output Terminal Strip
For loudspeaker connections, connect as follows or proceed to the setup section for typical wiring
schemes.
COM - Speaker common or negative connection
4Ω - Connect to direct coupled loudspeakers
70V - Connect to transformer coupled, 70.7V loudspeakers with a total load impedance of 83Ω
100V - Connect to transformer coupled, 100V loudspeakers with a total load impedance of 167Ω
11. IEC AC Receptacle
Prior to connecting a grounded power cord the proper selection of the AC Line switch and fuse must be
made. For 120VAC use the 1.6A/250V fuse and for 230~240VAC use the 1A250V fuse.

OWNER'S MANUAL
WIRING THE PA601
Speaker Outputs - Use 2 conductor unshielded wire of the appropriate gauge. If you are unsure about
this, contact Atlas Sound Tech Support at 1-800-876-3333. Make sure you know how many speakers you
need and what tap value you intend to use.
Balanced Input - Use 2 conductor w/shield for low level signals (20-22 gauge is best). Maintain the
proper polarity, + to +, – to –, and shield to ground.
Unbalanced Inputs and Outputs - Pre-made RCA cables can be purchased from vendors to simplify
interconnection to external devices.
SECURITY COVER OPTION
In order to prevent unauthorized operation of the PA601, optional security covers are available which take
the place of the front panel knob. After the PA601 has been installed and is operating as desired, grasp
the front panel knob and pull straight out from the front panel. Replace the knob with a security cover,
Atlas part number AAVCC-5.
