Thank you for your purchase of the ARC-HP. The ARC-HP is designed for two purposes
1) ADDITIONAL HEADPHONE OUTPUTS - To provide additional headphone outputs for your console.
You may use one or more units 'daisy chained' and have multiple headphone outputs.
2) LOGIC & AUDIO INTERFACE – The ARC-HP has two buttons, Talkback and Cough. These buttons,
along with other logic allow you to interface to your console.
HEADPHONE SETUP INSTRUCTIONS
STEP 1 – Connect the Main Studio console audio output (such as Program, or Monitor output) to the
audio Main input on the ARC-HP. The Main input is a balanced input that uses pins 1, 2, 3, and 6.
MAIN PORT PINOUT
1 - PGM L+
2 - PGM L-
3 - PGM R+
4 - GND
5 - TB (Control) Pulling to Ground triggers TB relay
6 - PGM R-
7 - TB Audio In +
8 - TB Audio In -
STEP 2 (OPTIONAL) – Connect the Main Studio Talkback
audio output to Pins 7 & 8 on the ARC-HP Main input.
For example, the ARC-10 series boards have a DB15
connection, and Talkback audio fed from Mic's 1 & 2 are
fed from the DB15 pin 12 (check ARC-10 manual for
current information).
This allows the Main studio to Talk to the user on the ARC-HP.
STEP 3 (OPTIONAL) - Connect the ARC-HP Main input, pin 5, to the Main Studio's console logic. When
pin 5 on the ARC-HP is pulled to ground, it will
(A) duck the PGM audio on the ARC-HP, and
(B) play the TB Audio from the Main studio.

STEP 4 (OPTIONAL) – If you have additional ARC-HP units, and would like to connect them to the Main
Studio, simply connect the Parallel output from the main ARC-HP unit to another secondary ARC-HP
unit's Main input.

STEP 5 – Connect your headphones to either the 1/4” or 3.5mm headphone jacks on the front of the
ARC-HP.
IMPORTANT NOTE The ARC-HP is designed to be used with contemporary high-efficiency
headphones (24 – 600ohm), not 8ohm headphones.
STEP 6 – Connect the power supply (supplied with the ARC-HP unit). Be sure to only use the supplied
AC power supply provided by Arrakis. Use of any other supply will likely destroy the unit, and void your
warranty. The power supply works with 110V outlets only.
COUGH FUNCTIONALIT
STEP 7 (OPTIONAL) – Add 'Cough' functionality to the ARC-HP. Connect your mic audio to the Control
I/O on the ARC-HP. This port is balanced, and uses pins 7 & 8.
STEP 8 (OPTIONAL) – Connect output pins 3 & 6 of the Control I/O to your Main Studio console mic
input.
This allows the user to press the Cough button on the front of the ARC-HP, which will mute the mic
audio. The switch is momentary, so press to cough, and then let go to restore mic audio.
This switch is Normally Closed, but when the Cough button is pressed, it will make the switch Open.

audio output to send to a connected studio's console input.
