Analog Audio Distribution Amplifier User Guide BrightEye 33 TM PRODUCT OVERVIEW BrightEye 33 is a high performance audio distribution amplifier for the broadcast and recording industry. Exceptional performance features include excellent response, noise and distortion specifications. BrightEye 33 functions with either 8 mono outputs or 4 stereo outputs. Gain adjustments are accessed from the front panel. This is a simple device with no USB port and no interface to BrightEye Mac or PC software.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM REAR CONNECTORS All connections to the BrightEye 33 are made on the rear of the unit. Refer to the illustration below. BrightEye 33 Rear Connectors Power Connection Connect a modular power supply to the 12 volt DC power input connection on the far left of the unit. Use the locking ring to secure it. Analog Audio Input This 6-pin Phoenix connector provides two channels of analog audio input.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM For Unbalanced Audio to a RCA Phono Input To connect the audio output to a consumer audio connector such as an RCA phono jack, connect the pins as follows: • Attach Ground from Pin 1 of the Audio Out to the shell, Shield or Ground of the RCA Phono jack. • Attach the + (plus) signal from Pin 2 of the Audio Out to the center pin of the RCA Phono jack. • The – (minus) signal is not used in this application.

Analog Audio Distribution Amplifier User Guide BrightEye 33 TM GLOSSARY This is a brief glossary of commonly used terms associated with this product. AES/EBU The digital audio standard defined as a joint effort of the Audio Engineering Society and the European Broadcast Union. AES/EBU or AES3 describes a serial bitstream that carries two audio channels, thus an AES stream is a stereo pair. The AES/EBU standard covers a wide range of sample rates and quantizations (bit depths.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM Chroma The color or chroma content of a signal, consisting of the hue and saturation of the image. See also Color Difference. Component In a component video system, the totality of the image is carried by three separate but related components. This method provides the best image fidelity with the fewest artifacts, but it requires three independent transmission paths (cables).
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM EDH Error Detection and Handling is a method to verify proper reception of an SDI or HD-SDI signal at the destination. The originating device inserts a data packet in the vertical interval of the SDI signal and every line of the HD signal which contains a checksum of the entire video frame. This checksum is formed by adding up the numerical values of all of the samples in the frame, using a complex formula.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM lines are transmitted in the first field, the even-numbered lines are in the second field. In this way, the repetition rate is 50 or 60 Hz, without using more bandwidth. This trick has worked well for years, bit it introduces other temporal artifacts. Motion pictures use a slightly different technique to raise the repetition rate from the original 24 frames that make up each second of film—they just project each one twice.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM Optical An optical interface between two devices carries data by modulating a light source. This light source is typically a laser or laser diode (similar to an LED) which is turned on and off at the bitrate of the datastream. The light is carried from one device to another through a glass fiber. The fiber’s core acts as a waveguide or lightpipe to carry the light energy from one end to another.
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM ScH Phase Used in composite systems, ScH Phase measures the relative phase between the leading edge of sync on line 1 of field 1 and a continuous subcarrier sinewave. Due to the arithmetic details of both PAL and NTSC, this relationship is not the same at the beginning of each frame. In PAL, the pattern repeats ever 4 frames (8 fields) which is also known as the Bruch Blanking sequence. In NTSC, the repeat is every 2 frames (4 fields).
Analog Audio Distribution Amplifier User Guide BrightEye 33 TM Tri Level Sync An analog sync reference signal that is used in High Definition systems. Tri Level Sync is constructed with three signal levels, the sync pulses extend above and below a mid-level average voltage (the blanking level). Unlike conventional analog sync which is bi-level, the proper 50% pickoff point is already identified in Tri Level Sync. This contributes to lower jitter in digital systems.
