Indicator Definitions:

Channel Fault – Indicates the channel has shut down due to protection circuits. Check to make sure the output on

that channel is not shorted. If all channels indicate fault, the power supply has gone into protection. No audio will be passed until the fault is resolved. Channel Thermal – Indicates channel is at or close to over temp. When dim, the channel will start to lightly limit the output. When bright, the channel is heavily limiting the output. Channel Clip – A red light indicates the channel is at the onset of audible clip on the output. Excessive clipping can damage the speaker connected to the amplifier. If the LED is Amber, that indicates the channel is limiting. Signal Presence – This indicator illuminates when there is -40db of input signal present on that assigned output channel. Channel Ready – Indicates the channel is ready to pass audio. If this indicator is off, the channel may be in standby mode or the amplifier DSP is booting up.

1. You will notice there are no buttons on the front panel. This is intentional and prevents unwanted adjustments.

2. To power on the unit, on the back, you will notice an icon that looks like this: . Once you press this button, you will notice a LED below the button illuminate Blue. The amplifier has now turned on and has begun its boot sequence.

3. To turn the unit off, press the icon. You will notice the blue LED will change to green. The amplifier is now in a powered off state.

a. You can also simply remove AC power to the unit to power it down as well. The LED will turn

off completely. When you power the unit back on, it will return to the state it was in when you powered it off.

4. Factory default settings allow analog 1 to pass to channel 1 output, analog 2 to pass to channel 2 output and so on.

NETWORKING AND WEB UI | Control&Monitoring

There are 3 ways to communicate with the amplifier for control and monitoring:

1. A Built in Wi-Fi Access Point

2. Standard Ethernet 10/100 FAST Ethernet Connection via the RJ45 Connection.

3. You can connect the amplifier to the Venue’s Wi-Fi network.

1. Built-in Wi-Fi Access Point (WAP)

The built in Wi-Fi access point allows for a point-to-point connection. This means you will only be able to communicate to one Connect Series amplifier at a time.

Using WAP

1. Press Wi-Fi button on rear panel to activate Wi-Fi Access Point

2. Once enabled, the front LCD now displays an SSID and IP address

3. Connect your device (phone, tablet, computer) to the amplifier’s Wi-Fi network

4. Enter the IP address from the front panel LCD into your device’s web browser

5. Control and monitor via the built-in web browser-based UI

NOTE: If a Cat5 or Cat6 cable is plugged in, WAP mode is disabled. Remove the Cat cable when entering AP mode.

Dante connections can stay plugged in.

2. 10/100MB FAST Ethernet

In 10/100MB FAST Ethernet Mode, you will be able to see multiple amplifiers in the Web Browser Based UI.

Using 10/100MB FAST Ethernet

1. Connect via wired network using Cat5 or Cat6 cable

2. Once connected, the front LCD now displays an IP address

3. Connect your device (phone, tablet, computer) to the Local Area Network and enter the IP

address from the front panel LCD into your device’s web browser

4. Control and monitor via the built-in web browser-based UI

NOTE: Out of the box, the factory default settings require the amplifier to be connected to a DHCP switch.

3. Local Area Wi-Fi Network

Connecting multiple amplifiers to the venue’s Wi-Fi network allow you to see multiple amplifiers in the Web Browser Based UI.

Using Local Area Wi-Fi

1. Connect to the Web App UI (same as WAP instructions above) then navigate to networking menu

2. Check the “Wi-Fi Enabled” box

3. Type in existing Wi-Fi network’s SSID that you would like to connect to (case sensitive)

4. Enter password if necessary, to see amp’s IP address, subnet mask, and gateway info confirming

your status and click “Save”

5. Connect your device (phone, tablet, computer) to the existing Wi-Fi network you have selected for

the amp

6. Control and monitor via the built-in web browser-based UI

NOTE: only one connection method is available for remote connection. If Wi-Fi is enabled, the ethernet connection is shutdown.

Vice versa is also true.

GLOSSARY | FeaturesDefinitions

Analog Inputs: Balanced analog inputs with

34dB and 26dB selectable input sensitivity modes. In 34dB mode, the input sensitivity is

1.4 VRMS and allows you to achieve full output

in LowZ and 70V modes. In 26dB mode, the input sensitivity is 2.0 VRMS and allows you to achieve full output in 100V mode. These modes are selectable in the input mode of the WebUI.

Priority Input Router: The input router

allows you to send any input to any output. You can also send 1 input to multiple outputs or multiple inputs to multiple outputs. Simply select the input channel you would like to send to the output.

Mutes: The channel mutes are located after

the input signal. This allows you to see if you are still getting an input signal in the UI while still being able to mute the signal that is going to the output stage.

Lowz/HiZ Mode: The amplifier has a

selectable by channel LowZ/HiZ mode in the web browser-based UI. If you have a low impedance load, select the LowZ mode for that channel. If you are running a 70V load, select HiZ 70V. If you are running a 100V load, select HiZ 100V. Based on your selection, the amplifier will set the appropriate output voltage and current for the LowZ or HiZ selection.

HiZ Mode High Pass Filter: When you

select HiZ mode, you will notice a High Pass filter enabled by default at 80Hz. This is a user adjustable filter so you can move the filter up or down. This filter is to avoid 70V or 100V speaker transformer saturation by not allowing lower frequencies to pass through. This pass filter is separate from the high pass filter in the crossover section.

high

Smart Power Bridge: Smart Power Bridge

is a proprietary technology that allows you to gain the benefits of a bridged amplifier output without having to lose a channel like traditional amplifiers. If you have our Connect Series 704 amplifier with a power rating of 700 watts per channel, when you enable Smart Power Bridge, you can get 1400 watts of output on that channel and still have channels 2, 3, and 4 available. With traditional amplifiers in bridge mode, you use 2 channels. Smart Power Bridge gives you the benefits of a bridged output channel without sacrificing an output channel.

Channel Standby: Separate from auto-

standby, the channel standby feature allows you to disable the output of a channel manually.

Internal Signal Generator: The signal

generator allows the user to send an internal signal through to the output for testing and verification purposes. The user can select between Pink Noise, White Noise, or Sine Wave. When in Sine Wave mode, the user can select the desired frequency.

Low Pass Crossover Filters: The low

pass filter allows frequencies lower than the specified filter frequency to the output. There are 3 filter types available: Linkwitz-Riley, and Butterworth filters up to 48dB per Octave.

High Pass Crossover Filters: The low

pass filter allows frequencies higher than the specified filter frequency to the output. There are 3 filter types available: Linkwitz-Riley, and Butterworth filters up to 48dB per Octave.

GLOSSARY | FeaturesDefinitions CONTINUED

Bandpass Gain: This bandpass gain block

is located after the crossover points and allows the user to boost or reduce the gain by +/- 15dB

Output Polarity: This is a user adjustable

polarity setting after the crossover points allowing the user to invert the output signal.

Delay: 100milliseconds of delay is available in

the connect series amplifiers.

Parametric EQ Filters: 8 user adjustable

parametric filters are available per channel.

Speaker Limiter: The speaker limiter

allows the user to set output voltage limiting conditions in place to protect the speakers attached to the output. VRMS limiter settings prevent overheating while V Peak limiter setting prevent the speaker form over exerting.

Amplifier Protection Limiter: In the

event the amplifier needs to limit the output to protect itself, the amplifier protection limiter will automatically enable itself. The amplifier protection limiter can enable itself if the amplifier is running in the upper limits of its’ thermal capacity or if AC voltage drops below a threshold where it can deliver full power to the output. This is a factory setting meant to keep the amplifier operating safely.

Realtime Load Monitoring: This feature

allows the user to monitor the load impedance of any channel in Realtime. Once there is more than 5 VRMS on the output, the amplifier will automatically test the impedance of each channel and report it’s reading in the web browser-based UI.

Pilot Tone Monitoring: This is an

advanced feature that is intended to inaudible tone through the output so the user can monitor the impedance of the speakers connected to the output without having to send input signal.

send an

Saving and Loading Speaker Tuning Files: Saving speaker tuning files in the web

browser-based UI saves all the information in the crossover, parametric EQ, limiter, and load monitor section of the amplifier channel. Loading speaker tuning files loads all of the information into the crossover, parametric EQ, limiter and load monitor section of the amplifier channel.

Saving and Loading Amplifier Settings: Saving amplifier settings in the web

browser-based UI saves all of the information from the amplifier and it’s up to 4 channels of information. Loading amplifier settings in the web browser-based UI loads all of the information from the amplifier and it’s up to 4 channels of information.

Universal Switch Mode Power Supply with PFC

The power supply we’ve designed for our Connect Series amplifiers is a single stage interleaved PFC power supply. PFC and isolation stage (normally two separate power stages) merged into one stage with this type of supply. Consequently, this makes the design smaller, more efficient and cheaper for the power level.

the type of PFC we are using for LEA products is Active PFC. We chose Active PFC over Passive because, Active PFC has many advantages over Passive PFC, such as:

1st – Provides universal input and produces a regulated output voltage. 2nd – Active PFC is smaller and lighter, more so as power goes up. 3rd – It’s able to achieve unity power factor across a wide load and input range. 4th – Active PFC can reduce input current harmonics.

emPower Change is our commitment to environmental sustainability and a call to action for the world. We promise to emPower Change by minimizing our impact on the global environment. Every decision made while designing and constructing our Connect Series amplifier family has been scrutinized to ensure that we not only limit our own impact on the environment, but also provide our customers with the tools to limit their personal impact as well.

Our Browser-Based Web UI emPowers users to Know More about the performance of their amps and systems so that they can understand their impact and cut down on wasteful operations – ultimately optimizing their systems performance while eliminating wasted energy consumption. We have decided to Use Less materials by opting for digitally hosted user manuals opposed to printed and automated online services such as ordering, training, and support. And we strive to Be Thoughtful whenever we approach new opportunities and projects – such as our 100% recyclable Connect Series box design – so that we can make deliberate decisions that support our sustainability goals.

Connect Series Sustainability

By purchasing this amplifier, you are joining us to emPower Change through environmental sustainability. Go ahead and take a moment to feel good about yourself!

The amplifier itself is fully ROHS compliant and does not include any lead or other harmful chemicals known to harm the environment.

The Connect Series amplifier is extremely efficient when being used. During normal use, the amplifier averages over 90% efficiency meaning less than 10% of the AC power is being dissipated into heat. At idle, the amplifier draws very little power when compared to traditional amplifiers. If the amplifier is powered on but there is no signal sent to the amplifier, it will automatically go into Standby Mode reducing the AC power draw even further. Another unique feature is when the amplifier is connected to a PoE network, you can still control and monitor without AC mains being powered on. If you are controlling your amplifiers from an external source, you can remotely power on and off the amplifier via the external I/O connections. When remotely powered off in this manner, the amplifier greatly reduced the AC power draw resulting in very little power demand when the amplifier is not in use.

Connect Series Retirement Plan

Our products are designed to emPower Change for the long haul. But when it comes time to retire a longtime workhorse, we’ve made the process easy for you and easy on the environment. Here’s what you can do to properly retire your amplifier:
