Frequently Asked Questions - AVN-PX8 Sonifex

How do I properly clean the hand blender after use?

Unplug the blender and detach the shaft. Rinse the blade and shaft under running water or place them in the dishwasher. Wipe the motor body with a damp cloth. Do not immerse the motor body in water.

Can I blend hot liquids directly in a pot?

Yes, but allow the liquid to cool slightly to avoid splashing. The stainless steel shaft is heat-resistant, but never submerge the motor body.

What should I do if the blender stops working while in use?

Check if the safety lock is engaged. Ensure the power cord is plugged in and the outlet is functional. If it still doesn't work, let the motor cool down for 10 minutes; it may have overheated.

Is the blade assembly removable for replacement?

Yes, the blade assembly is detachable. Replacement blades can be ordered from Sonifex or authorized dealers.

Can I use the blender for crushing ice?

This hand blender is not designed for crushing ice. It is intended for blending soft foods and liquids. Using it on ice may damage the blades.

What is the maximum operating time before a break is needed?

The blender should not be operated continuously for more than 1 minute. Allow at least 1 minute of rest between uses to prevent motor overheating.

How do I attach the blender shaft securely?

Align the shaft with the motor body and push until it clicks. Ensure the release button is flush. A slight twist may help lock it in place.

The blender vibrates excessively during use. What's wrong?

Check if the blade is properly attached and not bent. Also ensure the food is not too chunky. If vibration persists, reduce speed or blend in shorter pulses.

Can I use the blender in a non-stick pot?

Yes, but avoid scraping the bottom of the pot with the blade. Use gentle circular motions to prevent scratching the non-stick coating.

What voltage does the AVN-PX8 support?

The blender supports both 120V and 230V mains voltage, but you must check the rating on the product label. A voltage selector switch may be present.

1. Sonifex Presenter Mixer System Manual

Overview

The presenter mixer system allows on-air presenters to adjust the audio levels fed to their radio or wired IEM systems, whilst also allowing Sound Control Room operators to adjust the levels remotely. The system consists of 3 types of unit all connected on a common Ravenna Audio over IP (AoIP) network with added audio sources derived from Ravenna based AoIP mixers or input portals. Setup and control can be provided via webpages and/or 3 applications. The system uses mono audio throughout.

The 3 units are:

• AVN-PX8x4C - a 2U rack mounted Mix Engine Rack.
• AVN-MPPR - a small desk, or microphone stand, mounted Presenters' Remote Unit – aka PRU.
- AVN-MPTR - a 1U rack mounted Technicians' Remote Unit - aka TRU.

The Mix Engine, as well as using AES67 audio streams, accepts 24 an optional that both MPTRs could also select the same VM so a maximum of 6 mono input channels on 3 x DB25 connectors and output 16 analog devices can control the mix levels of a VM.

channels on 2 x DB25 connectors. Each mixer unit is able to create and control 8 virtual mixers, each capable of mixing any 4 sources (analogue or AoIP) to a single mixed output that is available locally at an output and via an AoIP stream (to the Presenter Unit and other destinations). The analogue audio line-up level will default to +18dBU = 0dBFS. The Mix Engine will allow a maximum of 32 audio over IP input streams (each stream can be up to 8 channels). There are 8 virtual mixer outputs available. Each Virtual Mixer has 4 sources and 1 mixed output. There are also 2 more monitor outputs which play out the audio of the VM selection made on each of the 2 connected Technician Remote Units.

A built-in webserver is used for configuration settings, input/output and for defining which Presenter and Technician Remote Units are to the particular Mix Engine and Virtual Mixers. Up to 4 MPPRs can be assigned to each Virtual Mixer on a first-come first-served basis. It's

The Mix Engine has dual universal AC power supplies which are hot-swappable assigned in the event of failure and have a green LED to indicate within spec operation. The front panel has LED indications and GPOs to warn of power supply failure. There are also front panel LEDs for network and sync/clock failure.

Front Panel Controls

Status LEDs

On the left side of the panel, there are a number of status LEDs used to provide a basic overview of various system parameters such as power supply failure, network and sync/clock failures.

Each of these LEDs can be illuminated in different combinations of and flashing or non-flashing states. The table below provides an over what each LED state signifies.

Led Name	State Description

Network Ports

The Mix Engine has 2 network ports; the primary port is the AoIP p is mainly used for the transport of audio - between the Mix Engine MPPRs, and between the Mix Engine and the Main Studio Mixing De network will also provide connection for discovery of devices and Em control, status and metering information.

The control port will provide webserver access to settings. This port intended to run on a physically different network, so engineers/operat can interrogate/set device parameters on the system without their net overhead impacting on the AoIP network. The webserver can also be accessed via the AoIP port.

Standard GPIO Connector

This is a 15-way female 'D'-type connector which has 10 ports with pin assignable direction & function, and a voltage free relay switched output with normally open and normally closed contacts. The Technician and Presenter Units have a single connector, and the Mix Engine has two of

these connectors, allowing 20 x GPIO and 2 x relay closures.

Pin Number Description
Pin 1 GPIO 1
Pin 2 GPIO 2
Pin 3 the GPIO 3
Pin This GPIO 4
Pin 5 GPIO 5
Pin 6 Relay - Normally open contact

Pin 14 Fused (200mA) +12V DC supply
Pin 15 Ground

When the pin is defined as an input then the pin should be pulled to ground to activate it. When the pin is defined as an output then when the output is active the pin will be pulled to ground – and is capable of sinking 20mA.

Analogue Audio Inputs & Outputs

The audio inputs and outputs on the mix engine are all on 25-way female 'D'-type connectors. (Note the same connector type for both inputs and outputs) so that standard Tascam analogue (AES59) cables can be used.

Audio Levels and dBFS equivalences

Each of the analogue inputs and outputs can be configured to set the desired 0dBFS line-up level. By default, this setting is 0dBFS = +18dBu, for operation in most European countries, however this can be modified to one of the following values: +12dBu, +15dBu, +18dBu, +20dBu, +22dBu or +24dBu, to match global requirements. This setting is changed via the web browser, by clicking Configuration >Audio Config >Physical Audio Setup (see section 7 Audio Config -> Physical Audio Setup Web Page)

Fig 3-1: AVN-MPPR Front and Rear

The MPPR Presenter Remote Unit - also known as the PRU, will provide control levels to the virtual mixer, and display the status information and data generated by the mixer. The virtual mixer audio output will be available on the rear panel Mix Output or via headphone outputs on the front panel.

Front Panel Controls

Status and Mixer ID LEDs

On the left side of the panel, there are a number of status LEDs at the word "Mixer" there is also an indication of the virtual mixer being controlled. When the unit has been grabbed by a mix engine and to a virtual mixer, the appropriate LED will be illuminated to indicate virtual mixer currently under control. If the unit is not currently assigned a virtual mixer, the Mixer ID LEDs will all flash red to indicate that case.

There are also a number of status LEDs which are used to provide overview of various system parameters. A software enabled limiter on Virtual Mixer output is configured to prevent audio over-hitting. When limiter is operational, the front panel Limit LED illuminates red. The panel also has LED indication to warn of power supply failure, network sync/clock failures.

Each of these LEDs can be illuminated in different combinations of c and flashing or non-flashing states. The table on the next page provides what each LED state signifies.

Rotary Controls

The rotary encoders on the front panel act as level controls for the sources assigned to the virtual mixer that the unit is currently controlled. Turning the encoder will increase/decrease the mix level by 4dB per 100 MHz from Mute, then -80dB up to -60dB, switching to 2dB per step up between -60dB and a maximum of +10dB gain. The total number of 41 which represents just under 2 complete rotations and will be shown in the level display by the 21 LEDs. This level is shown on the scale I LED pattern, so that initially LED 1 will be lit then LEDs 1 & 2, then only then LEDs 2&3 etc, so we have a total of 42 states between maximum.

Headphone sockets

XLR Mute

By default, the audio on the XLR output on the rear of the unit is not when headphones are connected to one of the sockets on the front of unit. However, there is a "Headphone XLR Mute" configuration setting in the "Misc Settings" section of the webpages to enable the muting of the XLR output on headphone connection if required.

Attenuation

The headphones will have an additional software-configurable output level control (one for each headphone output) to set the attenuation of the signal to the headphone driver for comfortable levels at normal signal level data of from the output. At present we know of 3 headphone types - 120 Ohm rotary (default), 2 kOhm (high impedance), and 8 Ohm (low impedance). The maximum output of the headphone drivers is +12dBu so the minimum

curatenuation parameter is 6db, which is present for all headphone types. The "Alteratuation parameter will act as a second attenuation and will have a againrange from 0 to 24dB – the latter value will be chosen to provide suffi range to easily cater for the lowest impedance headphones. The "6.35mm Att." and "3.5mm Att." attenuation settings can be set via the web page at the front of the Misc Settings" section.

ToPentebutton

The button between the Mixer LEDs and the rotary controls provides a virtual GPO from the unit that can be used on the Mix Engine to trigger its remote port. This button will illuminate red when it has been LEDed by this MPPR and will be yellow when initiated by a paralleled control or MPTR. A MPPR can only de-assert a GPO that it has originally assessed. However, the GPO can always be de-asserted by a MPTR. The selection of the GPO is determined by the VM that the MPPR is current connected - VM1 maps to GPO1 and so on to VM8, which maps to GP. The text on the button is a plastic insert so can be changed to suit your particular application.

We are using a protocol called Ember+ for the IP control so all control and status messages are available to third parties using Ember+.

There is a simple app (EmberPlusViewer) for a Windows PC that can be invoked to show this functionality and Ember+ is a freely usable protocol. We will publish relevant schemas as we develop them, with full specifications of the parameters used.

Control Precedence

The Mix Engine has a webserver that is used to access the system settings for the Virtual Mixers and for the associated Remote Units. When a Remote Unit comes online and is authorised then it will advertise itself as being available to the network using mDNS messages. The Mix Engine will receive

these messages and determine if the device 'belongs' to a Virtual Mixer However it may be that MPTRs will want to take away the level control MPPRs, (see sections 3, Rotary Controls, and 4, Mixer Selection Buttons)

6 Operational Specification

Group/Studio Assignment

The MPPRs are normally assigned as a studio to a group and that studio is closely aligned with a gallery which contains a Mix Engine and 1 or 2 MPTRs. To 'move' a studio from one gallery to another, the user will need to de-allocate the group from one Mix Engine and assign it to another. The Grab function does this automatically, though in a managed system it would be good practice to release a group from one Mix Engine before grabbing it in another.

To do this Mix Engine that has current ownership of the group will need to relinquish that control by entering the menu or web page on a MPTR (or Mix Engine) and going to the Assignment. Select the group to be released and allow it to be de-assigned. Now the other gallery MPTR (or Mix Engine) can perform a similar function, but this time select the group and grab it.

Operational Specification 6

Configuration

- System Parameters.

The normal configuration is done via a webserver on the Mix Engine. ThisButton actions and timeout for metering/level on remote level will allow the user to define everything about the Mix Engine, its Virtualcontrols.

Mixers and the Remote Units connected to it, with the following settings: Headphone attenuation settings.

• Network Settings.
- Connectivity.

* Number of Virtual Mixers and their associated ID.
* Incoming audio channels by connector and port.
* Outgoing audio channels by connector and port.
* Selected AoIP input channels.
* Creation of outgoing AoIP output sources.

- Naming.

* The unit itself with ID number.
* The Virtual Mixers.
* The analogue input sources.
* The AoIP sources if the Ravenna name is not sufficiently informative.

• Virtual Mixer Setups by Number (1-8).

* The 4 input sources used.
* Output routing.
* GPIO port setup.
* Controls enabled/disabled at individual control level.
* Sharing settings for other Presenter and Technician Units.

• GPIO Interconnection Map.
- Unit Parameters.

* MPPR headphone attenuation x 2
* LED brightness settings

System Parameters should be the same for all Mix Engines, so changing setting on one Mix Engine will cause the parameters on all Mix Engines be altered, and as new Mix Engines are connected to the system, they fetch the current settings from an active Mix Engine. Equally as new MP and MPTRs are connected they will fetch the appropriate info from their connected Mix Engine and update global parameter values used by them.

The webserver pages will also allow firmware updating of local and remo units either on connection or on webpage command.

Finally, there will be 2 configuration file options.

1. To save and recall the complete setup, as above, to or from local memory on a PC. This is so that if a Mix Engine unit is replaced, can immediately upload the settings to a new unit which should include the network settings.

2. A partial load for system wide parameters to ensure that changes can be uploaded from other Mix Engine units within an installed system, but without changing the local network settings.

Using both Grab - to add a group to an unused group 3: R + D

and release to free a group from an assigned slot

will cause a double confirmation dialog with the Group Slot 4: Long group alias val

second dialog swapping the Yes No positions to

absolutely ensure that the new group assignment Fig. 7-13: Group Config ->Group Assignments Web Page

is what the user wants. In later software there will

be information about groups that are assigned

elsewhere as the grab function will automatically

remove the group from other mix engines as it is

grabbed locally.

Confirmation Required...

This will grab Studio 3 and assign it to Group Slot 2.

Do you want to continue?

If another Mix Engine is already assigned to a

group it normally is forced to release it when the

user selects a group here, but if the Mix Engine is

disconnected from the network or de-powered

then this cannot happen. Consequently when this

other Mix Engine is connected there will be a clash

as both Mix Engines will want to have control of

the group. In this case the newest Mix Engine will Fig 7.14: Confirmation Dialog

fail to gain control and a message will be shown on

its front panel and the above screen will show

RESOLVE instead of RELEASE. Pressing this will

allow the user to relinquish control of the group or

grab the group and force the other Mix Engine to

relinquish control.

System Web Page

The system web page allows the user to update the firmware ; to save and load complete configurations from saved files; and to save the system log to a file for examination of fault and conditions. The new firmware will have to be available on the connected PC. These files are downloadable from the Sonifex website – www.sonifex.co.uk and will have an .swu suffix. The upgrade will take around a minute to complete. If the upgrade fails, then there is a fallback recovery system that is permanently available to the unit, which will cause the unit enter a default IP state which can be accessed from a browser at a URL of http://192.168.0.100:8080 Again select the .swu file and click the upgrade button.

The front panel has its own firmware, and this is embedded into the main code above. If the unit starts up an recognises that the front panel code in the firmware is a different version to that currently stored in the front panel then the main board will perform an update on the front panel. It does this by restarting the front panel in a bootstrap mode where the status LEDS 1&2 and 3&4 will flash alternately and where the display will show a progress bar for the update of around 30 seconds. The front panel can be forced into bootstrap mode by holding down the centre ok button and the bottom arrow on the roundel navigation control during a power or reset cycle.

The display and roundel on the front page allows the user to perform a subset of the functions available on the web pages. It is a little more cumbersome than the web pages as data entry is not as simple without a keyboard, but for an occasional, or emergency change to the setup it is quite usable. The table above shows the structure of the menu screens. The menu is entered by pressing and holding down the roundel centre button – which can be also considered as the enter button – or by pressing the MENU fast key. Use the up and down buttons, or the spinwheel to move to the desired menu selection and then press the enter button. At this level the left button acts like a back key and will move back through the menu structure. And the MENU fast key will exit the menu or sys info and return to the main screen.

Eventually the user will enter either a list of options – with the active option ticked, or will enter a dialog where a parameter can be changed. In a list move the selection to the new choice and press the enter button, followed by moving to the back or close option to exit the list or use the left button to step back along the menu structure. In dialogs the user will have exit options – usually YES/NO or OK/CANCEL use the left and right keys to move between these actions and the press the enter button. If there is a parameter to be changed use the up and down buttons to move between the parameter and the exit options. In the parameter the spinwheel allows the user to change the highlighted element until the setting is correct when a down key followed by the YES or OK option will update the parameter.

The three group config menu selections can be entered directly by pressing the appropriate fast key when the main screen is shown.
