RECOMMENDED ACCESSORIES
Although not supplied with the OPA-10 ACTIVE System, On Point Audio recommends
using the OPA-10 Active system with a high-quality loudspeaker stand when used in
portable applications. On Point Audio also recommends the OPA-Sub Active when
additional low-frequency output and response is required. The OPA-Sub Active also
includes a 35 mm / 1.375 inch diameter mounting pole that allows the OPA10 Active to
be safely elevated above the OPA-Sub Active.

The OPA Sub Active pole is NON-adjustable. DO NOT substitute poles. Make sure that
the OPA Sub Active is placed on a level surface.
OTHER ACCESSORIES
On Point Audio offers an external U-Bracket for use with OPA-10 Active enclosures.
This U-Bracket is the OPA-10-U.
On Point Audio also offers the Eye Bolt Kit that contains 4 x 304-grade stainless steel,
forged-shoulder eyebolts for suspending the OPA-10 Active.
FEATURES AND APPLICATIONS
The OPA-10 Active is a professional product and is designed to be used with a high-
quality mixing console. The OPA-10 Active does not provide any additional, user-
selectable, equalization or gain. Equalization and gain functions should be provided by
the mixing console. This design enables gain stages to be limited, thus reducing system
noise as well as substantially reducing the possibility of gain stage overloads.

On Point Audio does not feel that adding additional EQ and gain functions are
necessary or appropriate for truly professional products. The addition of redundant
functions such as EQ and gain are usually the cause of clipping, distortion and greatly-
reduced system performance and output. Any venue-specific equalization needs are
best provided by high-quality outboard devices or high-performance EQ sections found
on professional quality mixing consoles.
The OPA-10 Active features an onboard digital signal processor (DSP) that performs
analog to digital conversion, equalization, high-order crossover, delay and system
dynamics processing. The system’s dynamics processing consists of a
compressor/limiter function designed to provide ultra-fast threshold system protection
and maximized system dynamics.
SETUP AND USE OF THE OPA-10 ACTIVE
AC MAINS CONNECTION
Prior to connecting the AC mains cable, please insure that the AC mains switch on the
OPA-10 Active is in the OFF position.
On/Off Switch
The OPA-10 Active will operate on AC mains voltages of 115 volts to 230 volts. (The
OPA-10 Active uses an internal “autoswitch” circuit) The required AC mains frequency
is between 50 Hz and 60 Hz. The operating voltage is between 104VAC and 253VAC
The OPA-10 Active uses a standard IEC-type AC mains connector system. To mate the
AC mains cable with the AC mains connector on the amplifier, simply align the plug with
the panel’s connector and press the AC mains cable into place. Always support the
OPA 10 Active’s enclosure with one hand while performing this operation. The AC

mains connector is shown below. It is located on the lower portion of the OPA-10
Active’s input panel.
NOTE: The OPA-10 Active is supplied with two AC Mains cables. Select the cable with
the proper termination for the country specific mating receptacle!
AC Mains panel connector
To disconnect the cable end from the AC mains connector, pull back on the molded
plug at the end of the cable, not on the cable itself.
NOTE: ALWAYS turn off the AC mains power BEFORE attempting to disconnect the
AC mains cable from the OPA 10 Active amplifier module!
DO NOT CONNECT THE AC MAINS END OF THE AC MAINS CABLE IN AN AREA
THAT IS WET OR SUBJECT TO CONDENSATION OR DAMP CONDITIONS!
Once the AC mains cable is securely connected to both the amplifier and AC mains
supply, the OPA-10 Active enclosure may be turned on. It is good practice is to make
sure the audio levels on the mixer output (or other source output) are reduced or muted
prior to applying power to the OPA-10 Active.
NOTE: When power is applied to the OPA-10 Active and the unit is turned on, there is
approximately a 5 to 15 second delay before the pilot light illuminates.

Pilot Light
NOTE: If the pilot light does not illuminate within 30 seconds, the unit may be in a
FAULT CONDITION. If this occurs, the system should be returned to On Point Audio for
evaluation.
THERE ARE NO USER-SERVICABLE PARTS INSIDE. DO NOT REMOVE THE
AMPLIFIER MODULE!
AUDIO CONNECTIONS
The OPA-10 Active includes both male and female XLR-type connectors. Any standard
XLR-type cable end connectors may be used.
The image below illustrates the top portion of the OPA 10 Active input plate. Both the
audio input and audio thru connectors are shown.

Input Thru
An audio input level of 1.5 V RMS will drive the OPA 10 Active amplifier to full power.
The OPA-10 Active’s input section also allows for “paralleling” multiple OPA-10 Active
or other powered systems. This function is achieved by using the output/thru XLR-type
connector located next to the input XLR-type connector on the OPA-10 Active’s
amplifier module.
RIGGING AND SUSPENSION OF THE OPA-10 Active
The OPA-10 Active features 10 x M10 (metric) stainless steel rigging points. These
rigging points enable the system to be suspended for temporary or permanent
installations. There are three M10 points on the top of the enclosure, three on the
bottom of the enclosure and two on each side.
The M10 rigging points are shown in the image below.
Rigging Points shown above

The OPA-10 Active may also be mounted to any high-quality loudspeaker stand with a
standard 1.375 inch (35 mm) diameter mounting pole. The mounting pole MUST be
located on a level surface that is capable of safely supporting the weight of both the
loudspeaker stand and the OPA-10 Active.
DO NOT ADD OR SUSPEND ANY OTHER ITEMS FROM THE OPA-10 Active OR ITS
LOUDSPEAKER STAND

ALL ASSOCIATED RIGGING IS THE RESPONSIBILITY OF OTHERS.
ROTATING THE HF HORN
The OPA-10 Active’s HF horn has a coverage pattern of 90o Horizontal X 40o Vertical
which is preferred when the speaker is positioned vertically. The horn/driver assembly
can be rotated to deliver 40o X 90o when the speaker is positioned horizontally or for
other applications.
To rotate the horn assembly, first remove all the screws on each side of the grille and
remove the grille from the system. Then remove the screws around the perimeter of the
horn. After doing this, the horn can be easily rotated in either direction thanks to its
square shape. It is not necessary to disconnect the connections to the compression
driver when rotating the horn.

USING THE OPA-10 Active (Application and Trouble Shooting Tips)
The OPA 10 Active is a high-quality professional sound reinforcement system designed
for use in indoor applications. Some basic precautions will insure its long-term reliability.
EQUALIZATION AND GAIN
The OPA-10 Active has all the required equalization and gain functions included in its
internal Digital Signal Processor (DSP). Both the equalization and gain functions have
been optimized for flat frequency response and maximized system dynamics. The OPA-
10 Active does not have user-settable external gain or EQ.
All system gain should be set via the outboard mixing console. The mixing console
should be capable of providing sufficient output levels to supply the necessary voltage
levels to drive the OPA-10 Active to full power and still insure adequate headroom in the
mixing console.
The OPA-10 Active will produce full power with a 1.5 V RMS input signal.
If additional equalization is required, care should be taken to avoid excessive EQ in any
frequency band, but particularly at low frequencies. Excessive equalization can produce
“band selective” clipping and distortion. All EQ boost levels should be monitored if
system distortion is present.
Applications that require excessive low-frequency equalization are almost always an
indication that a subwoofer is required. On Point Audio also offers the OPA-Sub Active.
The OPA-Sub Active is a companion product designed for use with the OPA-10 Active
and it will provide substantial low-frequency acoustic output.
DISTORTED SOUND
When input levels to the OPA-10 Active exceed 1.5 V RMS, the internal dynamics
processing functions will engage and provide protection for the system. However, it is
still possible to “overdrive” the input section of the system. If distorted sound is present
the following steps should be taken:
1. Verify that the mixer’s output is not clipping or overloaded. If the output metering
of the mixing console is continuously in the “red” then the output level should be
reduced. (occasional “red” indications are usually fine and are dependent on the
mixing console’s output capability).
2. Verify that excessive equalization is not present anywhere in the signal chain.
3. Verify that AC mains levels are within the required range.

Voltage measurements on the AC Mains should be performed by a licensed electrician
or individual trained in making high-voltage measurements.
NO SOUND
1. Verify that signal is present on the input of the OPA-10 Active.
The OPA-10 Active also includes a “signal present” indicator and is positioned
immediately below the Pilot light. This indicator will illuminate when an audio
signal is present at the input to the system.
The threshold is approximately -25dBV.
2. Verify that there is AC Mains voltage on the AC Mains input to the OPA-10 Active
3. If AC Mains voltage is present, verify that the OPA 10 Active’s fuse is not blown.
NOTE: IF THE FUSE IS BLOWN, REPLACE ONLY WITH THE SAME TYPE OF FUSE.
THIS FUSE TYPE IS NOTED ON THE INPUT PANEL NEAR THE FUSE HOLDER.
THE LOCATION OF THE FUSE HOLDER IS SHOWN BELOW. NOTE: 115Vrms AC
fuse shown below for example only. Fuse rating will differ based on AC mains voltage.
