Note: For half-rack FX models, the rack and desk/wall mounting components described and illustrated in Sections 3.1 and 3.2 are not included with amplifiers, but are available to purchase as accessories. Contact your amplifier re-seller for more information.

3.1 FX Mounting

FX 2U full-rack amps include rack-mount ears.

FX half-rack amplifiers are shipped without any rack-mount hardware. A rack-mount kit can be purchased separately and configured as illustrated in Diagram 3a.

The installation and equipment rack should be configured to provide appropriate ventilation airflow space around the sides and rear of the amplifier as illustrated in Diagrams 1a - 1c. Ventilation airflow space of at least 25 mm (1 in) should be maintained along at least one side of the amplifier at all times. Ventilation apertures are also located on the rear panel of the amplifier and must not be obstructed. It is important to retain at least 80 mm (3.1 in) free space for airflow behind the amplifier rear panel.

Installation

3.2 Free-standing

If not installed in an equipment rack, FX amplifiers can be placed free-standing on a flat surface. Adhesive rubber feet are supplied with all FX models for this purpose.

FX half-rack amplifiers can be attached to the underside of desks or wall mounted using connecting plate hardware. The adhesive rubber feet should also be used in these circumstances to minimize the possibility of vibration between the amplifier and mounting surface. Wall and desk mounting is illustrated in Diagrams 3d and 3e.

It is important in any free standing installation that airflow through the amplifier’s side panel mounted fans and rear panel ventilation apertures is not compromised by adjacent items. At least 80mm of free space behind the amplifier and 25mm along at least one side (for half-rack units)should be retained at all times.

Note: Full-rack models do not have kits for mounting to a wall or underneath a table, they can only be used free-standing or rackmounted.

Configuration

4. Configuration

Before making input, output and GPIO connections, an initial FX amplifier configuration should be established. It is particularly important that the output amplifier format is configured appropriately for the speakers that are to be connected.

Configuration requires that FX amplifiers are connected to mains power and network services. These connections are described in the following two sections.

4.1 Mains Power Connection

FX amplifiers incorporate a power factor corrected power supply and can be used with mains input voltage from 100VAC to 240VAC, 50/60Hz. Use the mains cable supplied with the amplifier and connect it to a switched mains supply.

FX half-rack amplifiers have no mains power switch and are operational as soon as mains power is connected. Full-rack models have a front panel power switch.

4.2 Network Services

FX amplifiers are configured via a web page interface launched from the amplifier using a TCP/IP Ethernet network connection.

In order to access the web page interface, FX amplifiers must first connect to the browser device, or to the network used by the browser device.

That connection can be made using a wired LAN (use CAT5, CAT5E, or CAT6 cable), the FX amplifier's built-in WiFi Access Point (hotspot), or a local WiFi network (Client Mode).

• Wired LAN (local area network)

A wired LAN connection can be made using Ethernet cable connected directly to a PC, or to a PC through an Ethernet switch/router using CAT5, CAT5E, or CAT6 cable. Note: the FX

amp, PC, and router (if used) must all be on the same subnet.

Static IP connection: LAN connection uses a Static IP address, meaning the browser must connect using a predetermined fixed IP address. The default IP address for a wired LAN connection on FX amplifiers is

192.168.64.100. A different Static IP address may be assigned in the FX LAN configuration page.

Ashly recommends using a Static IP address for permanent installations. Note: If your network

devices are connected through a router, then you must log in to the router and set a Static IP reservation for the FX amplifier.

DHCP connection: The FX amplifier can also be configured in the Settings>LAN menu to instead connect using DHCP, meaning the amplifier receives an IP address automatically assigned by the router. It is not recommended to use DHCP for permanent installations, since the router could potentially change the IP assignment to the FX at any time.

The front panel Network indicator LED will illuminate green to indicate the amplifier has been successfully connected to a wired LAN. To view the current wired LAN IP address on a properly connected unit, go to the FX configuration Dashboard page.

If for some reason you are unable to open the configuration interface using the wired LAN connection, use the WiFi Access Point interface instead, described in the next section. Once connected using WiFi, wired LAN settings can be reviewed and configured.

Out of the box, the FX Wired

• WiFi Access Point (hotspot)

Every FX amplifier offers its own dedicated WiFi access point, or "hotspot", for a direct wireless connection to a browser device with no outside network required.

1. With the FX amplifier connected to mains power, wait for the front panel WiFi indicator to illuminate green. This indicates the FX amplifier's Access Point WiFi is available.

2. Using a laptop, tablet, or mobile device, search for available WiFi networks. Connect to the WiFi network called "Ashly FX (+ model name + serial number)". The serial number is found on the rear panel. Enter the password, "password", which can be renamed later, then connect.

Once the WiFi Access Point connection

is made, open a web browser and enter the IP address 192.168.4.1. The amplifier configuration web page interface will open.

Click on the Settings>Wifi menu for further WiFi options including enable/disable WiFi, enable/ disable WiFi when connected to LAN, disable WiFi after 5/10/30 minutes, and reset.

• WiFi Client Mode

To connect and configure the FX amplifier using a local WiFi network instead of its dedicated Access Point WiFi, *set the WiFi mode to "Client" in the Settings>WiFi menu. Enter the local WiFi network name (SSID) and password, then click *apply.

*Note: Before changing to WiFi Client Mode, be sure to first establish a successful wired LAN connection. Setting WiFi to Client mode disables access to the FX amplifier's Access Point WiFi. Having a wired LAN connection assures access to the amplifier in case something goes wrong with the local area WiFi connection.

The GPIO Volume Control enables an external potentiometer assembly such as the Ashly WR-1 to remotely control level of the assigned zone. The complete GPIO configuration menu can be found in the Settings>GPIO menu. (see

sec. 7)

Zone - Compressor

The Compressor option allows for default or custom (manual) signal compression settings to be applied to the selected zone.

Page 11

FX Amplifier • Operating Manual

Configuration

Note: Compression can be useful to reduce the volume difference between loud and quiet audio material. The lower the compression threshold is set, the more the difference between loud and soft will be reduced. The overall zone volume may need to be increased when compression is used. The default compression parameters are appropriate for most installations.

5.4 Output (Speaker) Tab

The Output Tab configures the selected amplifier speaker output, with additional submenus listed below.

For all Output menus, the amplifier output (speaker channel) under configuration is selected by highlighting one of the output identifiers (1, 2, 3 or 4) at the top of the page.

Note: The number of individual outputs available for configuration will depend on the FX amplifier model and the input, zone and output mode configuration.

• Routing menu

assigns the zone source used for the selected output.

• Delay menu provides time delay up to

100ms to be applied to the selected output.

• Equalizer menu enables 10-band

parametric equalization to be applied to the selected output. Equalizer settings configured for one output can be copied and applied to another output channel.

5.4a Output Presets

Within the Output tab, a Speaker Preset sub-menu allows custom configuration of parameters which can then be exported as a *.zcp speaker preset file. The *.zcp file is exported to the same download location used by your browser.

Created speaker preset files can then be added to a Speaker Library (see

sec. 5.5) for repeated

use later.

The following parameters can be individually edited, saved, and locked within a speaker preset file:

• Crossover & Gain

menu enables high or low-pass crossover filters and gain adjustment to be applied to individual amplifier outputs. Crossover filter settings configured for one amplifier output can be copied and applied to other outputs. Note: See the specifications section for a list of all available filter types and slopes.

• Speaker EQ menu enables several types

of equalization to be applied to individual amplifier outputs following the application of crossover filtering. Equalizer settings configured for one amplifier output can be copied and applied to other outputs. Note: See the specifications section for a list of all available filter types.

• FIR menu enables importing of FIR filters up

to 512 taps (coefficients).

• Driver Alignment menu enables time

delay up to 10ms to be applied to individual amplifier outputs following the application of crossover filtering.

• Polarity menu enables the polarity of

individual amplifier outputs to be reversed.

• Limiter menu enables Clip, Peak, and

RMS signal limiting to be to be applied to individual amplifier outputs.

• Output Mode menu enables individual

amplifier outputs to be switched off or configured for Low-Z or Hi-Z modes.

In either Hi-Z mode, 70V or 100V, a high-pass filter can be enabled from 20Hz to 200Hz.

Note: Use of a high-pass filter with Hi-Z mode loudspeakers is useful to avoid the possibility of distortion caused by low frequency line transformer saturation. Begin with the default filter setting of 70Hz. If low frequency distortion is still audible, increase the frequency setting one step at a time until the distortion is no longer audible.

6. Setup and Signal Routing

Thanks to their network based configuration features, FX amplifiers offer considerable versatility in terms of sources, signal routing, installation zones and output modes. Inputs can be freely assigned to installation zones, and those zones assigned freely to the available amplifier outputs in either Low-Z or Hi-Z modes.

This versatility enables, for example, one amplifier simultaneously to drive both Low-Z and Hi-Z speakers, or for different inputs to be routed to different output zones.

The following paragraphs describe and illustrate the recommended procedure for configuring zone and output routing. A general signal flow schematic is illustrated in section 10.

6.1 Input Setup

1) Open the configuration Dashboard and select the Input Tab.

2) Select the Input Name field and enter text.

3) Define the input as mono or stereo by selecting the appropriate option. Defining a stereo input will reduce the total number of discrete inputs available.

4) Select an input sensitivity option from the drop-down menu: +14dB, +4dB, -10dB and ‘microphone’ options are available. Generally, the +14dB or +4dB options are appropriate for ‘professional audio’ source hardware with balanced outputs, while the -10dB option is more appropriate for ‘consumer audio’ source hardware with unbalanced outputs. The ‘microphone’ option provides the significantly greater sensitivity required for microphones.

Note: Only dynamic microphones are suitable for connection. Phantom power for condenser microphones is not provided.

5) If necessary, adjust the input gain using the slider or up/down icons. Gain adjustment is intended to be used for fine output level adjustment following initial use.

6.2 Zone Setup & Routing

1) Open the configuration Dashboard and select the Zone Tab.

2) Select the zone to be configured. The number of zones available will depend on the amplifier model, input setup (mono or stereo) and output mode (Low-Z or Hi-Z). For example, a two output amplifier will have two zones available if only mono inputs configured, but have only one zone available if any stereo input is configured. Similarly, a four output amplifier with only mono inputs configured but one output configured for Hi-Z mode will have only three zones available.

Note: When configured in Hi-Z mode, FX amplifiers operate in ‘bridged’ mode where the output of two channels is combined. This means that the number of output channels available in Hi-Z mode is half that available in Lo-Z mode.

3) Name the zone by entering text in the Zone Name field.

4) Adjust the zone volume if required by using the slider.

5) Define a mono or stereo zone by selecting the appropriate option. Defining a stereo zone will reduce the total number of further zones available.

6) Specify an input source for the zone by selecting from the drop down source menu. Note: Selecting a stereo input for a mono zone will automatically sum the stereo channels to mono.

7) Set up GPIO Volume Control for each zone if desired. (see section 7 for details)

8) Set up Compressor for each zone if desired.

6.3 Output Setup

1) Open the configuration Dashboard and select the Output Tab.

Select the output to be configured. The number of outputs available will depend on the amplifier model, zone setup and output mode. For example, a two output amplifier will have two outputs available if Low-Z mode is selected but only one output available if Hi-Z mode is selected.

3) Name the output by typing in the Output Name field.

Note: Specifying a Zone as stereo will automatically generate three output channel source options: left channel, right channel or summed mono. On a four channel amplifier, the summed mono signal can potentially be used to drive a subwoofer, while two other channels are used for L/R.

4) Select the mode required for the output. The number of outputs available will depend on the amplifier model, input setup and zone setup. For example, a two output amplifier will have two outputs available if Low-Z mode is selected but only one output available if Hi-Z mode is selected.

8. Connections

8.1 Mains Power Connection

FX amplifiers incorporate a power factor corrected universal power supply and can be used with mains input voltage from 100VAC to 240VAC, 50/60Hz. Use the mains cable supplied with the amplifier.

FX half-rack amplifiers have no mains power switch and are operational as soon as mains power is connected. Ensure that all signal, GPIO and output connections are made before connecting the amplifier to mains power.

8.2 Input Connections

All FX amplifier models provide four balanced or unbalanced analog audio inputs and a stereo S/PDIF digital audio input. Any input channel can be routed to any zone using the Zone>Source menu. See Sections 6.2 or 5.3.

Analog Inputs

FX analog inputs are of line level format with a default input sensitivity of +4dBu (full output voltage swing/sensitivity) in all output modes. Input signal levels up to +24dBu can be handled without input clipping. Input sensitivity options are set via the amplifier network interface Input>Sensitivity menu. See Sections 6.1 or 5.2.

• Balanced input connections to the

amplifiers are made via male ‘Euro Block’ connectors. Connecting cables to the supplied female input connectors is illustrated in Diagram 8.2.

• Unbalanced input connections to the

amplifiers are made via RCA phone jacks.

Diagram 8.2: Balanced Input connections

Note: 2 channel amplifier model connections differ from 4 channel models only in the deletion of channel 3 and channel 4 output connectors. Input and GPIO connections remain the same between all FX models.

Digital Input/Output

FX offers a S/PDIF stereo digital audio input connection via a single RCA Phone jack.

A S/PDIF digital audio output jack is also fitted. The S/PDIF output signal by default reflects the input to amplifier installation zones A & B and is intended to be used for daisy chaining FX amplifiers.

Note: 75Ω RCA Phono cables specifically intended for digital audio should always be used for S/PDIF connections. Standard Phono cables can be used but may not result in optimal performance.

8.3 Output Speaker Connections

Output connections from the amplifiers are achieved via male ‘Euro Block’ connectors. Ensure that speaker connection polarity is correct throughout the installation:

• In the case of Low-Z

speaker connections, positive (+) amplifier terminals should always be connected to positive speaker terminals and negative (–) amplifier terminals always connected to negative speaker terminals.

• In the case of Hi-Z (70V or 100V)

speaker connections, the two speaker cable conductors should be connected between the positive (+) terminal of Output 1 and the negative terminal (-) of Output 2, and likewise for Outputs 3 and 4.

• Output mode options (Low-Z or Hi-Z)

are configured via the amplifier network interface in the Output>Speaker Preset>Output Mode menu.

Note: The exclamation point printed next to the output terminals of the amplifiers is, in addition to the CLASS 2 WIRING text, intended to alert users to the risk of hazardous voltages. Output connectors that could pose a risk are marked with the exclamation point. Do not touch the output terminals while the amplifier is switched on. Make all connections with the amplifier switched off. See Section 8.1 of this manual.

Operation

9. Operation

Once all connections have been made and configuration options selected, FX amplifiers are ready for use. If an input signal above -60dB is present on any input, the front panel Input and Standby indicators will illuminate green to indicate normal amplifier operation. Audio will be heard from any connected speakers.

Note: FX amplifiers will not switch on from Standby Mode unless an input signal is present or a network or external standby switch is operated.

Amplifier outputs will mute if no input signal is present for 5 minutes, and the amplifier will switch automatically to Standby Mode if no signal is present on any input for more than 15 minutes. Alternative standby and mute delay times can selected in the Settings>Power Management menu. Amplifier cooling fan speed is temperature controlled. The fan will switch off when the amplifier enters standby mode.

9.1 Front Panel LEDs

FX amplifier front panel indicators illuminate to indicate the following operational states:

• Status

Off – Mains power disconnected. Green – Amplifier operational. Pulse Green – Standby Mode. Amber – GPIO triggered Standby Mode

• Input

Off – No input signal present. Green – Signal present on one or more

inputs. Amber – Signal limiting/clipping on one or more inputs.

• Output

Off – No output signal present. Green – Signal present on one or more

outputs. Amber – Signal limiting/clipping on one or more outputs. Red – One or more channel pair is in overload/protection mode.

• Network

Off – No Ethernet network detected. Green – Ethernet network detected.

• WiFi

Off – WiFi disabled. Green – WiFi enabled.

9.2 Automatic Power Sharing

FX60 and FX125 amplifier models incorporate a power sharing feature that automatically shares the total power available from the amplifier’s internal power supply across each pair of output channels. If one channel temporarily demands more than the amplifier’s continuous power rating while other channel is demanding less, the excess power available from the internal power supply is automatically made available to the over-power channel.

Power sharing optimizes the amplifier’s ability to deliver maximum power into dynamic loudspeaker loads when playing music program material.

Note: On FX500 models, there is no significant power sharing capability.

9.3 Factory Reset

FX amplifiers can be reset using the following methods.

• Restart Device, In the configuration

Settings> Backup & Restore menu, there is a button called Restart Device. Performing a Device Restart does not erase any presets or data from the FX amplifier.

• Full Reset, In the configuration Settings>

Backup & Restore menu, there is a button called RESET! Clicking this button will permanently erase all device data and restore the unit to factory defaults. It cannot be undone.

• Hardware Reset, If unable to access the

amplifier's configuration interface through a network connection, it may become necessary to reset the device using the hardware reset switch. On the bottom side of the FX amplifier chassis, there is a small opening in the chassis at the center just behind the front panel. This provides access to the recessed factory reset switch.

1) To perform a complete factory reset using this switch, first remove AC power from the unit.

2) Use a pencil tip or similar item pressed through the rest switch opening, gently pressing the recessed momentary switch.

3) Apply AC power to the unit. Hold the

switch down for at least two seconds but no more than five seconds, then release the switch.

4) Remove AC from the unit, then reconnect AC. The unit will power up in the usual manner with factory default settings.
