Regulatory Notices
EMI NOTICE
This equipment has been tested and found to comply with the limits for a Class A digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable
protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction manual, may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause
harmful interference in which case the user will be required to correct the interference at his
own expense.
Canadian Department of Communications compliance statement:
This equipment does not exceed Class A limits per radio noise emissions for digital apparatus
set out in the Radio Interference Regulation of the Canadian Department of Communications.
Operation in a residential area may cause unacceptable interference to radio and TV reception
requiring the owner or operator to take whatever steps are necessary to correct the interference.
Avis de conformite aux normes du ministere des Communications du Canada:
Cet equipment ne depasse pas les limites de Classe A D'emission de bruits radioelectriques
pour les appareils numeriques telles que perscrites par le Reglement sur le brouillage
radioelectrique etabli par le ministere des Communications du Canada. L'exploitation faite en
milieu residentiel peut entrainer le brouillage des receptions radio et television, ce qui olbigerait
le proprietaire ou l'operateur a prendre les dispositions necessaires pour en eliminer les causes.

1.2 Front Panel Controls and Indicators
Figure 1: Front Panel Controls and Indicators
The front panel contains the following controls and indicators for operating AP20.
Power button: Turns the unit on and off
LCD/Touch Screen: Displays theater system configuration and status and allows
configuration changes. Most selections can be made by touching the screen with your finger
or by using a stylus.
The LCD screen operates in two modes:
oHome screen. The projectionist can select formats and mute volume from this screen.
They can also change the monitor volume and execute manual automation commands
via the popup windows. During playback, the screen displays information about the
content currently being played.
oSetup mode. In menu mode, the screen displays menus for viewing and adjusting
operational settings by the cinema technician. The projectionist does not need to enter
these menus.
Adjustment knob:Used for fader control and parameter adjustments. On the Home screen,
this knob adjusts the fader level. However, it is used within the setup screens to adjust values,
EQ filter faders, and other values. When the setup screen contains many controls, first set the
focus by touching the control on the display. Then move the knob clockwise to increase the
value, or counterclockwise to decrease the value.
USB port: Use for software updates and loading and saving of configurations. See topic
Update System Software From USB Device on page 54 for more details.

Figure 4. Home Screen
If no messages appear on the touch screen after you have turned on the power switch, check
the following:
Is the power to the sound rack on? Has the circuit breaker to the audio rack been tripped?
Is the power cable connected?
Is the front panel power switch lighted?
Navigating through the Menus
Since the AP20 is equipped with a touch screen display, you can navigate easily through the menus by
touching any button with your finger. A non-abrasive stylus that won’t scratch the screen can also be
used if you prefer.
In all screens but the Home screen, you will be presented with a button menu along the bottom of the
screen. This menu will take you to any other screen within the menu structure with a few touches of your
finger.

1.5 Troubleshooting (Operation)
The following table provides troubleshooting data for the AP20.
PROBLEM SOLUTION
AP20 will not power ON Press and release the power button on the front panel. If the
unit will not power up, be sure the rear panel power switch is
ON and the unit is plugged into a working AC outlet protected
by a surge protector. See Powering ON the AP20 Processor,
page 16.
If the AP20 is mounted in a rack and a breaker is used for the
rack, make sure the breaker is ON.
Verify the surge protector is powered and is working.
Try changing the AP20 power cord.
If power is getting to the AP20 but it still will not power ON,
maybe the fuse above the AC In connector (on the rear panel)
is blown. Call a theater technician to check it.
AP20 front panel display is too
dim
The front panel display automatically dims when not touched for
a few seconds. Gently touch the display screen to brighten it.
No sound in auditorium On the front panel display, verify the Mute button is not muted.
If it is muted, touch it to unmute it.
Be sure the fader level is not zero (0) or red. If it is zero, then
turn the knob to increase the volume. If it is red, then unmute
the AP20 by touching the Muted button.
Verify the AP20 is in the correct format.
Volume is too low or high in the
auditorium
Turn the fader knob to achieve proper volume.
Volume is too low or high in the
booth
Touch the Monitor button to open the Monitor window, then
touch the + or – to adjust the monitor volume.
No sound in booth Verify the Monitor is not muted (red). To unmute, touch the
Monitor button, then touch the red Muted button.
Verify a powered speaker is connected to the AP20 rear panel.
Verify the speaker’s power is ON.
Adjust the monitor volume (see previous entry).
Wrong sound in auditorium Verify the AP20 is in correct format. (The current format is
highlighted in the bottom row of the display.) Touch a different
format to select. If the format you want is not listed, it has not
been set up – contact your theater technician.

A note about Digital Out
Most theaters use ANALOG OUT because there are no amplifiers (at this time) that take
digital audio inputs. It is possible to have DIGITAL IN to the AP20 and ANALOG OUT.
DIGITAL OUT capability may be implemented only in some high-tech recording studios,
mixing stages, etc.
2.5 Chassis Rack Mounting and Connection
The AP20 chassis requires 3U of standard rack space for proper mounting.
Caution: Because power line surges can damage the AP20, we require the use of a
properly functioning computer-grade surge /spike suppressor. We also recommend using an
uninterruptible power supply (UPS).
1. Install the AP20 into the audio rack, securing it properly with rack screws.
2. Connect the AP20 to other equipment (see appendices: A Connector Pin-outs, B Interface
Wiring Diagrams, and C AP20 Wiring and Block Diagrams).
3. Connect the supplied power cable between the AP20 unit and the AC mains source.
2.5.1 Rack Mount Recommendations
Follow these recommendations if the AP20 unit will be installed in a closed or multi-unit rack assembly.
Determine the maximum and ambient temperatures within the rack, since they may be greater
than the maximum and ambient temperatures in the room. The maximum temperature for the
equipment in a closed or multi-rack assembly is 40°C (104F°)
Ensure adequate airflow for cooling purposes on all sides of rack-mounted equipment. Make
sure that the ventilation fan is not blocked.
Check nameplate ratings to ensure there is no overloading of supply circuits that could have
an effect on over-current protection and supply wiring.
Maintain reliable grounding of the equipment. Give particular attention to supply connections
when connecting to power strips, rather than direct connections to the branch circuit.
Using a properly functioning quality surge protector is required to protect the unit. Using an
uninterruptible power supply is also recommended.
2.5.2 Power Supply
The AP20 power supply automatically switches itself to accommodate AC input between 110 VAC and
220 VAC.

2.6 About Formats
The AP20 facilitates the process of creating customized audio formats, in addition to providing
a set of pre-build formats that are ready to use.
The buttons along the bottom of the AP20 Home screen are the default formats or formats that
have been created by the installation technician for a particular application. Each format
consists of a set of discrete settings: an Input Source, Format Options, EQ settings, and Channel
Profile, as illustrated below (Figure 12).
System setup, Network and Automation are global settings that affect all formats.

Options, EQ Setup, and Channel Profile.
