VTA-8060 User Manual (Iss. 01A) Introduction • 1-1

Overview

The Truck Amp is a quick and easy way to alleviate inherent problems that occur naturally when your
mobile unit connects to external feeds. The Truck Amp allows you to control Equalization and Gain
quickly and easily from the convenience of the equipment rack. The Equalization control allows you
to easily set the Truck Amp to compensate for frequency response losses due to the cable length (up to
1000 feet of 8281 or equivalent coax cable) between the mobile unit and the source. The Gain control
has two settings; a ±0.5 dB range for standard feeds, and a ±6 dB range for non-standard feeds. With
a single control, you are assured a flat frequency for a full 10 MHz range. You can solve your feed
problems fast.

The VTA-8060 card is designed for use in the RossGear 8000 series video distribution frames. The
power to each card is individually fused to prevent failure of any one card from affecting the rest of
the cards in the frame. RossGear analog (and digital) cards are also designed to fit into distribution
frames of some other manufacturers for installation flexibility.

The VTA-8060 fills a unique role within the full line of RossGear video distribution products,
engineered to satisfy the highest quality broadcast standards and the most demanding requirements of
your facility.

Features

The Truck Amp provides a heavy-duty solution to the problems that can occur when connecting
external video sources to a mobile studio. Most of these problems are a natural result of the need to
operate in environments which are technically far less than ideal. In addition, the length of video cable
bringing feeds into the mobile varies considerably with each program location

The following features are unique to the VTA-8060 Video Truck Amplifier:

• Remote control of Equalization and Gain from the jackfield location

• Equalization for up to 1000 feet of 8281 coax cable.

• Gain has two ranges; a ±0.5 dB range for standard feeds, and ±6 dB range for

on-standard feed.

• Clamping for minimization of video disturbances

• Easy to Install

Gain Potentiometer Calibration

To calibrate the Gain potentiometer:

1. Ensure that the Gain potentiometer shaft is pushed in.

2. Rotate the potentiometer shaft until it is at roughly half its range

3. Position a knob onto the potentiometer shaft with its indicator pointing at the
"0" on the panel. Press the knob onto the potentiometer shaft until the knob is
fully seated.

4. Using the Allen wrench, turn the knob's set screw to secure the knob to
potentiometer shaft so that it is tight enough to turn the potentiometer and loose
enough to allow the knob to slip turn on the shaft if the knob is turned past the
potentiometer's turning limit. DO NOT TIGHTEN.

5. Measure the resistance of the Gain potentiometer using a digital
ohmmeter. One lead should touch the center gold receptacle; the
other, the outer shielding. See Figure 5.

Figure 6. Measuring Resistance Across the Potentiometer

6. Depending whether the output isles or more than 500 ohms, proceed to step a.
(less) or step b. (more):

a. If the resistance measured is less than 500 ohms, gently turn the knob

counterclockwise until the potentiometer shaft is unable to continue
turning. Continuing turning the knob, you should be able to feel the
knob's hold on the potentiometer shaft "give" and from this point on,
the knob will slip turn on the potentiometer shaft. If you do not feel
the knob slip turning on the potentiometer shaft, loosen the knob's
setscrew with the Allen wrench slightly and try again.

b. If the resistance measured is greater than 500 ohms, gently turn knob

clockwise until the potentiometer shaft is unable to continue turning.
Continue turning the knob, you should be able to feel the knob's hold
on the potentiometer shaft "give" and from this point on, the knob will
slip turn on the potentiometer shaft. If you do not feel the knob slip
turning on the potentiometer shaft, loosen the knob's setscrew with the
Allen wrench slightly and try again.

7. Turn the knob so that it points to "0". If the resistance measured is 500 ohms
(±10 ohms), secure knob to the potentiometer shaft using the Allen wrench
provided and continue to step 5. If the resistance measured is not 500 ohms,
repeat steps 6 and 7.

VTA-8060 User Manual (Iss. 01A) Installation and Setup • 2-5

Equalization Potentiometer Calibration

To calibrate the Equalization potentiometer:

1. Ensure that the Equalization potentiometer shaft is pushed in.

2. Turn the EQUALIZATION potentiometer shaft fully clockwise.

3. Position a knob on the potentiometer shaft with its indicator pointing to just past
the 1000 foot mark on the panel. Press the knob onto the potentiometer shaft
until fully seated.

4. Using the Allen wrench, turn the knob's set screw to secure the knob to the
potentiometer shaft so that it is tight enough to turn the potentiometer and loose
enough to allow the knob to slip turn on the shaft if the knob is turned past the
potentiometer's turning limit. DO NOT TIGHTEN.

5. Rotate the knob fully counterclockwise until the potentiometer reaches its limit.
If the knob is in the proper position it will be pointing to just before the zero
foot mark on the panel. If the knob indicates a distance of zero feet or greater,
gently turn the knob counterclockwise until it points to just before the zero foot
mark. The knob will slip turn on the potentiometer shaft.

6. Rotate the knob fully clockwise until the potentiometer reaches its turning limit.
If the knob is in the proper position, it will be pointing just past the 1000 foot
mark on the panel. If the knob indicates a distance of 1000 feet or less, gently
turn the knob clockwise until it points to just past 1000 feet. The knob will slip
turn on the potentiometer shaft. See Figure 5.

7. Repeat steps 5 and 6 until the distance the knob starts turning BEFORE the zero
foot indicator on the panel is equal to the distance it continues to turn AFTER
the 1000 foot indicator on the panel (in the clockwise direction).

8. Secure knob to shaft using the Allen wrench provided.

9. Repeat steps 1-5 for all additional control module installations.

10. Insert plastic hole plugs (provided with panel) into any vacant holes in the
panel. Do not insert plugs into the holes used to secure the panel to the
equipment rack.

Figure 7. Calibrating the Equalization Potentiometer

Note

As the potentiometer has a larger turning arc than that shown

on the panel, the knob will begin indication before zero feet
and end indication after 1000 feet.

BNC Labels

Affix the supplied BNC label, as per the included instructions, to the BNC area on the rear of the rack
frame.

Cable Connections

The following diagram provides instruction for connecting input and output coax cables to the VTA­8060 when mounted in RossGear 7200 series Video, and 7850 series A/V distribution frames.

It is recommended that all unused outputs be terminated. The specifications in this manual are based
on all outputs being terminated.

1. Connect the external video input to be compensated to the appropriate DA rack
frame BNC looping input connector. Terminate the unused connector.

2. Connect the output cables that you require to BNC outputs 1-6. Be sure to terminate
any unused outputs 1- 4. Do not terminate outputs 5 and 6 if not used.

3. Assemble two coax cables long enough to connect the rack frame to the control
modules. Prepare enough cables for each Truck Amp installation.

4. Connect coax cables to BNC outputs 7 and 8.

5. Run the coax cables to the equipment rack where the Truck Amp panel will be
installed.

6. Connect the coax cable that is connected to the DA rack frame BNC output 8 to the
Gain (upper) BNC output of the module. See Figure 4 and 7.

7. Connect the coax cable that is connected to the DA rack frame BNC output 7 to the
Equalization (lower) BNC output of the module. See Figure 4 and 7.

Board Installation

Use the following steps to install the VTA-8060 cards in a RossGear 7200 series video, or 7850 series
A/V distribution frame:

1. Refer to the User Manual of the RossGear frame to ensure that the frame is properly
installed according to instructions. If this module is to be installed in any compatible
frame other than a Ross Video product, refer to the frame manufacturer’s manual for
specific instructions.

2. Please note that heat and power distribution requirements within a frame may dictate
specific slot placement of cards. Cards with many heat-producing components
should be arranged to avoid areas of excess heat build-up, particularly in frames
using convectional cooling.

3. After selecting the desired frame installation slot, hold the VTA-8060 card by the
edges and carefully align the card edges with the slots in the frame. Then fully insert
the card into the frame until the rear connection plug is properly seated.

VRP-8060 Gain Settings

Fine adjustment of the gain control on the VRP-8060 remote panel should now be made to obtain
proper white levels (as viewed on a waveform monitor). During normal operation, the ±0.5dB range
Gain control will compensate for any small errors that may be present. For non-standard level inputs,
pulling the Gain control increases the Gain potentiometer range to ±6dB. See Figure 9.

Figure 9. VRP-8060 Gain and Equalization Knobs

VRP-8060 Equalization Settings

The following adjustments are made by turning the Equalization control on the VRP-700 remote
panel. See Figure 9.

Cable Length

Adjust the equalization control to reflect the cable length you are using. Remember to include the
entire cable length, both internal and external.

Fine adjustment of the equalization control to achieve the proper chrominance to luminance ratio is
now required. Adjusting the equalization may be accomplished with either a 75% color bar source
signal, or a pulse and bar source signal. If neither are available, the sync and burst may be used.

2-8 • Installation and Setup VTA-8060 User Manual (Iss. 01A)

75% Color Bar

Turn the equalization control so that the top of the color bar’s yellow chrominance is flush with the top
of the white bar.

Pulse and Bar

Turn the equalization control until the bottom of the 12 T pulse is flat.

Sync and Burst

Turn equalization control until the peak-to-peak amplitude of the sync pulse is equal to the peak-to­peak amplitude of the burst.

Once the equalization adjustments have been completed, you will have achieved proper cable
equalization and the frequency response will automatically be flat to 10 MHz without the necessity of
using a sweep signal.

Remote Control by a Voltage Source

In some situations, it may be desirable to control the Truck Amp without using the remote panel. It
has been successfully used in several installations where remote control was provided by a computer
with a digital to analog interface.

To assist in the design of such systems, the following are the approximate ranges of DC control
voltages required as measured on a typical unit.
