Description
The AAM™1662 is a high quality, commercial grade analog audio mixer.
Designed for desktop or rack mounted installation, the AAM 1662 represents
the latest, state-of-the-art technology in analog circuit design.
The heart of the AAM 1662 is centered around its extensive mix bus architecture which includes fourteen separate audio buses. Driving these buses
are four different types of input assemblies that offer extremely high performance, versatility and value for most fixed audio applications.
The AAM 1662 includes a versatile input complement. Choices include two
full-featured microphone or line level inputs, six normal mic/line inputs, six
mic/dual sum line inputs and two mic/line stereo inputs. All microphone
inputs include 48 V phantom power and studio grade microphone preamplifiers.
The input assign functionality is very rich, and includes multiple options for
sending microphone, single line, dual line or stereo line signals to the output
buses. Multiple options for routing and distributing input signals make the
AAM 1662 one of the most flexible audio mixers on the market today.
The AAM 1662 is equally impressive on the output side. The fourteen discreet mixing buses coupled with eleven output connectors makes this unit
even more versatile. The main L/R and Aux 1/2 outputs are fully balanced, as
is the summed mono output, derived from the L/R buses.
A full monitoring section provides selectable inputs for headphones or control room outputs. Inputs for these outputs are selectable from any of the
balanced output buses as well as a separate 2-track input that simultaneously feeds the L/R bus. A full-featured PFL cue mix rounds out this section.
Overall, the AAM 1662 is a powerful, easy-to-use, high performance product.
Sonic performance is well beyond what is to be expected in this price range,
and the wealth of features, busing and routing make the AAM 1662 perfect
for most audio applications where multiple inputs and outputs are required.
With a clean package that is equally suited for desktop or rack mounted
applications, the AAM 1662 looks as good as it sounds. A rear panel connector bay, removable IEC power connector and several rear panel controls
make this unit easy to implement in fixed installation applications.

This manual is written to provide as much practical information as possible
about the AAM
™
1662 audio mixer. Primarily written for the systems inte-
grator, there is also much here that can benefit the end user.
In order to present a clear, comprehensive and logical summary of the product’s features, this manual is written around the AAM 1662’s architecture.
Essentially, an audio mixer is a collection of inputs and outputs, with several
audio buses in between. If you look carefully at the master signal flow diagram on pages 32-33, you can see this clearly.
This manual presents the features of the AAM 1662 as they relate to the signal flow. Each section of features is accompanied by the signal flow diagram
for that section. Each part of the signal flow is described and graphics of
corresponding panel features are included for each section as well.
It is very important to understand the relationship of signal flow components and how they relate to their front and rear panel counterparts. But
unlike other mixer or console manuals, this book is not a collection of simple
knob, button and connector labels. The objective here is to present the complete mixer. Without understanding signal flow, this is impossible.
This manual is broken into sections for each block of signal flow. These sections include:
• Super channel inputs (Channels 1 & 2).
• Input channels with direct outputs included (Channels 3-8).
• Input channels with dual line inputs included (Channels 9-14).
•
Input channels with stereo inputs included (Channels 15-16).
•
Main outputs (Left, Right, Mono)
•
Main group outputs (Group 1-4).
• “Bonus” group outputs (Group 5-6).
• Balanced aux outputs (Aux 1-2).
• Unbalanced aux outputs (Aux 3-6).
• Master (Headphones, PFL, Tape I/O and CR).
In this way, a complete primer of the mixer’s signal flow and accompanying
functionality is presented. At the same time, the manuals organization and
presentation style facilitates itself as an excellent reference book for quick
answers to common field questions.
All balanced XLR connections follow the AES standard. This means that pin
2 carries the positive side of the signal, pin 1 carries the negative side of the
signal and pin 1 is terminated to the shield, or chassis ground.

Installation
For desktop applications, the AAM 1662 can be installed just about anywhere there is good air flow and normal indoor conditions. Please refer to
the cautions for exterior environments on page 3 of this manual.
For rack mounting, the AAM 1662 is designed to be installed in commercial
grade, EIA electronic equipment racks only. Installing this unit in non-EIA
racks or in other configurations is not recommended. Failure to install this
product in the proper enclosure may void your warranty.
The AAM 1662 is convection cooled, and care should be taken not to block
the air intake or exhaust path located on the sides of the unit. When
installed in EIA racks, the AAM 1662 can be installed adjacent to other
equipment without additional venting; however, it is recommended that
common sense be applied to large installations where multiple units are
mounted in a single rack. It is generally accepted that a ratio of one rack
vents for every two audio components is a good rule of thumb that usually
provides adequate performance. In installations where adverse conditions
exist, and room temperatures are likely to rise, additional vents should be
installed.
The AAM 1662 can be installed into any EIA rack with an internal depth
clearance of 18" or more. This will allow plenty of space for the unit, and its
associated wiring harness. When dressing off wiring harnesses, take care
and leave plenty of room for bends and terminations. Allow the cable to
progress naturally between components. Creating tightly wrapped wire
bundles can cause broken solder joints and defective terminations.
To successfully install your new AAM 1662, and perform the testing examples contained in this manual, you will need the following components:
•
One AAM 1662 mixer
•
A high quality balanced microphone and cable
•
A stereo line level audio source with connecting cables (CD player)
• A two-channel power amplifier
• Two high quality loudspeakers
In most audio systems, the minimum configuration consists of an input signal, gain amplifiers, distribution/routing circuits, signal processing, power
amplification and output transducers. Depending on your system, this may
consist of several products. When using the AAM 1662, at least one signal
source and output system are required to configure the minimum system.
Of course, most systems will include more inputs and outputs, but this is the
basic configuration required to work with this manual.
The use of high quality, audio cables is required to successfully implement
the AAM 1662 with professional audio systems.
