Operating Manual - Pema Protea Equipped Media Amplifier 2. PEMA AMPLIFIER MODELS 2.1 Product Overview The Pema series of amplifiers are available in the following 120 VAC or 230 VAC mains configurations. Each model can have an optional factory installed CobraNet or Dante network audio module. Constant voltage amplifiers can include 25V, 70V, and 100V output models. Pema 4125 - Eight input, four 125W amp channels, low Z (speaker), or constant voltage (High Z) output models.
Operating Manual - Pema Protea Equipped Media Amplifier 2.3b Firewalls - If Proteane software does not detect the amplifier or show real time changes, the firewall in the host PC may need to have Proteane software added to its firewall exceptions, since firewalls may block the amplifier response to the PC. The current PC firewall status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the security shield where firewall exceptions are configured. 2.
Operating Manual - Pema Protea Equipped Media Amplifier 2.5 Rear Panel Features 1. Ethernet Port - This RJ-45 connector allows Ethernet control and monitoring of the amplifier using Proteane software. 2. Phantom Power Switch - This switch applies +15V phantom power to channel 1-4 balanced inputs. A separate switch is used for channels 5-8. 3. TEL-PBX Switch - This switches between Mic/Line and PBX analog input for channel one only.
Operating Manual - Pema Protea Equipped Media Amplifier 2.6 Amplifier Protection Ashly Pema amplifiers have the following protection circuits: Over Current Protection - When the output current exceeds the amplifier's safe operating limits. This occurs in the amplifier output stage. Thermal Protection - When the internal temperature is below 40°C the fan runs at its slowest speed. Above 40°C the speed is increased until it reaches its maximum value.
Operating Manual - Pema Protea Equipped Media Amplifier been previously installed but are currently off-line or unavailable are highlighted in red. Individual devices can be dragged onto the project canvas to simulate physical rack installation groups. Editing a device can be done from the device tree or an icon on the canvas. All changes made in software are executed in real time on the device. The software scans for active devices on start-up.
Operating Manual - Pema Protea Equipped Media Amplifier 3.2 Device Options 1) Flash Reprogram Mode - The amplifier firmware can be updated by downloading a new firmware file to the amplifier over the network. Latest firmware updates, if available, can be found on the Ashly website. When the amplifier is put into flash reprogram mode, the power and standby LEDs both turn on and all audio function is suspended until flash reprogram is completed.
Operating Manual - Pema Protea Equipped Media Amplifier 2) Sub Presets: Instead of saving or recalling an entire preset affecting all device functions, a sub-preset affecting only a user defined sub-set of DSP functions can be created. To create a sub-preset, first check the box labeled in any and all DSP control blocks to be associated with this sub preset, then under the preset options menu click or .
Operating Manual - Pema Protea Equipped Media Amplifier Channel Thermal - This software LED indicator becomes lit when the channel is operating at an excessive and unsustainable temperature. Channel Protect - This becomes lit when any amplifier channel is switched into protect mode, meaning one or more fault conditions are occurring. Fault conditions include overvoltage, overcurrent, and overtemperature.
Operating Manual - Pema Protea Equipped Media Amplifier Attenuators - These two dials indicate the physical position of hardware level controls on either the amp front panel or the remote DC level control (if present). Note that these will display the position of attenuators even when disabled in software. Total Attenuation - This indicates the total amount of attenuation being applied to the channel in dB.
Operating Manual - Pema Protea Equipped Media Amplifier 3.4d DSP Control Tab 3.4d - Pema DSP Control Tab The DSP tab includes an input side and an output side, with a cross linking matrix mixer in between. Key features of the DSP window include: Input Channel Number - Right click on this to bring up Clear, Copy/Paste, Link, and Sub Preset functions for that input channel. Input Channel Name - The user can name each input channel. Input Mute Button - Mutes the input.
Operating Manual - Pema Protea Equipped Media Amplifier 5) Delay - Speaker Delay at 48kHz sampling rate is ≤21mS, and Delay is ≤682mS.

Operating Manual - Pema Protea Equipped Media Amplifier 3.4e Input Source Tab Inputs are analog balanced mic/line, summed analog mono unbalanced RCA connectors, or digital audio input (optional). Analog mic/ line preamp gain of 0dB, +20dB, +40dB, or +60dB is selected in this window by clicking on the
icon. Setting the input source to Auto gives priority to digital audio inputs if they are installed. 3.4f Metering Tabs (not shown) 3.
Operating Manual - Pema Protea Equipped Media Amplifier 4. PEMA REMOTE CONTROL The following devices are currently available for remote control of Pema amplifier functions. Some devices control only one function, while others can control several different functions. Some remote control functions are also controlled by software.
Operating Manual - Pema Protea Equipped Media Amplifier 4.1e RD-8C or RW-8C Programmable Fader Controller - The RD-8C (RW-8C) are fader controllers which are connected to the Pema amplifier's Data port and phantom powered from the amplifier. Maximum cable length is 1000 ft using #24 gauge twisted pair. The RD-8C is a desktop controller, while the RW-8C is electronically the same but mounts as a wall plate using a standard North American 4-gang electrical box and connects using a Euroblock..
Operating Manual - Pema Protea Equipped Media Amplifier 4.2 Remote Control Functions: The following functions within the Pema amplifier can be remotely controlled.
