AES/EBU & Analogue Combined Line Output
The line output is an XLR 3 pin male connector with the following

balanced analogue or AES/EBU audio by following the input, i.e. a
digital input produces a digital output.

Pin 2: Phase
Pin 3: Non-Phase

balanced floating). It is autosensing for either analogue balanced or
AES/EBU (left channel) signals.
Pin 1: Screen
Pin 2: Phase
Pin 3: Non-Phase
Mic/Line Input Select Switch
This push-button switch sets the input signal mode:
Switch depressed (in)
- Mic input mode selected
Switch not depressed (out) - Line input mode selected
Adjusting the Microphone Gain Level
The Mic Level preset potentiometer controls the level of the input
signal when the Mic/Line Input Select Switch is set to Mic input. The
input signal level in Line mode is factory set and is not affected by this

is balanced/floating with a maximum gain of 70dB. Use a jeweller’s
screwdriver to adjust the gain between 65dB and 35dB. The gain
range can be extended by ±6dB by using the front panel ‘Level to The
Line’ switch.
Remotes
The remote port allows you to control the line hold circuit from a mixing
desk or other remote device and also outputs opto-isolated outputs to
indicate the line hold status and the DTMF detect function.
The remote connector is a 9-way female (socket) ‘D’ type. To remotely
control the line connect, connect pin 1 to pin 2. The action of this remote
can act as momentary or latching by pin 6 having no connection or
connecting to 0V respectively.
Pins 3 & 7 are an opto-isolated remote line connect indicator and pins 5 & 7
are an opto-isolated DTMF detect output. They can use the local supply pins
4 & 8 to drive an LED indicator or a low current load.
Pin 1: Remote Line Connect Switch
Pin 2: Common – 0V
Pin 3: Opto-Isolated Line Connect Indicator - NPN Emitter
Pin 4: Common – 0V
Pin 5: Opto-Isolated User GPO (DTMF Detect*) Indicator - NPN Emitter
Pin 6: User GPI (Momentary/Latch Line Connect Switch - connect to
0V for latching action*)
Pin 7: Opto-Isolated Line Connect Indicator - NPN Collector
Pin 8: 5V out (current limited supply for pins 7 & 9)
Pin 9: Opto-Isolated User GPO Indicator - NPN Collector
The remote line connect indicator mimics the front panel Line Hold/
Connect Switch lamp, i.e. it flashes when ringing and is on when the line is
held.
*These GPO and GPI default functions are set to the same as the fixed GPIO
functions of the DHY-03.
Conference Audio/Record Output
This is an RJ45 analogue audio connector to cross connect to another DHY-
04G/HD. This will allow a single TBU channel on a mixing desk to handle 2
calls, one to each DHY-04G/HD. Alternatively the conference output signals
