5. OPERATION INSTRUCTION

5.1. Multiview Output Layout

PGM and PVW as Preview and Program displayed as following image. The level meter of PGM audio is

shown only in multiview. SDI/HDMI PGM out is without any overlays.

The following 6 windows come from the 6 input signals.

Page 9

The lower right corner display of the menu and status information. The CH1, CH2 are the channel

selection of the 2 audio sources for audio mixer. There is a real-time Digital clock/Analog clock displayed

beside the menu.

5.2. PGM PVW Switching

5.2.1. PGM, PVW Channel Selection

Below 1-6 buttons from PGM and PVW are corresponding with the 6 windows in the below of the

multiview layout. The selected button from PGM turns on to red LED, and the selected button from PVW

turns on to green LED.

The selected PGM source will circled in red border, while the selected PVW source will be circled in green

border.

For example, switching the PGM source to SDI 1 and PVW source to SDI 2. The button selection as

below.

Page 10

5.3. Transition Control

There are two transition control types for this video switcher: Transition without effects and Transition with

effects.

1) Transition without Effects

CUT performs a simple immediate switch between Preview and Program views. This is no delay

seamless switching and the selected transition effect WIPE, MIX or FADE is not used.

2) Transition with Effects

AUTO performs an automated switch between Preview and Program views. The timing of the transition is

set by the chosen speed button. The selected transition WIPE, MIX or FADE will also be used.

T-Bar manual transition performs like AUTO, but it is more flexible that the timing of the transition depends

on the speed of the manual switch.

5.3.1. FTB (Fade to Black)

Press FTB button it will fade the current video Program source to black. The button will flash to indicate

that it’s active. When press the button again it acts in reverse from complete black to the currently

selected Program video source, and button stop flashing. FTB is usually used for emergency condition.

Note: When the PGM window display black and keep black even after transition, please check if the FTB

button flashing. Press the button again when it is flashing to stop black.

5.4. Transition Effects

5.4.1. MIX Transition

Pressing the MIX button selects a basic A/B Dissolve for the next transition. When button LED turns on it

is active. Then use T-Bar or AUTO to operate the transition. The MIX transition effect as below

Page 11

5.4.2. WIPE Transition

WIPE is a transition from one source to another and is achieved by replacing the current source by

another source. Press the WIPE button and the LED turns on then it is active. There are total 8 WIPE

selections wiping start from different directions. Such as if choosing , then use T-Bar or AUTO to operate the transition, the WIPE effect as following:

INV button is an alternative button. Press it first and then press a Direction button, the WIPE will start from

an inverse direction.

5.4.3. FADE Transition

Fade is a transition from one source to another with fade gradually transition effect. Press the FADE

button and use T-Bar or AUTO to operate the FADE transition.

5.5. Audio Mixer Setting

5.5.1. Audio Description

This video switcher is coming with 1 channel 3.5mm Stereo audio & 1 channel RCA(L/R) analog audio

input & output and 4 channel SDI embedded audio.

5.6. USB3.0 Live Streaming

The USB3.0 streaming output transmits the PGM as an uncompressed Video and Audio signal. The

USB3.0 streaming output is based on UVC (USB video class) and UAC (USB audio class) standard. No

additional drivers need be installed. After installation in operating system, the relevant video and audio

devices will be added in the Windows Device Manager. There will appear two new devices:
