INTRODUCTION ENG 2 INTRODUCTION The Parrot is a high performance audio distribution amplifier with one stereo input and eight stereo outputs. It has many applications including tv and radio studios; editing rooms or where multiple loads (transmitters, amplifiers, recorders, etc) must be fed from a single audio source. The Parrot features both XLR balanced and PinRca outputs for an easier connection to either professional or consumer equipment.
SAFETY WARNINGS ENG 3 SAFETY WARNINGS A correct installation and an optimum level setting are crucial for a good operating and the exploitation of all the equipment capabilities. Please pay attention to the following notes: The installation and servicing instructions in this manual are for use by qualified personnel only. This symbol alerts you to the presence of dangerous voltage inside the closure – voltage which may be sufficient to constitute a risk of shock.
SAFETY WARNINGS 3.1 ENG AC MAINS VOLTAGE SETTING (220 V / 115 V) BE SURE THAT THE UNIT IS SET TO THE CORRECT MAINS/LINE VOLTAGE FOR YOUR COUNTRY BEFORE PLUGGING IT INTO THE WALL OUTLET. The actual Mains voltage is indicated on the silver label stuck on the right side of the Parrot closure.
SAFETY WARNINGS 3.3 ENG REMOVING THE TOP COVER To change any jumpers or set the voltage changeover you must remove the top cover of the unit to access the main boards. Remove all 6 screws holding the cover in place, then lift it off. Use care when working inside the unit. Uninsulated dangerous voltage are inside the enclosure, voltage that may be sufficient to constitute a risk of shock. Always disconnect to AC Mains before removing the top cover 3.4 • GROUNDING THIS EQUIPMENT MUST BE EARTHED.
EQUIPMENT DESCRIPTION ENG 4 EQUIPMENT DESCRIPTION 4.1 FRONT PANEL 1 TEST TONE OSCILLATOR SWITCH The Parrot contains an oscillator that can produce a sine wave tone at a 1 KHz / 0 dBm for system setup ad alignment. When TONE button is pressed (LED glowing), the sinusoidal TONE is placed on all the outputs (Out 1, Out 2, Out 3 and Out 4) by replacing the exsisting source signal. When released, the audio distributor returns to its previous state (normal operation).
EQUIPMENT DESCRIPTION 4.2 ENG REAR PANEL 1 ON/OFF Switch: main ON/OFF switch, the LED inside switches on/off accordingly. The power supply socket (use the cord provided) has a built-in fuse drawer containing the power fuse and a spare, both of the same value: for 220/230 V AC the fuse is rated at 630mA T; for 110 V AC voltage it is rated at 1 A T. 2 XLR outputs # 2, 3 and 4. They are electronically balanced.
CONNECTIONS AND SETTINGS ENG 5 CONNECTIONS AND SETTINGS We suggest to use high quality wires, well protected, and balanced connections to avoid external EMD. If ground loop problems are encountered, never disconnect the mains earth, but instead, try disconnecting the signal screen on one end of each of the cables connecting the outputs of the Parrot to the loads. If such measures are necessary, balanced operation is recommended. 5.
CONNECTIONS AND SETTINGS 5.3 ENG MONO / STEREO INPUT MODE Using the Stereo input setting, both Left and Right signals are directed to their respective output paths. In the Mono input configuration the Left input signal is replicated on the Right internal bus, while the Right input connector is disconnected. Thus, provide the LEFT channel only. See Block Diagram - Chapter 6.
CONNECTIONS AND SETTINGS 5.5 ENG AUDIO OUTPUTS The equipment features balanced XLR and unbalanced PinRca analog outputs driven by high-quality buffers and capable of withstanding even low-impedance loads (600Ω), with levels of up to +20 dBu. In case of unbalanced connections, connect the cold pole (Pin 3) to the ground (Pin 1) or use the PinRca unbalanced outputs.
