AC Power Switch
-
Power Indicators:
-
PSU A – Illuminates when an AC input is applied and all DC outputs are present.
-
PSU B – Illuminates when an AC input is applied and all DC outputs are present.
When both supplies are functioning and have AC inputs PSU A will be the default supply.

-
RedNet Network Status Indicators:
-
PRIMARY – Illuminates when the device is connected to an active Ethernet network. Also illuminates to indicate network activity when operating in Switched mode.
-
SECONDARY – Illuminates when the device is connected to an active Ethernet network. Not used when operating in Switched mode.
-
LOCKED – Illuminates when a valid sync signal is received from the network, or when the RedNet A16R MkII unit is the Network Leader. Flashes if the external clock is selected but not connected.

RedNet Sample Rate Indicators
Five orange indicators: 44.1 kHz, 48 kHz, x2 (multiple of 44.1 or 48), x4 (multiple of 44.1 or 48) and sample rate PULL UP/DOWN. These Indicators illuminate individually or in combination to indicate the sample rate being used. For example, for a 96kHz Pull Up/Down setting, the 48kHz, x2 and Pull Up/Down indicators will illuminate.
-
Signal Level Indicators:
-
INPUTS – Tri-colour LEDs indicate audio signal levels at the inputs to the network:
-
Green: Signal present (illuminates at -42dBFS)
-
Orange: -6dBFS
-
Red: 0dBFS
-
-
OUTPUTS – Tri-colour LEDs indicate audio signal levels at the outputs from the network:
-
Green: Signal present (illuminates at -42dBFS)
-
Orange: -6dBFS
-
Red: 0dBFS
-
Note
When operating at quad sample rates, the indications for LEDs 15 and 16 will depend on the signal mode selected.

AES3 Signal Presence Indicators
Green LEDs indicate if an AES3 signal is present IN to the network, and OUT from the network; each illuminates at -126dBFS.
Note
When operating at quad sample rates, the IN and OUT LEDs don’t illuminate if Analogue mode has been selected.

Clock Source
Three orange indicators: Internal, Word Clock (BNC input) and DARS (XLR-3 input). Whichever is lit identifies the clock reference being used. When an incoming clock source is invalid, the ‘Locked’ indicator will flash to indicate that the unit has reverted to using its internal clock.
None of the indicators will be lit when the device is a operating as a Dante Follower.
-
IEC Mains Inlet A
Standard IEC receptacle for AC mains. RedNet A16R MkII features a ‘Universal’ PSU, enabling it to operate on any supply voltage between 100 and 240 V AC
-
IEC Mains Inlet B
Input connector for backup mains power source. Power supply B remains on standby but will seamlessly take over if PSU A develops a fault or loses its main input supply.
If an uninterruptable power supply (UPS) is available, it is recommended that this is applied to inlet B.
-
Primary Network Port
RJ45 etherCON connector for the Dante network. Use standard Cat 5e or Cat 6 network cables to connect RedNet A16R MkII to the Ethernet network switch. Adjacent to each network socket are LEDs which illuminate to indicate a valid network connection plus network activity.
-
Secondary Network Port
Secondary Dante network connection where two independent Ethernet links are being used (Redundant mode), or an additional port on an integral network switch on the primary network (Switched mode).
-
Word Clock Out
Provides an output of the chosen system clock reference (can be switched between the base rate or network rate).
-
Word Clock In
Allows synchronisation of the Dante network to house word clock.
-
AES3 Out
Permanent AES3 output of audio channel pair 17-18.
When operating at quad sample rates, channels 17-18 become duplicates of channels 15-16. The output is always available when operating in either AES3 or Analogue mode.
-
AES3 In
AES3 source for channels 17-18. May also be used as a clock source when fed with either AES3 or DARS (Digital Audio Reference Signal – AES3 distributed clock as per AES11). Software selectable.
-
DB25 Analogue Connectors
Analogue inputs and outputs on DB25 female connectors; eight channels per connector. Wired to the AES59 analogue standard (also known as the Tascam standard).
RedNet A16R MkII requires 1U of vertical rack space. Allow an additional 75mm of rack depth behind the unit to allow for cables.
RedNet A16R MkII weighs and for installations in a fixed environment (eg., a studio rack), the front-panel rack mountings* will provide adequate support. However, if the unit is to be used in a mobile situation (eg., flight-cased for touring, etc.), it is recommended that side support rails or shelves are used within the rack.
Important
*Always use M6 bolts and cage nuts specifically designed for 19” equipment racks. An Internet search using the phrase “M6 cage nuts“ will reveal suitable components.
Cooling is by fan assistance from side to side. The fans used are low-speed and low-noise.
Note
The maximum operating environmental temperature is 45°C / 113°F.
Ventilation is via slots in the enclosure on both sides. Do not mount RedNet A16R MkII immediately above any other equipment which generates significant heat, for example, a power amplifier. Also, ensure that when mounted in a rack, the side vents are not obstructed.
RedNet A16R MkII is mains-powered. It incorporates ‘Universal’ power supplies which can operate on any AC mains voltage from 100V to 240V. The AC connections are made via standard 3-pin IEC connectors on the rear panel.
When PSU A and PSU B are both connected, PSU A becomes the default supply and therefore draws more current than B. If a backup mains supply is provided from an uninterruptable source, it is recommended that this is connected to input B.
Mating IEC cables are supplied with the unit; these should be terminated with mains plugs of the correct type for your country.
The AC power consumption of the RedNet A16R MkII is 41 W.
Note
There are no fuses in RedNet A16R MkII or other user-replaceable components of any type. Please refer all servicing issues to the Customer Support Team (see Customer Support and Unit Servicing).
