Overview: The AtlasIED AZMP8 is a 14 input / 8 output audio processor/amplifier that's part of the AtlasIED Atmosphere family of products. Each input channel features a full suite of DSP and dynamics options including Gates, De-Essers, Compressors, EQ, and Auto-Gain. Each of the output channels can be configured as 8 separate Zones and include 6-Band EQ, Automatic Noise Compensation, Limiter, along with speaker presets based on AtlasIED model speakers. Two groups of 4 output channels use AtlasIED's Power Sharing technology to provide up to 615W of power to each group (1200W total), with the power divided between the 4 output channels (up to 600W for a single channel). Other features include 4 rear-panel RJ-45 ports that let you add up to 16 (total) AtlasIED plug-and-play Wall-Plate Accessories (sold separately) including Input and Source/Volume controllers for each Zone. A built-in web-based user interface lets you easily configure the AZMP8 from a computer connected through an existing network. Built-in Wi-Fi provides easy access and control from a connected smartphone, tablet, or laptop. The AZMP8 can also be used with an existing Wi-Fi network.

Inputs: Six balanced inputs are provided on three 6-pin Euroblock (Phoenix) connectors, each accepting mic- or line-level signals. Four sets of stereo RCA jacks are provided for music playback from a CD, computer, or media device. Input signals on each pair of RCAs are summed to mono. Each Input can be assigned to any or all of the Output Zones.

Speaker Outputs:

• Euroblock: Four 4-pin Euroblock connectors provide the 8 powered output channels, with each accommodating speaker wire up to 14-gauge.
• SHS (RJ-45): Four RJ-45 ports, corresponding to the four speaker outputs, can provide up to 100W of output power for running AtlasIED SHS (Strategically Hidden Speakers) via a CAT5e connection. Each port is automatically current-limited to 1A to protect the attached CAT cable.

Power Sharing: The AZMP8 features AtlasIED's amplifier power sharing technology that can shift all the available power supply power to a single speaker channel or divide the power in any proportion to each of the 4 channels in each speaker group; channels 1-4 and 5-8. The total power available for each of the two output groups is 615W, which can be split in 5W increments between the four speaker channels. The maximum power available to a single channel is 600W. Power assignment for each output zone can be made through the on-board web interface. Typical setup examples include:

• Zone 1 = 150W
• Zone 2 = 50W
• Zone 3 = 10W
• Zone 4 = 250W
• Total Power = 460W
• Reserve Power = 155W

or

• Zone 1 = 5W
• Zone 2 = 5W
• Zone 3 = 5W
• Zone 4 = 600W
• Total Power = 615W
• Reserve Power = 0V

Hi-Z & Low-Z Operation: The AtlasIED AZMP8's flexible configuration lets you assign each speaker output zone (1-8) as either a Low-Z 4- or 8-ohm output, or as a Hi-Z 25V, 48V, 70V, or 100V output.

Line Outputs: Two outputs, on a single 6-pin Euroblock connector, provide balanced line-level signals for running to additional amplifiers or powered speakers.

GPIO (General Purpose Input/Output Ports): A 12-pin Euroblock connector contains the input and output connections for optional contact switches (sold separately).

• Common "C" (x3): Provides the common ground points for switches.
• Control Inputs "1-6" (x6): Can be configured in the User Interface for CC (Contact Closure), Normally Open, or 1.5-12VDC trigger. These can be used to Recall Scenes and triggering Message Playback.
• High Priority Input "F" (x1): This Input can be used to mute all zones, set all zones to a selected source, lock & alert any connected accessory controllers, play a message once or on a repeated basis.
•  Outputs (GPO-1 & GPO-2): Two individually assignable Voltage Trigger Outputs that can be configured for: Logic H, Logic L, Toggle, or Pulse - with Pulse Time adjustable in 50ms increments. These can be used to trigger functions such as changing Scenes or Message playback.

Signal Chain

Input Processing: Each Input Channel can have the following options applied, including any optional Wall-Plate Accessory input (A-XLR, A-RCA, A-BT). Settings for Wall-Plate Accessories will vary based on their type of input.

• Preamp Gain: Provides 0dB to +60dB of gain for either Mic- or Line-level sources.
• Phantom Power: Lets you apply +48V of phantom power to an input when using a condenser microphone.
• HPF: An 80Hz high-pass filter (-12dB/oct) can be used to roll-off the low-end frequencies of the incoming signal.
• Gate (Noise Gate): Reduces noise on an input when no signal is present. This is handy for keeping an open mic "quiet" when no one is speaking into it. Parameters include: Threshold, Attack Time, Hold Time, Release Time, and Range which lets you adjust the amount of gain reduction.
• De-Esser: Helps eliminate high-frequency sibilance ("S" sounds) in speech.
  • Frequency: Lets you set the frequency where the sibilance is more pronounced.
  • Sensitivity: Sets the level of the target frequency for the De-Esser to engage.
  • Amount: Sets the amount of gain reduction applied.
  • Hold Time: The amount of time the De-Esser is held after the signal level is reduced.
  • Release Time: Sets the amount of time for the De-Esser to fully disengage after the hold time has expired.
• Compressor: Automatically reduces peaks in volume for a smoother, less fluctuating signal level. Settings include: Threshold, Ratio, Knee, Attack Time, Hold Time, Release Time, and Makeup Gain.
• Parametric EQ: A 4-band parametric equalizer lets you assign each band to a frequency between 20Hz and 20kHz, along with setting the "Q" or width of each band. Other adjustments include the Gain for each band, High- and Low-Shelving, and a Notch Filter. Band 1 includes a High-Pass Filter, with 6-, 12-, and 24dB slopes available. Band 4 features a Low-Pass Filter with same available cutoff slopes.
• Auto-Gain: This setting tries to maintain a consistent output level regardless of the variations in the input signal level. This is helpful when multiple people will be using the same microphone, all having differing vocal levels. This feature is also helpful in leveling out inconsistent background music tracks.
  • Threshold: The signal level where the Auto-Gain feature will become active.
  • Target Level: This is the signal level the Auto-Gain will attempt to maintain.
  • Target Window: The output level where the Auto-Gain doesn't modify the signal, helping avoid the function being over-active.
  • Max Boost/Cut: Lets you dictate how much gain this feature will boost or cut to maintain the required output level.
  • Speed: Determines how fast the Auto-Gain feature makes its adjustments. A higher Speed setting is ideal for vocals, while a slower Speed is best for background music.
• Virtual Mix: Up to four Inputs can be combined into a sub-mix, letting you use a single fader to adjust the level of all simultaneously. Up to 4 Virtual Mixes can be saved.
• Signal Generator: A built-in signal generator lets you setup, test, and troubleshoot zones with a consistent audio source. Three signal types are available - Sine Wave, which lets you choose the frequency of the signal, White Noise, and Pink Noise.

Output Processing: Each of the 8 Zone Outputs provides additional processing and configuration.

• Name: Output Zones can be named for easy identification.
• Input Source: Determines which Input(s) will be routed to that Output.
• Output Level: A virtual fader lets you adjust the output level for that zone. The fader also acts as a signal meter, displaying Blue when a signal is present, and Red if the signal starts to clip.
• Mute: Each Output can be individually muted.
• Priority Ducker: Lets you select and fine-tune which input signal(s) will override or "duck" the selected output when active.
• Message Player: Audio files can be uploaded and saved in the AZMP8's message storage library where they can be selected by the system to play a message, tone, bell, or chime through any of the Output Zones. Messages can be saved to the AZMP8 as .WAV files (mono or stereo) up to 48kHz at any bit rate. Messages can be up to 15 minutes long.
• Speaker Presets: Provides pre-configured settings for a variety of Atlas speaker models, with the EQ tuned for that specific speaker type.
• Delay: The currently selected output signal can be delayed, if necessary, to sync with other speakers. Delay time can be from 0 to 500ms.
• Parametric EQ: A 6-band parametric equalizer lets you assign each band to a frequency between 20Hz and 20kHz, along with setting the "Q" or width of each band. Other adjustments include the Gain for each band, High- and Low-Shelving, and a Notch Filter. Band 1 includes a High-Pass Filter, with 6-, 12-, and 24dB slopes available. Band 6 features a Low-Pass Filter with same available cutoff slopes.
• Ambient Noise Compensation: This feature works in conjunction with the X-ANS Ambient Noise Sensor Accessory (sold separately). The system monitors the ambient noise level of a zone and can raise or lower the audio level accordingly. Ambient Noise Sensors only provide data back to the AZMP8, so it can't be "listened" to, avoiding any privacy concerns. ANC parameters include:
  • Slope: Determines how much gain will be applied to the output signal based on the change in noise level.
  • Attack: Amount of gain increase in dB or Seconds.
  • Release: Amount of gain decrease in dB or Seconds.
  • Sensitivity: Sets the level at which the ANC will start working.
• Limiter: The Output Limiter is used for taming transient peaks, keeping the output signal below a specified level. This can help prevent damage to speakers in the event of a sudden loud signal, like someone speaking too closely into a microphone or a mic is accidentally dropped. Adjustable parameters include: Threshold, Knee, Attack Time, Hold Time, and Release Time.

Additional Features

Scenes: Groups of settings can be named and saved as a Scene that can quickly and easily be recalled. Scenes can manually be selected from the configuration dashboard, or scheduled for automatic switching. GPO-1 & 2 (General Purpose Outputs) can be assigned to a Scene, allowing automatic trigger activation of an external function, such as activating a motorized screen in a certain zone. Scenes can be named for easy identification of which zone or area they pertain to.

QR Codes: The AZMP8 lets you assign specific parameters that can be controlled by any user in a zone, such as changing sources, volume, music playback, etc. Once configured, QR codes can be created, printed, and mounted to an optional placard in that zone, allowing users to simply scan the QR code with their device and operate the pre-defined functions, without having to download any apps.

Scheduler: Specific event actions can be scheduled to take place automatically in the Scheduler. Similar to a meeting calendar, an Event Time/Date/Start-Stop can be entered in the configuration dashboard, allowing zone configuration to switch automatically at the specified date and time. The Event log will show scheduled events that have taken place or are currently taking place, to confirm the operation.
