Important Safety Instructions

1) Read these instructions.

2) Keep these instructions.

3) Heed all warnings.

4) Follow all instructions.

5) Do not use this apparatus near water.

6) Clean only with dry cloth.

7) Do not block any ventilation openings. Install in accordance with the manufacturer's instructions.

8) Do not install near any heat source such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

9) Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for replacement of the obsolete outlet.

10) Protect the power cord from being walked on or pinched, particularly at plugs convenience receptacles and the point where they exit from the apparatus.

11) Only use attachments/accessories specified by the manufacturer.

12) Use only with the cart stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13) Unplug this apparatus during lightning storms or when unused for long periods of time.

14) Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as when power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15) Do not expose this apparatus to rain or moisture.

16) The apparatus shall be connected to a mains socket outlet with a protective earthing connection.

CAUTION!

In products featuring an audio amplifier and speakers, the surface at the side of the unit, where the audio amplifier heat sink is internally attached, may get very hot after extended operation. When operating the unit excercise caution when touching this surface and ensure that external materials which may be adversely affected by heat are not in contact with it. There is a Hot Surface label (see diagram) attached to the aforementioned surface of the product.

Unpacking

Unpack the AVMFlex-SA Series unit from the shipping container and inspect all articles for shipping damage. If you find any damage, notify the shipping carrier immediately for claims adjustments. Compare the shipping box contents to the packing slip. Contact a PANORAMAdtv sales representative if there are any unexplained shortages.

Heat Dissipation

Heat dissipated by the speaker amps is conducted directly to the left side of the chassis; no special considerations for cooling are necessary as long as the ambient temperature inside the rack area does not exceed approximately 40°C (104°F).

Sympathetic Vibration

Sympathetic vibration from other equipment (cables, etc.,) in the rack may be serious enough to interfere with the unit’s sound quality out in the listening area. The use of thin card stock and/or felt or foam weather-stripping type materials between adjacent vibrating surfaces, or tying up loose cables, etc., may be required to stop vibrations external to the unit.

Audio Connections

Connection of the audio feeds is straightforward. Please refer to the system interconnect block diagrams on page 26 for clarification of the general signal paths into and out of the AVMFlex-SA Series units.

Rack Mounting

The AVMFlex-SA Series unit rack mounts in a standard EIA-310-D specification 19”/483mm rack and needs 1RU of space. Allow sufficient space at the unit rear for connector and cable clearance (approximately 4”/102 mm). The AVMFlex-SA Series unit rack mounts

from the front panel support rails. Rear support is not required.

Cable Recommendation

Recommended cable type for analog video signals is: Belden 8281, Belden 1694A, or equivalent. Recommended cable type for analog audio signals is: Belden 9451 or equivalent.

AVMFlex-SA Series

1U Audio/Video Monitor

AVMFlex-SA/4 Front Panel

Description

The AVMFlex-SA Series of audio/video monitors provides the capability to monitor CVBS (composite analog) or SDI (serial digital interface) video on an LCD display with full-fidelity stereo audio monitoring in a single rack space (1U). The AVMFlex-SA Series models feature a VPOD LCD video display module mounted to the front panel via a flexible gooseneck allowing for extensive control of the viewing angle.

All models in the AVMFlex-SA Series contain four high performance speakers driven by three power amplifiers: two amplifier/driver combinations handle midrange and high frequency information in stereo, while the third center channel reproduces information below the 500 Hz crossover point. Output limiter circuits are incorporated to protect the speakers.

The VPOD LCD Video Display is available in 4", 5.6", 5.8" (16:9), 6.8", and 7" (16:9) LCD sizes and features controls for color, tint/hue (NTSC only), contrast, and brightness. The display also has a power LED of its own and a bi-color (red/green) tally indication LED.

All AVMFlex-SA Series models come equipped with two 10-segment tri-color (red/amber/green) LED bargraph display level meters, separate volume and balance controls, a power indication LED, headphone output, and an SDI lock status LED display, which visually shows the lock status of SDI signals selected for monitoring. Extensive magnetic shielding allows placement immediately adjacent to video monitors with no color impurities.

The AVMFlex-SA Series rear panel is configured with one CVBS video input with loop-through output on BNC connectors, one SDI video input and re-clocked output on BNC connectors, one CVBS video output de-embedded from the SDI input on a BNC connector, two balanced (stereo) analog audio inputs on XLR connectors, two balanced analog audio outputs de-embedded from the SDI audio input on XLR connectors, and two analog outputs of the selected audio source on two male XLR connectors. The audio and video inputs are relayed so that selecting either the CVBS or SDI video source on the VPOD video display module will also select the associated CVBS or SDI audio source. A DB-25 connector is also provided for tally connections.

Section 2: Operation

Front Panel Features

Please refer to Figure-2a on the facing page to familiarize yourself with the front panel features of the AVMFlex-SA Series unit. The following sections describe these functions and are referenced, by number, to Figure-2a.

Speakers

The internal speaker system is comprised of two mid-range tweeter speakers (left and right) and two woofer speakers (left and right). The two mid-range speakers reproduce only the mid and high frequencies, while the two woofer speakers monaurally reproduce the low frequencies. See page 18 for more information about the audio amp and speaker configuration.

Headphone Output Jack

This jack accepts a standard 1/4” phone type stereo plug. Select the headphone audio sources as you would for the internal speakers. When you plug in headphones, the speakers will mute.

SDI Group Select Switch

This 8-position rotary switch is used to select the SDI Group (G1, G2, G3, or G4) and SDI Subgroups (1, 2 or 3, 4) for the SDI source. The SDI source is selected using the A/B Select switch (Item 4, page 10) on the front of the VPOD LCD display pod.

Audio Level Meters

Audio levels are visually displayed via these two 10-segment, tri-color (RED, AMBER, GREEN) LED bargraph display level meters. The bargraph on the left indicates left channel audio levels of the of the selected source, while the bargraph on the right indicates right channel audio levels. These meters are able to display signal levels using either PPM or VU standards as selected via a DIP switch module accessible by removing the top cover of the unit. See page 25 for specifications and settings of these meters.

Volume Control

This controls the loudness of the audio reproduced by the internal speakers or connected headphone. Clock-wise rotation of this control increases the loudness of the monitored audio in both channels (left and right).

VPOD LCD Video Display Module

Video signals entering the AVMFlex-SA Series unit are monitored through the VPOD LCD video display. The VPOD module is attached to the front panel by a length of flexible gooseneck tubing allowing angle viewing adjustment in all directions. One of five sizes of LCD display screens may be specified, including 4", 5.6", 5.8" (16:9), 6.8", and 7" (16:9) LCD display sizes.

See page 10 for complete information on the use and control of the VPOD LCD video display module.

Balance Control

This adjusts the volume balance between the left and right speakers. See page 18 for a description of the AVMFlex-SA balance control characteristics.
