Congratulations on your purchase of an
Altec Lansing 1662A mic/line mixer, a
professional, studio quality solution to everday
mixing needs. The 1662A features six mic/line
inputs with mic input pad, TRS insert points, and
+48V phantom power. Each channel has up to
60dB input gain, separate treble and bass
controls, level, and an output channel assign
switch for sending any channel to either or both
outputs. Stereo sum inputs are provided for
adding typical program audio sources from DVD,
CD, tape, etc. A full 11 segment LED array
indicates stereo output level.
they were carefully designed to reduce to
minimum the possibility of transportation
damage should the unit again require packing
and shipping. In the event that damage has
occurred, immediately notify your dealer so that
a written claim to cover the damages can be
initiated.
The right to any claim against a public
carrier can be forfeited if the carrier is not
notified promptly and if the shipping carton and
packing materials are not available for
inspection by the carrier. Save all packing
materials until the claim has been settled.
Mic/line inputs and main outputs use
Euroblock connectors, allowing bare wire to be
easily connected to the mixer without soldering.
The 1662A mixer uses professional quality 16mm
metal shaft potentiometers for greater accuracy
and long life.

As a part of our system of quality control,
every Altec Lansing product is carefully
inspected before leaving the factory to ensure
flawless appearance. After unpacking, please
inspect for any physical damage. Save the
shipping carton and all packing materials , as
The lightning flash with arrowhead
symbol, within an equilateral triangle, is intended to alert the user
to the presence of uninsulated
"dangerous voltage" within the
product's enclosure that may be of
sufficient magnitude to constitute
a risk of electric shock to persons.
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE
COVER. NO USER SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.
TO REDUCE THE RISK OF FIRE OR ELECTRICAL SHOCK,
DO NOT EXPOSE THIS APPlIANCE TO RAIN OR MOISTURE.

The 1662A mixer will perform normally
from 93 to 125 volts AC, 50-60Hz (some export
models are wired for 240 Volts and are labeled
accordingly). Use only properly grounded AC
receptacles. To reduce the risk of ground loop
hum, use a central point for system AC power
distribution. In the event of an internal fuse
failure, refer this unit to a qualified service
technician for fuse replacement using only the
same type fuse, 0.5A Bussman AGC-1/2 or
equivalent. Power consumption is less than 20
watts.
The exclamation point within an
eqilateral triangle is intended to
alert the user to the presence of
important operating and maintenance instructions in the literature
accompanying the device.
TO REDUCE THE RISK OF FIRE, REPLACE ONLY WITH SAME
TYPE FUSE. REFER REPLACEMENT TO QUALIFIED SERVICE
PERSONNEL.
WARNING:
THIS APPARATUS MUST BE EARTHED

This three position switch sets the
operating level of the input preamp to +20db,
+40dB, or +60dB. Best signal to noise ratio is
obtained with higher gain settings. It is
therefore desirable to set the gain switch as high
as possible while still leaving 20dB of headroom
for signal peaks. Line level inputs will likely use
a setting of +20dB, while mic inputs generally
require a setting of +40dB for close mic
applications, and +60dB for quieter signals. If a
channel's clip LED is blinking, first turn down
that channel's level control. If the clip LED is
still flashing, turn down the input gain.

Input Clip LEDs are peak sensitive and
monitor all critical points within the input
channel. The clip LED turns on whenever any
portion of the audio path within the input
channel reaches a level 3 dB below actual
clipping. Clipping in the 1662A occurs at +23dB.

These controls are used for broad EQ
changes to each input channel. Channel EQ
consists of a high shelf control (treble) at 8KHz,
and a 90Hz low shelf control (bass). EQ boost or
cut is ±12dB at these frequencies.

This knob adjusts the level of each
channel. If a channel's level control is always
turned up to 9 or more, try increasing the gain
first. Conversely, if the level control is
consistently turned down to 1 or less, decrease
the gain setting first. Remember that the gain
setting should be set as high as possible while
still allowing 20dB of headroom.
