CAL COLUMN ARRAY LOUDSPEAKER
The CAL™ steerable column array loudspeaker combines
over three decades of technological innovation and
advanced research into the laws of physics and digital signal
processing to achieve unprecedented accuracy in sound
reproduction. Designed primarily for vocal reproduction in
fixed installations, the self-powered CAL offers vertical
beam spreads as narrow as 5 degrees and as wide as
30 degrees that can be digitally steered up or down by
30 degrees. CAL’s beam steering takes the practice of
directing sound to the next level, and with a smart, lean profile, CAL sets the standard for high-quality sound installations.

CHAPTER 1: INTRODUCTION
!
CAL is available in three models, each providing a different
output level — up to a maximum peak SPL of 106 dB at
90 meters with CAL 96 — over an operating frequency range
of 100 Hz to 16 kHz. Providing a horizontal coverage of
120 degrees, as well as the flexibility of vertical beam steering, a single unobtrusive CAL delivers clear vocal reproduction over a large area while minimizing undesirable
reflections.
Discrete onboard Class D amplifier channels, processed by
sophisticated algorithms, power each driver and tweeter. The
amplitude and phase responses of each driver are engineered to produce interactions that yield the desired vertical
spread. Controlling each element individually yields greater
flexibility and precision than other beam steering systems
that control modules comprised of multiple drivers.
The accuracy of CAL’s vertical steering allows system
designers to pinpoint coverage, even when mounting options
in a venue do not allow for physically aiming a loudspeaker
toward a coverage area. CAL 96 and CAL 64 include beam
splits that can be configured to fit the application, for example, to avoid hitting a reflective balcony surface. To meet the
high intelligibility requirement for vocal reproduction, CAL has
been engineered to maintain accurate beam steering up to
10 kHz, well beyond the benchmark of 4 kHz used in traditional single-driver loudspeakers.
CAL loudspeakers include two AVB-enabled Ethernet ports
for receiving AVB audio streams as source signals. The ports
also provide computer control of CAL via Meyer Sound’s
Compass
®
control software, allowing beam control and
RMS™ real-time monitoring of each loudspeaker on the network.
CAL comes standard with adjustable mounting brackets for
installation on walls or columns. The low-profile aluminum
enclosure is available in white, black, and custom colors,
allowing it to blend easily into any background. Weather protection permits outdoor installations in most environments.
CAL INSTALLATION OVERVIEW

CAL loudspeakers combine advanced loudspeaker technology with equally advanced power capabilities. Understanding voltage and current requirements, as well as electrical
safety issues, is critical to CAL’s safe operation.
AC INPUT CONNECTOR
CAL receives AC power from its 3-pole powerCON 20 locking connector. Located on the unit’s rear panel, the connector is rated at 20 A and provides locking connections to
avoid accidental disconnections. A 10-foot AC power cable,
rated at 15 amps, is included with each CAL loudspeaker.
CAL AC Input Connector
CAL loudspeakers require a grounded outlet. To operate
safely and effectively, it is extremely important that the entire
system be properly grounded.
If you replace the included AC power cable, make sure to
use a cable that is wired correctly and equipped with the
appropriate power plug (on the other end) for the area in
which you will operate the unit.
WIRING FOR AC CONNECTIONS
CAL loudspeakers require a grounded outlet. To operate
safely and effectively, it is extremely important that the entire
system be properly grounded.
AC Cable Wiring Scheme
When wiring international or special-purpose AC power
cables and connectors, use the following wiring scheme:
■ Connect the blue wire to the black terminal, or the termi-
nal marked with an N.
■ Connect the brown wire to the red terminal, or the termi-
nal marked with an L.
■ Connect the yellow and green wire to the green (or green
and yellow) terminal, or the terminal marked with an E.
CAUTION: When creating AC power cables, it
is important to preserve AC line polarity and
connect the earth ground on both ends of the cable.
CAL requires a grounded connection. Always use a
grounded outlet and plug. It is extremely important
that the system be properly grounded in order to
operate safely and properly. Do not ground-lift the AC
cable.

CHAPTER 2: POWER REQUIREMENTS

!
CAL VOLTAGE REQUIREMENTS
CAL operates safely and continuously when the AC voltage
stays within 100–265 V AC at 50 or 60 Hz. The loudspeaker
can withstand continuous voltages up to 265 V and allows
any combination of voltage to GND (neutral-line-ground or
line-line-ground).
If the voltage drops below 90 V (brownout), CAL uses stored
power to continue operating temporarily; the loudspeaker
shuts down if the voltage does not rise above the low
boundary before the stored power is used.
If the voltage rises above 265 V, the power supply immediately shuts off to prevent damage to the unit.
If CAL shuts down due to either low or high voltage, its
power supply automatically powers up again after three seconds, so long as the voltage has returned to its normal operating window. If CAL does not power up after 10 seconds,
remove AC power immediately and contact Meyer Sound
Technical Support.
CAUTION: The power source for CAL should
always operate within the required voltage
range, at least a few volts from the upper and lower
ranges. This will ensure that AC voltage variations
from the service entry — or peak voltage drops due
to cable runs — will not cause the loudspeaker’s
amplifiers to cycle on and off or cause damage to the
power supply.
Powering Up CAL Loudspeakers
When AC power is applied to CAL, its Intelligent AC™ power
supply automatically selects the correct operating voltage,
allowing it to be used internationally without manually setting
voltage switches. In addition, Intelligent AC provides softstart power up, eliminating high inrush currents; suppresses
high-voltage transients up to several kilovolts; filters common mode and differential mode radio frequencies (EMI);
and sustains operation temporarily during low-voltage periods.
When powering up CAL, the following startup events occur
over several seconds.
1. Audio output is muted.
2. Voltage is detected and the power supply mode is automatically adjusted as necessary. The power supply
ramps up.
3. After the power up sequence and system check have
completed, the ON/Status LED turns solid green, indicating the loudspeaker is ready to reproduce audio.
CAUTION: If the ON/Status LED does not turn
solid green after powering up and audio is
muted, the loudspeaker has encountered a failure
and may need to be serviced. Contact Meyer Sound
Technical Support.
NOTE: When voltage fluctuates within CAL’s
operating range, automatic tap selection stabilizes the operating voltage. This tap selection is
instantaneous with no audible artifacts.
NOTE: Since CAL does not require a dedicated
neutral line, and it can tolerate elevated voltages from the ground line, it can be connected to
line-line terminals in 120 V, 3-phase Wye systems.
This results in 208 V AC between lines (nominal) and
therefore draws less current than when using 120 V
AC (line-neutral). Make sure that the voltage remains
within CAL’s recommended operating window
(100-264 V AC). The ground line must always be used
for safety reasons and the line-to-ground voltage
should never exceed 264 V AC (typically 120 V AC
from line-to-ground).
CAL CURRENT REQUIREMENTS
The current draw for CAL is dynamic and fluctuates as operating levels change. Since different cables and circuit breakers heat up at varying rates, it is important to understand the
following types of current ratings and how they affect circuit
breaker and cable specifications.
■ Idle Current — The maximum rms current during idle
periods.
■ Maximum Long-Term Continuous Current — The
maximum rms current during a period of at least 10 seconds. The Maximum Long-Term Continuous Current is
used to calculate temperature increases for cables, to
ensure that cable sizes and gauges conform to electrical
code standards. The current rating is also used as a rating for slow-reacting thermal breakers.
12
Page 13
CAL OPERATING INSTRUCTIONS
Earth ground
Chassis ground
■ Burst Current — The maximum rms current during a
period of around one second. The Burst Current is used
as a rating for magnetic breakers. It is also used for calculating the peak voltage drop in long AC cable runs
according to the following formula:
V pk (drop) = I pk x R (cable total)
The Burst Current can also be used to calculate the AC
looping capability of CAL.
■ Ultimate Short-Term Peak Current — A rating for fast-
reacting magnetic breakers.
■ Inrush Current — The spike of initial current encoun-
tered when powering on.
You can use the following table as a guide for selecting
cable gauges and circuit breaker ratings for the system’s
operating voltage.

ELECTRICAL SAFETY ISSUES
Pay close attention to these important electrical and safety
issues.
■ CAL requires a grounded outlet. Always use a grounded
outlet and plug.
■ Do not use a ground-lifting adapter or cut the AC cable
ground pin.
■ Make sure the AC power cable for the loudspeaker has
the appropriate power plug (on the other end) for the
area in which you will operate the loudspeaker. In addition, the AC power cable must be rated for the total current draw of all loudspeakers looped from the power
source.
The minimum electrical service amperage required by a CAL
loudspeaker system is the sum of the Maximum Long-Term
Continuous Current for each loudspeaker. An additional
30 percent above the minimum amperage is recommended
to prevent peak voltage drops at the service entry.
NOTE: For best performance, the AC cable
voltage drop should not exceed 10 V, or
10 percent at 115 V and 5 percent at 230 V. Make
sure that even with AC voltage drops that the AC
voltage always remains within the operating windows.
■ Do not operate the unit if its power cable is frayed or bro-
ken.
■ Keep all liquids away from CAL loudspeakers to avoid
hazards from electrical shock.

The CAL user panel includes audio input connectors, both
analog and digital (AES/EBU), for receiving audio source signals; logic connectors for selecting presets, overriding and
muting audio output, and monitoring loudspeaker faults;
and network ports for interfacing to a Mac
®
or Windows®based computer running the Compass control software. The
network ports can also be used for receiving AVB audio
streams as audio source signals.
AUDIO INPUT
CAL includes four numbered audio inputs: three analog and
one digital. The three analog inputs also provide loop output
for looping multiple loudspeakers from a single audio
source. In the Compass control software, a single input is
specified as the active input, and another input can be specified as an override input (when the installation requires CAL
to function as part of a fire alarm or evacuation system).
NOTE: AVB audio streams received from the
Network / AVB ports can also be used as audio
sources. For more information, see “AVB Audio
Stream Input” on page 19.
NOTE: CAL ships from the factory with Analog
Input 1 selected as the active input, and no
input selected for the override input. These inputs
can be changed with the Compass control software.
For more information, refer to the Compass documentation included with CAL (also available at
www.meyersound.com
).
Analog Inputs (1–3)
CAL User Panel
Analog Audio Input and Loop Output Connectors
The three analog inputs use Phoenix 6-pin male connectors
and accept balanced audio signals with an input impedance
of 10 kOhm. The analog audio source is received via the
connector’s top three pins (shield, positive, and negative).
The signal is looped to the connector’s bottom three pins
(also shield, positive, and negative) for output when looping
multiple loudspeakers from a single audio source. The pins
for the analog connectors are clearly labeled on the CAL
user panel.

Status
The positive (+) and negative (–) pins carry the input as a differential signal. The shield (S) pin is connected to earth
through a 1 kOhm, 1000 pF, 15 V clamped network. This circuitry provides virtual ground lift for audio frequencies while
allowing unwanted signals to bleed to ground. When assembling cables, make sure all three pins are connected on both
ends. Telescopic grounding is not recommended, and shorting an input connector pin to the case may cause a ground
loop, resulting in hum.
Looping CAL Loudspeakers
The Analog input connectors allow multiple CAL loudspeakers to be looped from a single audio source. Connect the
loop output pins of the first loudspeaker to the input pins of
the second loudspeaker, and so forth. The loop output pins
are wired in parallel to the input pins and transmit the unbuffered source signal even when the loudspeaker is powered
off.
NOTE: Make sure that cabling for looped loud-
speakers is wired correctly (shield to shield,
positive to positive, and negative to negative) to prevent the polarity from being reversed. If one or more
loudspeakers in a system have reversed polarity, frequency response and coverage can be significantly
degraded.
Digital AES/EBU (4)
AES/EBU Input Connector
The digital input uses a Phoenix 6-pin male connector and
accepts an AES3 digital audio signal. The digital audio
source is received via the connector’s top three pins (shield,
positive, and negative). The connector’s bottom three pins
are not used. The pins for the digital connector are clearly
labeled on the CAL user panel.
Phoenix cable wired for looped audio
To avoid distortion when looping multiple CAL loudspeakers, make sure the source device can drive the total load
impedance of the looped loudspeakers. In addition, the
source device must be capable of delivering 20 dBV
(10 V rms into 600 ohms) to yield the maximum peak SPL
over the operating bandwidth of the loudspeaker.
To calculate the load impedance for the looped loudspeakers, divide 10 kOhms (the input impedance for a single CAL)
by the number of looped loudspeakers. For example, the
load impedance for 10 CAL loudspeakers is 1000 ohms
(10 kOhms / 10). To drive this number of looped loudspeakers, the source device should have an output impedance of
100 ohms or less.
NOTE: Most source devices are capable of
driving loads no smaller than 10 times their
output impedance.
NOTE: The AES/EBU port accepts single-
channel (mono) digital audio sources. When
connecting AES/EBU audio sources to CAL, you
must specify in the Compass control software
whether the left channel (AES L) or right channel
(AES R) will be used.
ON/STATUS LED
On/Status LED
During normal operation, CAL’s On/Status LED is green. If
the loudspeaker’s internal temperature reaches 75° C
(167° F), the LED turns solid yellow and the loudspeaker’s
gain is reduced by 3 dB. Though CAL will continue to operate normally with the lower gain, when the On/Status LED is
yellow, this is an indication that the loudspeaker is reaching
its maximum heat dissipation and a reduction in SPL is rec-

ommended. When the loudspeaker’s internal temperature
cools to 60° C (140° F), the amplifier returns to normal operation.
TIP: When CAL is connected to a computer
running the Compass control software, the RMS
tab provides additional feedback and warnings, if
encountered, on the loudspeaker’s operating temperature.
LIMIT LEDS
Limit LEDs
When source levels for CAL exceed the maximum input levels for its drivers, limiting is engaged and is indicated by the
two Limit LEDs on the CAL user panel. The left LED indicates limiting for low-frequency channels while the right LED
indicates limiting for high-frequency channels. When
engaged, limiting not only protects the drivers, but also prevents signal peaks from causing excessive distortion in the
amplifier channels, thereby preserving headroom and maintaining smooth frequency responses at high levels. When
source levels return to normal, below the limiter’s threshold,
limiting ceases.
CAL performs within its acoustical specifications when the
Limit LEDs are unlit, or if the LEDs are lit for 2 seconds or
less and then turn off for at least 1 second. If an LED
remains lit for longer than 3 seconds, the loudspeaker enters
hard limiting where:
■ Increases to the input level have no effect.
■ Distortion increases due to clipping and nonlinear driver
operation.
■ Drivers are subjected to excessive heat and excursion,
which will compromise their life span and may eventually
cause damage over time.
CAUTION: The Limit LEDs indicate when a
safe, optimum level is exceeded. If a CAL loudspeaker begins to limit before reaching the required
SPL, consider replacing it with a CAL model with
more amplifier channels, or consider adding more
CAL loudspeakers to the system to achieve the
desired SPL without exposing the loudspeakers to
excessive levels and possible overheating.
LOGIC I/O PORTS
The Logic I/O connectors provide a range of control and
monitoring for CAL, including changing presets, overriding
and muting the input signal, monitoring loudspeaker faults,
and providing voltage output. The Logic I/O connectors are
optically isolated from the CAL loudspeaker circuitry. The
three COM pins are isolated from each other to set the reference voltage for their associated logic pins. A logic pin is
triggered when it receives a voltage of 3 to 20 V DC greater
than its associated COM voltage.
CAUTION: Do not send voltages greater than
20 V DC to the Logic I/O pins as this may dam-
age the input circuitry.
Presets 1–4
Preset Pins
CAL presets recall loudspeaker settings for beam control
and processing (5-band parametric EQ, gain, and delay).
Presets are edited in the Compass control software. An
unlimited number of presets can be saved and stored on
your computer but only four presets can be stored in the
CAL loudspeaker. When CAL is not connected to a computer, presets can be selected by sending control voltages
to the A1 and A2 pins.
Table 1 illustrates the logic for selecting presets with control
voltages.
Table 1: CAL Preset Selection Logic
A1 A2
Preset 1 0 0
Preset 2 1 0
Preset 3 0 1
Preset 4 1 1
For example, to select preset 2, a voltage of 3 V DC is sent
to the A2 pin while 0 V DC is sent to the A1 and COM A2.
NOTE: The A1 and A2 pins are triggered when
receiving a voltage of 3 to 20 V DC greater than
their associated COM voltage.

CAL Factory Presets
A summary of the beam settings for the CAL factory presets
is shown in Table 2. CAL ships from the factory with these
presets loaded into the loudspeaker. The presets can be
edited and overwritten with the Compass control software.

Override and Mute Pins
For installations where CAL is part of a fire alarm or evacuation system, the loudspeaker’s active audio input (main program source) can be muted or replaced with an override
input (alarm or emergency announcement source). The mute
or override can be triggered with a relay closure attached to
the Mute or Override pins.
The Mute pin is triggered when it receives a voltage of 3 to
20 V DC greater than its associated COM pin. When triggered, the Mute pin instructs CAL to mute its audio output.
The Override pin is triggered when it receives a voltage of 3
to 20 V DC greater than its associated COM pin. When triggered, the Override pin instructs CAL to override the active
audio input with the override input. Both the active input and
override input are specified in the Compass control software.
Fault Contact Pins
The Fault Contact pins report when CAL shuts down or is no
longer active. When CAL is powered on and working normally, the NO (normally-open) pins are open and the NC
(normally-closed) pins are shorted together. When the loudspeaker is powered off, its internal relays switch so that the
NO (normally-open) pins are shorted and the NC (normallyclosed) pins are opened. The three Fault Contact pins are
provided to accommodate monitoring for either short circuits or open circuits.
18
+5 V DC Power Source
+5 V DC Pins
CAL offers a local +5 V DC power source as a convenient
means for controlling its Logic I/O features. The +5 V DC
pins provide an isolated +5 V DC output that can be connected to any of the Logic I/O pins through an external relay
or switch, eliminating the need for an external control voltage. The +5 V DC pin is fused at 0.35 A.

!
!
NETWORK / AVB PORTS
Network/AVB Connectors
CAL’s two Network / AVB ports use RJ-45 Ethernet connectors and allow the loudspeaker to be connected to a standard computer Ethernet port, network router, or network
switch with a CAT-5e cable. CAL’s Network / AVB ports are
AVB-enabled and use the IPv6 protocol for network communication. Two ports are provided for redundant control and
each has an independent Media Access Control (MAC)
address that is static and preassigned.
The yellow and green LEDs indicate connection and data
traffic as on standard Ethernet ports.
AMPLIFIER COOLING SYSTEM
CAL employs a combination of natural convection and
forced air in its cooling system. The amplifier’s heat sink provides natural convection cooling from the air flowing near its
fins. In addition, a single-speed fan circulates air internally to
ensure that CAL remains operational when exposed to high
ambient temperatures or when driven continuously at high
output levels.
CAUTION: The CAL heat sink can reach tem-
peratures up to 85° C (185° F) during extreme
operation. Use caution when approaching the rear of
the loudspeaker.
USER PANEL COVER
A user panel cover is included with CAL to protect the connectors from dust in indoor installations and the weather
elements in outdoor installations. The cover is installed by
default and must be removed to gain access to the user
panel.
When CAL is connected to a Mac or Windows-based computer, the Compass control software lets you configure
beam spread and beam angle and upload the settings as a
preset to CAL. Compass also includes an RMS tab for
remote monitoring of all CAL loudspeakers on the network.
AVB Audio Stream Input
AVB audio streams received from CAL’s Network / AVB
ports can be used as audio sources. In the Compass control
software, AVB audio streams for the connected port can be
specified as the active input or override input.
OLED BUTTON
The OLED button is located in the upper right of the CAL
user panel and provides visual feedback on the unit. During
startup, the OLED displays CAL’s Network port addresses.
The addresses can also be viewed after startup.
To view CAL’s Network port addresses:

CHAPTER 5: COMPASS CONTROL SOFTWARE
The Compass control software provides comprehensive
control of CAL through a graphical user interface. The software enables easy access to all CAL features and even provides control of multiple units. Compass runs on a Mac or
Window-based computer.
With Compass you can:
■ Set the active input and override input
■ Configure vertical beam spread, vertical beam angle, and
beam split
■ Assign processing to beams, including gain, delay, and
parametric EQ
■ Edit, store, recall, and organize CAL presets
■ Test logic I/O, including input mute, input override, fault
contact, and preset selection
■ Monitor loudspeaker system status and performance
data from the RMS tab
Compass includes full copy and paste of all settings and
groups of settings, and multiple levels of undo. The tabbed
interface can be scaled to any display resolution and the
colors can be configured for day or night. Compass has the
same user interface, whether running on a Mac or Windowsbased computer, so switching between platforms is completely transparent.
The RMS tab reports extensive system status and performance data for each CAL loudspeaker on the network,
including amplifier voltage, limiting activity, power output,
driver status, and temperature. The RMS Overview tab displays all CAL loudspeakers on the network with loudspeaker
icons with color-coded feedback for the different loudspeaker components.
Compass Control Software, RMS Overview Tab
TIP: For information on installing and using the
Compass control software, refer to the Compass documentation included with CAL (also available at www.meyersound.com

CHAPTER 6: MOUNTING CAL LOUDSPEAKERS
CAL comes standard with adjustable brackets that allow it
to be mounted on walls or columns.
NOTE: Before mounting CAL, make sure to
allow for the necessary cable runs to its audio
sources, host computer, and any control devices or
switches you intend to use.
IMPORTANT SAFETY CONSIDERATIONS!
When installing Meyer Sound loudspeakers, the following
precautions should always be observed:
■ All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reliability of any rigging or mounting method for their application. Rigging should only be carried out by
experienced professionals.
■ Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
■ Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.

CAL loudspeakers come preconfigured with its loudspeaker
brackets already installed. After installing the wall mount
plates, install CAL onto the wall, rotate the loudspeaker to
adjust its horizontal coverage, tighten the top and bottom
nuts, and attach the endcaps.
To mount CAL on a wall:
1. Mount the top and bottom wall mount plates on the wall:
■ Mark two holes on the wall for each wall mount plate
using their center mounting holes as a guide.
■ If you are mounting CAL on a wall with wood studs,
locate the wall stud.
■ Orient the wall mount plates with the side slots up and
make sure the top plate (the smaller one) is mounted the
appropriate distance above the lower plate for your CAL
loudspeaker.
■ Use a level and straight edge to make sure the top and
bottom wall mount plates are vertically aligned.
NOTE: Orient the wall mount plates with the
side slots up.
■ Drill pilot holes at the four marked locations. Make sure
not to over-drill the pilot holes. The depth and diameter
of the pilot holes should be around 50 percent of the
length and diameter of the fasteners.
NOTE: The center mounting holes for the wall
mount plates are 0.28 inches (7.1 mm) in diam-
eter.
■ If mounting CAL on a concrete or metal wall, install wall
anchors (not included) in the pilot holes. Install the wall
anchors so they are flush with the wall surface.
■ Secure the wall mount plates to the wall with fasteners
(not included) appropriate for the wall material and rated
to hold the weight of the loudspeaker.
