About Ashly
Ashly Audio was founded in 1974 by a group of recording engineers, concert sound professionals, and electronics designers.
The rst products were elaborate custom consoles for friends and associates, but business quickly spread to new clients and
the business grew. The philosophy we established from the very beginning holds true today: to offer only the highest quality
audio tools at an affordable cost to the professional user – ensuring reliability and long life. Many years later, Ashly remains
committed to these principles.
Unpacking
As a part of our system of quality control, every Ashly product is carefully inspected before leaving the factory to ensure awless appearance. After unpacking, please inspect for any physical damage. Save the shipping carton and all packing materials,
as they were carefully designed to reduce to a minimum the possibility of transportation damage should the unit again require
packing and shipping. In the event that damage has occurred, immediately notify your dealer so that a written claim to cover
the damages can be initiated.
The right to any claim against a public carrier can be forfeited if the carrier is not notied promptly and if the shipping carton
and packing materials are not available for inspection by the carrier. Save all packing materials until the claim has been settled.

2. PEMA AMPLIFIER MODELS
2.1 Product Overview
The Pema series of ampliers are available in the following 120VAC or 230VAC mains congurations. In addition to the standard
four Low Z models for regular speaker loads, Hi Z models are available in *25V, 70V, and 100V output versions. Also, each
model can have optional factory installed CobraNet or Dante network audio.
Pema 4125 - Eight input, four *125W amp channels
Pema 8125 - Eight input, eight *125W amp channels
Pema 4250 - Eight input, four 250W amp channels
Pema 8250 - Eight input, eight 250W amp channels
*The standard low Z 125W models also double as the 125W 25V constant voltage output version.
2.2 Installation Requirements
Each Pema model is 2RU, and weighs <26 pounds (11.8kg). The model number, mains voltage, and power consumption are
indicated on the back panel beneath the AC inlet.
Caution: Before mounting or wiring the unit, always disconnect it from the mains. Use four screws when mounting the ampli-
er to the front rack rails. Rear support is also recommended, especially for mobile or touring use. Air ow vents for cooling the
amplier require the front panel to have access to ambient room temperature air. Cool air is drawn in from the sides and blown
out the front. It is not necessary to leave a space above or below the amplier in the rack. To reduce the risk of re or electric
shock, do not expose this apparatus to rain or moisture. Before connecting to mains power, make sure that the controls, software,
and wiring are all set to the conguration needed for your particular application. Failure to do so could result in damage to the
unit or other components in the system.
Wiring: Always use high quality shielded cable for input signals, and use balanced input signal when possible. To avoid pos-
sible system noise or oscillation, avoid running low level signal wires parallel to speaker outputs or AC wiring, especially over
long distance. Before testing the system, double check all connections and settings. Refer to the specications section of this
manual for input, output, Ethernet, and other amplier properties to consider during installation.
2.3 Ethernet Communications Requirements
Ethernet communications with this amplier is made by connecting it directly to a PC running Proteane control software, or
connecting it to a networked PC through an Ethernet router, switch, hub, or patch panel. Networks using the Cat-5, Cat-5e, and
Cat-6 standard will all work with Pema ampliers. Maximum cable distance is 100 meters (328 ft) from the nearest router, hub,
or switch. Ashly network ampliers and remotes will auto detect their Ethernet connection, and adapt to either a straight through
pin to pin or crossover Ethernet cable.
2.3a IP Address - There is no need to assign IP addresses to Pema products used with a PC or a network router. The router or
Link Local Addressing will assign IP addresses to each product automatically.
When a router is not available, most current Pema and NE products have the capability to assign their own IP address based on
Link Local Addressing. This allows the device to operate without the need to set up static IP address. If the only option is to use
an Ethernet switch instead of a router, and communications problems remain which cannot be solved with the use of the link
local standard, each Pema device must have a static IP address assigned from within Proteane software. This is done by select-
ing “Manual Conguration” in the Network Properties tab of each device, where the system/network administrator must assign
each product its’ own unique static IP address, each with the appropriate sub net if applicable.

Operating Manual - Pema Protea Equipped Media Amplier
2.3b Firewalls - If Proteane software does not detect the amplier or show real time changes, the rewall in the host PC may
need to have Proteane software added to its rewall exceptions, since rewalls may block the amplier response to the PC. The
current PC rewall status is found by clicking on the Windows Start button, then Control Panel, then double clicking on the
security shield where rewall exceptions are congured.
2.3c Wi-Fi and LAN – For the initial device auto-conguration process, any secondary Wi-Fi connection should be disabled on
the PC, and the LAN (Local Area Network) connection must be enabled on the PC. Secondary network connections may confuse
the auto device discovery process. Go to the Windows Control Panel, then Network Connections, to disable any secondary network connections. Once communications with the device is established, secondary network connections can be enabled again.
2.3d Connecting Device(s) - Connect the Ethernet cable from the PC or network to the amplier. If a successful Ethernet
connection has been made, a solid green LED (Link) lights up on the amplier's RJ-45 Ethernet port. If there is no green LED
showing, there is either a problem with the cable or the network source which must be addressed before proceeding further. All
RJ-45 Ethernet ports ash green when active, so backtrack through any other cables, routers, or switches to nd the problem.
The ashing yellow LED (Data) indicates that data is owing to or from the amplier.
2.4 Front Panel Features
1. Mounting Holes – For rack mounting.
2. Power Switch – Switches the unit on or off. Note: The power switch can be disabled from Protea
3. Status LEDs – Indicate status of: Power, Standby, Protect, Power Switch Disable, and Com activity.
4. Cooling Vents – Cool air enters the sides and is vented out through the front.
5. Channel Controls – Channel control area.
6. Signal LEDs – The lowest LED will begin to light when the output voltage reaches -18dBu below rated output. The Clip
LEDs will begin to ash when output voltage is 1/2 volt below the output power supply voltage, or the front end is clipped.
7. Bridge – This LED indicates that the channel pair is selected to BRIDGE mode from within Protea
the odd input channel level control is active.
8. Temp and Current LEDs – The Temp LED indicates that the amplier channel has reached an excessively high operating
temperature and will gradually attenuate the signal to compensate. If unable to sufciently cool the channel, the amplier will
eventually go into protect mode. The Current LED conrms that the amplier output is delivered to a speaker load.
9. Channel Attenuators – These control the input signal level to the amp, and can be disabled from software.
10. Factory Reset – To reset all internal congurations (including presets and passwords) back to the original factory settings,
press and hold this recessed front panel momentary switch during power up until all channel LEDs sequence from bottom to
top. Upon reset completion, the LEDs will turn off and the amp will be in normal operating mode.

2.5 Rear Panel Features
1. Ethernet Port - This RJ-45 connector allows Ethernet control and monitoring of the amplier using Protea
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. When switched to TEL-
PBX, a 600 Ohm isolation transformer is inserted into the channel one input signal path. This transformer is designed for limited
bandwidth audio from a telephone paging system.
4. Balanced Mic/Line Input - This is used for a three wire (G, +, -) balanced analog input, and uses Euroblock connectors. If
an unbalanced input signal is to be connected here, wire the signal to (+), the input ground to (G), and connect (-) to (G).
5. Unbalanced Summed Mono Input - This pair of RCA jacks is used for analog line level (-10dBv) input, and sums a stereo
signal together for that input. Note: Unbalanced line level sources may reference their outputs to a different ground than the
Pema amplier, creating the potential for ground loop hum. Always use short cable lengths for unbalanced signals, routed away
from AC, video, or data cables, and make every effort to use a common grounding point for all devices. In the event there is
still ground loop hum, isolate the unbalanced input signal by using an in-line isolation transformer.
6. Digital I/O Slot – Installation of this option allows this amplier to be part of a CobraNet or Dante digital audio network.
7. Preamp Outputs - These Euroblock connectors provide access to post-DSP preamp signals for each channel, and are used
to drive other ampliers or processors with the same signal that is driving the power amplier. The preamp outputs are pseudobalanced, meaning they use single ended signal with balanced impedance, and can be wire balanced or unbalanced.
8. AUX Outputs - On four channel ampliers only, the four AUX outputs offer additional and independent post-DSP signals
for driving other ampliers or processors. AUX outputs are pseudo-balanced.
9. Euroblock Speaker Connectors - Used to connect to speakers or to distributed line transformers, depending on model.

software.
10. Remote Standby - These two contact closure pins are wired to a switch to remotely place the amp in standby.
11. Preset Recall - These four pins (using remote standby GND) can be wired to remote contact closure switches to recall one
of the rst four amplier stored presets. Preset recall function is dened within Protea
12. Data - These four pins offer serial data control and can be wired to Ashly remote control devices such as the WR-5 or RD8C. Ashly also offers an in-line converter called the INA-1 that allows the Data port to be used with RS-232 controllers.
13. Remote Level Control - These pins can be wired to remote 10k Ohm potentiometers such as the Ashly WR-1 for DC level
control of individual channels.
14. AC Inlet - Used for the detachable AC cord. Use only the Ashly Audio factory supplied AC cord.
15. Model Information - This sticker tells the model name, mains voltage, and mains power/current consumption.
WARNING: Do not remove or lift the mains connector ground.

2.6 Amplier Protection
Ashly Pema ampliers have the following protection circuits:
Over Current Protection - When the output current exceeds the amplier's safe operating limits. This occurs in the amplier
output stage.
Thermal Protection - The amplier senses output device temperature and adjusts a two-speed fan to keep the operating temperature within acceptable limits. If device temperatures exceed that limit, the input to that channel is rst reduced, and as a last
resort the power supply will be switched off while the fan continues to run.
Mains Protection – Protection within the power supply includes: In-rush Current Limitation during power up, Mains Over
Voltage Detection, and internal Mains Fuse Protection. To protect the Mains fuse against AC overcurrent due to excessive audio
output current, there is a protection scheme indicated on the amplier front panel and in Proteane software which reduces audio
output level until the overcurrent condition is no longer present.
DC Output Protection – If the amplier senses DC on an output it will shut down the power supply.
3. PROTEAne CONTROL SOFTWARE
3.1 Installing Software
Ashly Proteane software is included on a CD with each unit. Software updates may become available on the Ashly web site.
Autorun will launch the application <ProteaSystemSoftwareNE> to install the software.
Proteane Software Main Menu, Network Device Tree, and Project Canvas
Once the software has been installed on the computer and Ethernet connections with the amplier have been made, launch the
software. All available Ashly network enabled devices will be automatically detected and displayed in the Ashly Network device
tree on the left side of the main software startup window.
Device icons can be dragged onto the project canvas from the device tree, or placed as virtual devices in “Design Mode”. In
other words, a device icon on the canvas is not necessarily a live product. It may be a virtual device, or a device that is currently
off-line. In the device tree, all currently connected and active devices are highlighted in green. Ashly devices which have 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. The user can manually scan at any time as well with <Scan For Devices> at
the bottom of the network device tree. All devices broadcast their availability to the software when they start up.

Operating Manual - Pema Protea Equipped Media Amplier
In addition to detecting which models are currently online, any factory installed options within each amplier are detected. Dante
or CobraNet are the only options available for Pema. The software control surface for each device automatically displays available controls for installed options. Note: The user can nd and verify a single physical device on the network by right clicking
over the unit’s name in the drop down menu or picture on the canvas, and then click <Identify>, which will ash the Com LED
on that unit’s face panel for two seconds.
The project canvas is used to visually represent a sound system installation, and can display any of the networked Ashly processors, ampliers, and remotes used in that system. The user can also place an assortment of isolated control objects such as
level faders, single LEDs, meter bars, etc, and map them to specic device functions within that project. Once a control object
is placed using <Add Items>, right click on the control object to bring up its properties. Lines, rectangles, text, even image
les can be added to create a custom virtual control screen along with individual devices and control objects and be saved in
the project. To see all available canvas tools, right click anywhere over open canvas. Checking <Design Mode> allows placed
objects to be moved around, while unchecking <Design Mode> locks all objects in place.
Once Proteane software is installed and devices identied on the network, a new project can be created and saved. A project le
represents the physical hardware installation via canvas items plus all device settings. Individual properties are edited in the
control surface window (shown below) by double clicking on the specic Pema amplier.

3.2 Device Options
1) Flash Reprogram Mode - The amplier rmware can be updated by
downloading a new rmware le to the amplier over the network. Latest
rmware updates, if available, can be found on the Ashly website. When
the amplier is put into ash reprogram mode, the power and standby LEDs
both turn on and all audio function is suspended until ash reprogram is
completed. Note that Flash Reprogram only appears in the device options
menu when a live Pema device is connected.
2) Link Group Conguration - Link groups allow the controls for multiple
DSP functions to track each other across channels or even across devices.
For example - if two different channels or even different device graphic
equalizer blocks are linked, any change made to a control within either of
the equalizers will result in an identical change to the other. In other words,
DSP blocks may be linked within a single device, or across multiple devices
(assuming all devices share the network).
Each device will support up to 16 Link Groups. DSP function blocks may be assigned to these groups in software. Once assigned
to a group, all LIKE functions within DSP blocks assigned to a group will track DSP parameter changes. Note that more than
one type of DSP function block can be assigned to the same link group. Each link group may be assigned a name by the user,
and also be assigned a color for easy identication. For further details about linking, see the online help in Protea

software.
3) Power On Delay back on from software standby mode*. Delay is measured in mS, with the limit at 655,350 mS, or about 11 minutes. The power amplier
should always be the last device to power up, after other system components have turned on and stabilized. Note that the amplier must
rst be on for this change to take effect. *Power On Delay does not work when standby mode is activated by contact closure.
4) Sample Rate and Master Clock Source Selection - Changes to both of these settings can be made by clicking the <Show
Advanced Control> box in this menu item. Sample rate can be set to either 48kHz or 96kHz. Note that at 96kHz, the DSP usage
doubles, resulting in half the available processing power for lters, delay, limiting, etc. Also note that the Feedback Suppressor cannot be used at 96kHz sample rate. Factory default settings are Auto Selection for clock source and 48kHz sample rate.
5) DVCA Control - This feature is used in conjunction with the DSP
tab gain tool called <Gain w/VCA>. Use this feature to create up to
four gain subgroups as you would on a mixing console. Any input or
output channel can be added to one or more VCA subgroups for group
gain control. While no external hardware control is allowed for this
subgroup, a level fader control object can be added to the project canvas
and linked to this named VCA level control.
6) DSP Enable/Disable - This removes from operation the input, output, or matrix mixer DSP functions on any channel. When removed,
audio is passed directly through the stage that has been disabled.
Use this feature to delay the amplier turning on after power is provided, as well as after the amplier is turned
3.3 Preset Options
1) Preset Options - The Preset Options menu in the main device
window allows setups to be named, saved to, and recalled from the
amplier device as well as a computer on the network. Presets are a
snapshot of all current settings on a given device.
This device will store up to 31 internal presets, each storing control
data for all channels and audio functions. Preset names must be 20
characters or less. While working in Proteane software, changes to an
individual preset can be saved to the device using <Save Preset To
Protea>, or saved to the PC using <Save To Disk>. Individual preset
les use the extension (*.pne).
10
3.3 - Pema Preset Options
Page 11
Operating Manual - Pema Protea Equipped Media Amplier
2) Sub Presets: Instead of saving or recalling an entire preset affecting all device functions, a sub-preset affecting only a user
dened sub-set of DSP functions can be created. To create a sub-preset, rst check the box labeled <Selected for sub-presets>
in any and all DSP control blocks to be associated with this sub preset, then under the preset options menu click <Save Sub
Preset to Disk> or <Save Sub Preset to Protea>.
A preset or sub preset can be loaded to the Pema amplier by one of the following methods:
1) Use Proteane software on a PC connected to the network to recall les saved on either the PC or on the device.
2) Use contact closures to load presets 1-4 from memory by wiring switches to the rear panel contact closure connector.
3) Use an Ashly WR-5 or neWR-5 remote control.
4) Use the event scheduler
Note: A full preset recall event will overwrite any unsaved changes, so be sure the current conguration is saved before continuing or it will be lost. The device always loads the last working settings on power-up, so as to preserve any changes if the power
is accidentally turned off prior to saving a preset. Caution: A new preset may have dramatically different settings capable of
damaging sound system components, so be careful not to recall the wrong preset while the system is on.
3.4 Device Control Tabs
The following device control tabs are available for each Pema device. The tabs include Control Surface, Security, Network
Properties, DSP, Input Source, Meters, Meter Dynamics, Meters AutoLeveler, Metering, Event Scheduler, and Fault Log.
3.4 - Pema Device Control Tabs

Operating Manual - Pema Protea Equipped Media Amplier
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 amplier channel is switched into protect mode, meaning one or more fault
conditions are occurring. Fault conditions include overvoltage, overcurrent, and overtemperature.
Fuse Protect - This means that the amplier has automatically attenuated the signal in order to prevent an internal non-userserviceable fuse from blowing.
Rail Fault - This means that the output power supply has encountered a rail overvoltage fault.
Supply Fault - This means there is a general power supply fault. Fault conditions include fuse protect, overtemperature, and
overcurrent.
Stereo/Bridged selection - The drop-down selection box above each pair of adjacent channels
assigns stereo or bridge mode for that pair. In bridge mode, input signal is automatically taken
from the odd channel input and inverted, then sent to the even channel. The even channel
controls become disabled. Note that in bridge mode, the even channel software attenuators
will still reect the physical position of the amplier's front panel attenuators, even though
they are removed from control of bridged signal.
Channel Name - This user dened text box names the amplier output channel. Up to 20
characters can be used.
Clip/Mute LED - This LED shows when the amplier output is either muted or clipping.
Clipping is indicated when the output level is 1/2 Volt below the output power supply rails,
and accurately tracks AC line voltage sags. All outputs become muted when the unit is put
in standby mode. This LED always shows the same status as the amplier front panel clip/
mute LED.
Mute Button - This button mutes the output channel. Output mute can be controlled by the
event scheduler.
Polarity Button - This button inverts the polarity of the output channel signal.
Main Output Channel Fader - This controls the output attenuation. Output attenuation
below -40dB mutes the output.
Input Meter - This indicates the signal level in dBu as in arrives at the amplier section.
Output Meter - This indicates the amplier output level in dB below full rated output.
Protect LED - This individual channel protect LED indicates an overvoltage, overcurrent,
or overtemperature fault.
Current Meter - This shows that the amplier is delivering current to a load, and is useful
to determine if a speaker load is open or shorted.
Temperature Meter - This meter and temperature box show the current operating temperature
of the output devices. Excess of 100°C will trigger overtemperature protection.
Offset Link Group and Offset Faders - A group of output channels can be linked together to
attenuate the group as a whole without changing the relative levels of each channel. If a channel
is assigned to one of the 16 offset link groups, a colored triangular marker appears on the left side of the main fader graticule
for secondary level control of all channels in that group. Left click and drag this marker up or down to adjust the link group
level. The main level control faders can not be linked to a group. Note that more than 40dB of cumulative channel attenuation
causes the channel to mute.
3.4a - Pema Control Surface
Channel Functions
In addition to the control surface offset link group attenuator control (not the main fader), most DSP functions have a link group
check box in their work window to assign a specic DSP parameter to one of 16 link groups if desired. Link groups can be
renamed by clicking on any group name and entering the new name then pressing <enter> on the keyboard.

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. This is
the sum of the following attenuators: main fader, offset
link group attenuation, front panel and remote attenuators (if enabled).
Note: The maximum dynamic range of the amplier is
only achieved when the amplier’s attenuators are set to
the optimal value. The amplier’s cumulative attenuators (as listed in the above paragraph) are located in the
signal path after all DSP processing but before the power
amplier section. The optimal setting is determined by
the maximum input signal of +20 dBu (with the attenuators set far down), minus the input sensitivity of +6.2
dBu (with the attenuators set at 0 dB). This equates to
approximately 14 dB of attenuation. The amplier’s
specied dynamic range is measured with the attenuators
set to this optimal setting of 14 dB
3.4b Security Tab
Password protected user access is set up in the security tab. User names and password are stored within
the Pema amplier. User access is dened by the
primary user (admin or default). Available security
levels are: View only, DSP Output Channels Access,
DSP Input Channels Access, Preset Recall Access,
Audio Parameter Access, Audio Only Access, IP
only Access, and Full Access.
3.4c Network Properties Tab
In this tab, device information includes device type,
MAC address, and network connect status. Device
network conguration can be set to automatic DHCP

4. ASHLY REMOTE CONTROL DEVICES
In addition to Proteane software, the following remote control devices are available for select Pema functions. A complete list
of Pema remote control functions, descriptions, and compatible devices is found in section 5.
4.1 WR-1 - Remote DC Level Controller
The WR-1 is a dual potentiometer remote DC
level control that mounts in a standard US electrical wall box. It is wired to the “Remote Level
Control” Euroblock connector on the Pema back
panel. The WR-1 is a standalone remote level
control that requires no additional conguration
or software setup. Clear windows are provided
for user generated labels.
If using a potentiometer other than the WR-1,
use 10k Ohm and wire the Pema +5V pin to the
potentiometer's clockwise terminal, GND to the
counter-clockwise terminal, and channel pin (1-
8) to the wiper. Do not connect the WR-1 ground
connection to any other external grounds.
4.1 - WR-1 Assembly and Wiring
4.2 WR-1.5 - Remote DC Level Control,
Remote Preset Recall
The WR-1.5 has a potentiometer for remote DC level
control of one Pema channel, and a four position
rotary switch to recall Pema presets 1-4 as stored on
the amplier. Clear windows are provided for user
generated labels.
4.3 WR-2 Preset Recall Switches
The WR-2 offers selection of up to four amplier presets via
pushbutton switches. Each switch gets connected to a preset
recall pin on the back panel of the Pema amplier as shown in gure 4.3. Terminal numbers
P1-P4 correspond to the rst 4 presets stored in amplier memory. When a switch is closed, it's
preset is recalled. Windows are provided for a user-generated label.
4.2 - WR-1.5 Wiring
4.3 - WR-2 Wiring
4.4 WR-5 Programmable Button Controller
The WR-5 is a programmable button remote control which
mounts into a standard North America electrical wall box and
connects to a Pema amplier data port using four conductor
wire. Maximum cable length is 1000 ft using #24 gauge twisted
pair. A decora cover plate (not included) can be purchased at
hardware stores to cover the WR-5 electrical box and satisfy
the aesthetic needs of the installation. The WR-5 is phantom
powered from the amplier. Up to four different WR-5 remotes
can be wired in series and phantom powered from a Pema
amplier, and more can be added by using an Ashly RPS-18
remote power supply.
WR-5 buttons are programmed from Protea
number in its WR-5 device window. Each button has a status LED. Available functions include preset recall/scroll, mute, zone

4.5 RD-8C or RW-8C Programmable Fader Controller
The RD-8C (RW-8C) are fader controllers which are connected to the Pema amplier's
Data port and phantom powered from the amplier. 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. There are eight channels and
a master, each with a fader control and an on/off button. Note: Only one RD-8C can
be used per amplier, and use of an RD-8C will exclude the use of the data port for
a WR-5. One or the other remote control device may be connected, but not both.
4.6 INA-1 Inline RS-232 Adapter (not shown)
The Pema amplier Data Port uses a proprietary serial communications protocol
which can be converted to RS-232 using the Ashly INA-1 RS-232 adapter. This
allows the use of custom designed third party RS-232 controllers.
The neWR-5 is a network version of the WR-5,
using Ethernet to communicate with the amplier. The neWR-5 is powered using an IEEE
802.3af Class 1 Power over Ethernet (PoE)
switch or in-line PoE injector. If PoE is unavailable, use the Ashly RPS-18 (sold separately)
or an equivalent 15-48VDC power supply
capable of at least 2 watts per neWR-5. Wire
the DC supply to the neWR-5 external power
supply connector (see gure 4.7). neWR-5 current
draw is 38mA @48VDC, and 80mA@15VDC. A
decora cover plate (not included) can be purchased at hardware stores to satisfy the aesthetic needs of the installation.
4.7 - neWR-5 Networked Programmable Remote Control
4.5 - RD-8C or RW-8C-5 Wiring
The neWR-5 appears in the Proteane software device network tree and must be
assigned from its device window to a Pema amplier. The neWR-5 has six programmable function buttons which can light up green, red, or amber to display
status. Further information on LED status is found in the neWR-5 owner's manual.
To the right of the function buttons is a pocket in the mylar overlay for a printed
function label to be inserted. The two other buttons are used to adjust function
parameters such as gain or preset number, and are indicated by the LED display.
There is a hard-wired Lock-Out feature on the neWR-5, where the closing
of a switch wired to the lockout Euroblock renders all buttons inactive.
4.8 FR-8/FR-16 Programmable Fader Controller
4.8 - FR-8 and FR-16 Programmable Fader
The FR-8 and FR-16 are programmable fader controllers for networked Ashly
products with DSP. Using Protea
buttons can be programmed for individual or group channel level control, matrix
point level control, signal level display, mute, and A/B source selection. The FR
remotes can be wall mounted in an electrical box, panel mounted, or freestanding,
and have a back panel contact closure for a user lockout switch.
4.9 Ashly Remote App for iPad
A custom and secure touch-screen control surface for the iPad® can be created and

5. PEMA REMOTE CONTROL FUNCTIONS
This section lists all Pema functions that can be remotely controlled, and lists available devices or software for each function.
5.1 Power Switch Disable (Protea
ne
Software only)
When the power switch is turned off the amplier is completely off, UNLESS the power switch has been disabled from within
ne
Protea
software (Control Surface Tab), in which case the power switch on the amplier has no effect at all. If the power switch
has been disabled from software, the Pema amplier front panel DISABLE LED will be lit. Even if the AC power is removed,
the amplier’s internal memory will maintain the <power switch disabled> status until changed again from Protea
ne
software.
Performing a factory reset will clear and restore all internal amplier memory to factory settings.
Pema ampliers have three possible power states, OFF, ON, and STANDBY, each with a
status LED on the front panel. Control for these states is managed by the following:
5.2a - Remote Standby Contact Closure - When the two Euroblock pins labeled "Remote
Standby"on the back of the amplier are wired to a switch and connected, the amplier goes
into Standby mode, meaning the amplier is active but not fully powered up. For remote
standby to work, the power switch must be turned on OR be disabled through Protea
ne
soft-
ware. Open the switch to remove the amp from remote standby mode.
5.2b - Protea
ne
Software On/Standby - On/Standby in the Pema amplier software func-
tions the same as the hardware based remote standby contact closure on the back panel. The
software standby control does not override the Remote Standby contact closure control, they
both remain active at all times. See Control Surface Tab descriptions on page 11.
5.2c - Event Scheduler - Protea
ne
software offers an event scheduler for key Pema functions
Remote Standby
Contact Closure Wiring
including standby mode. With the event scheduler, the installer can assign one or more times of day or days of the week for the
amplier to automatically go into and come out of standby mode, disabling overall function and conserving power during those
times when the amplier is not being used. See the Event Scheduler Tab description on page 16.
5.2d - iPad - A Standby On/Off control button can be part of an iPad design, behaving the same as software standby.
A preset le is created when the user has made all required software settings, DSP processing settings, source selection, signal
routing, mixing, etc, for a given application using this device. A preset is essentially a snapshot of all current settings on a given
amplier. This Pema amplier can internally store up to 31 named presets, each preset storing control data for all channels and
audio functions. Individual preset les stored on a PC use the extension (*.pmc). While working in Protea
ne
software, changes
to an individual preset can be saved to the amplier using <Preset Options/Save Preset To Protea>, or saved to the PC using
<Preset Options/Save To Disk>. Sub Presets (collections of DSP parameters individually selected from software) are saved in
a similar fashion.
Presets can be recalled to the Pema amplier using the following methods:
5.3a - Protea
ne
Software - Use a direct or network Ethernet connection from the amplier to a PC using Protea
ne
software. Click
(Preset Options >Recall From Disk/Recall From Protea) to load a stored preset into the amplier.
5.3b - Contact Closure - The four contact closure connections on the amplier back panel allow for amplier presets #1-4
(presets already saved and stored in the amplier memory) to be loaded into the Pema amplier at the instant a remote switch
connected to one of pins 1-4 is connected to its ground pin.
5.3c - WR-5 - A WR-5 will appear in software as a captive device to its host amplier. The six buttons on the WR-5 can be
programmed to recall a specic amplier preset, or scroll through a dened list of presets.
5.3d - neWR-5 - A neWR-5 will appear in the software menu tree as a device on the network, and must be assigned to the Pema
amplier under control. Like the WR-5, the six buttons on the neWR-5 can be programmed to recall a specic amplier preset,
or scroll through a dened list of presets.
19

Operating Manual - Pema Protea Equipped Media Amplier
5.3e Event Scheduler - Protea
ne
software offers an event scheduler for several key Pema amplier functions including preset
recall. With the event scheduler, the installer can assign one or more times of day or days of the week for the Pema amplier to
automatically recall and load a new preset.
5.3f iPad - A Preset Recall function can be part of an iPad design.
Caution: A new preset may have dramatically different settings capable of damaging sound system components, so be careful
not to recall the wrong preset while the system is on.
5.4 Remote Gain Control (WR-1 DC Level Control, WR-1.5, WR-5, neWR-5, RD-8C, FR-8/16, Event Scheduler,
Proteane Software, iPad®)
5.4a - WR-1 DC Level Control - The WR-1 remote potentiometer functions as if it were a front panel attenuator but in a remote
location. Attenuation from a remote DC level control attenuator is cumulative with all other attenuation for a given channel,
including the front panel level control.
5.4b - WR-5 - WR-5 buttons can be individually programmed to select single or multiple input or output channels for remote
gain control. A gain range with a top and bottom limit can also be set for each gain button. Note: To use this feature, a (ne)WR-5 Remote Gain tool must be placed in one of the DSP processing blocks of the channels(s) to be controlled. Refer to section 3.4d,
item #2.
5.4c - neWR-5 - The neWR-5 uses an Ethernet network connection instead of the amplier's data port. Buttons are assigned
gain control function in the same manner as the WR-5.
5.4d - RD-8C - RD-8C faders are programmed from Protea
The RD-8C will appear in the software Ashly Network device tree as a captive device to the host Pema. Place a Remote Gain
function in the Pema DSP tab's input or output to assign fader control for that channel or group of channels. The RD-8C also
has a mute button for each fader which will mute all associated channels.
5.4e - FR-8/FR-16 - FR-8/16 faders are programmed from Protea
with Pema. The FR-8/16 is found in the software Ashly Network>Ashly Remotes device tree. Assign individual fader control
after selecting the targeted Pema amplier, then select Mixer, I/O Level, or A/B Source Select mode for each fader. Fader Scaling is available to set upper and lower limits.
5.4f - Event Scheduler - Protea
ne
software offers an event scheduler for several Pema amplier functions including changes to
WR-5 and neWR-5 remote control gain. With the event scheduler, the installer can assign one or more times of day or days of
the week for the Pema amplier to automatically change WR-5 and neWR-5 channel gain parameters.
ne

5.4g - Proteane Software - Real time gain control from software is available using a variety of tools. These include the main
amplier's software control surface using the channel main fader, a single fader gain control placed on an input or output channel, a digital VCA group gain control placed on an input or output, a WR-5 (or neWR-5) gain control, and the output channel
matrix mixer function.
5.4h - iPad - Gain controls can be part of an iPad design, including numeric readback labels that indicate current gain status.
5.5a - WR-5/RD-8C - WR-5 buttons can be programmed to mute and unmute single or multiple inputs or outputs.
The RD-8C has a mute button associated with each fader which mutes those channels associated with that fader.
5.5b - neWR-5 - The neWR-5 buttons can be programmed to mute and unmute single or multiple inputs or outputs.
5.5c - FR-8/FR-16 - FR-8/16 buttons by default will mute their corresponding fader channel(s). When a fader is set to A/B
Source Select mode however, the button toggles between two different sources and the mute function is disabled.
5.5d - Event Scheduler - The event scheduler can be set to automatically mute single or multiple inputs or outputs at a predetermined day and time, and likewise can unmute at a different time.

5.6 Remote Zone Source Selection (WR-5, neWR-5, Event Scheduler)
5.6a - WR-5 - WR-5 buttons can be programmed to select different input sources for one zone. A zone is typically one or more
amplier output channels driving speakers in a single listening area. In the WR-5 software control surface, select the output
channel(s) for the WR-5 zone by clicking <Select Zone Outputs>. This denes the WR-5 as controller for that zone, and its up/
down parameter buttons with LED display will adjust the overall zone level. Next, program individual buttons for selection of
input source(s) by setting button function to <Zone Source Selection> and assigning desired inputs.
If Exclusive Source Selection is checked, only the currently pressed button and associated inputs will be active, otherwise
multiple buttons will be active together and add or subtract input sources as dened.
To allow input source selection but not zone level changes, click the <Disable Zone Level Control>. The output level can still
be adjusted from software, but the WR-5 is locked out from making zone output level changes.
5.6b - neWR-5 - The neWR-5 offers the same zone source selection capabilities as the WR-5, with the addition of programmable limits on output gain level.
5.6c - Event Scheduler - Use the event scheduler <Output Source Select> feature to enable or disable a single input source on
a specic Pema amplier output or AUX output.

or Knowledge Base section.
Dante or CobraNet equipped Pema ampliers into a digital audio network. A summary of features for each
6.1 - Dante, created by Audinate, is an Ethernet based digital AV network technology that can use shared 100MB or 1GB
network infrastructure for delivery of high performance, high channel count audio signals.
Conguration of Dante audio streams requires the use of Dante Controller. This free software from Audinate is available for
either Windows or MAC®. Dante controller allows you to connect any Dante audio source channel (transmitter) to any Pema
input channel (receiver ) using a simple matrix.
Once the Dante Controller matrix is congured, use Proteane software to enable Pema input channels as Dante receivers. Go to
the amplier's input source tab in the software and select an input channel pair to <Network>. This connects the source audio
signals assigned in Dante Controller to the selected amplier inputs.
Dante Tx: Pema ampliers with installed Dante shipped mid 2017 will additionally function as Dante transmitters. This means
that the eight Pema input channels are made available to Dante Controller as individual digital audio sources for other Dante device
on the network. Pema audio signals sent out via Dante transmitter are taken after the input DSP section but before the routing
and matrix mixer section in the software. To know for sure if your Pema is Dante Tx compatible, refer to the Ashly website's
knowledge base which will have a document showing the lowest serial number for each Pema model compatible with Dante Tx.
Note that there is no Proteane software access to Dante Tx signals, they will simply become available to Dante Controller as sources.
6.2 - CobraNet
combination of software, hardware and network protocols which allows distribution of multiple channels of real-time, high quality
digital audio over a dedicated Ethernet network. Pema ampliers equipped with CobraNet can only receive network audio, they
can not transmit onto the CobraNet network.
In Proteane software, a CobraNet tab will appear if CobraNet is installed in the Pema amplier. The Input Source tab shows
the CobraNet audio routing and source controls as well as the status of individual receivers, bundles, and channels. For more
detailed information on CobraNet, visit the Ashly website knowledge base, search Proteane software on-line help, or visit the
