Installation consists of: (1) unpacking and inspecting the 8200, (2) optional resetting of jumpers for 8200 options (composite output impedance, input termination, input sensitiv- ity), (3) checking the line voltage setting, fuses and power cord, (4) mounting the 8200 in a rack, (5) connect

7、ing inputs, outputs and power, (6) setting the GROUND LIFT switch, (7) optional connecting of remote control leads and (8) optional connecting of computer interface control leads. When you have finished installing the 8200, proceed to “System Setup,” on page 2-41. 1. Unpack and inspect. (includes re

Skip this step if your installation does not need 75 source impedance. The stereo encoder is shipped from the factory with 0 source impedance

14、. This is correct for virtually all installations. However, the 8200 stereo encoder can be changed to 75 source impedance if desired. The frequencies in the stereo baseband are low by comparison to RF or video, and the characteristic impedance of coaxial cable is not 75 at lower frequencies, so the

15、transmission system will have more accurate amplitude and phase response (and thus, better stereo separation) if the cable is driven by a very low source impedance (0) and is terminated with greater than 1k at the exciter. However, a few broadcast organizations require that FM composite be transmitt

16、ed in impedance-matched coaxial cable with 75 source and load impedances.

17、INSTALLATION 2-5 To change the source impedance of one or both of the composite outputs: Make sure that power is off before removing or inserting circuit cards. Remove the stereo encoder board (the second card from the left) from the chassis. To change the source impedance of composite output #1 (th

18、e upper BNC connector on the 8200s rear panel), move jumper JC to the “75” position (Fig 2-3). To change the source impedance of composite output #2 (the lower BNC connector on the 8200s rear panel), move jumper JD to the “75” position (Fig 2-3). Then replace the card and close the chassis. BSet ana

19、log left/right input termination. Skip this step if your installation does not require 600 termination on the analog left/right inputs. The analog left/right inputs are shipped from the factory with balanced bridging (10k) input impedance. However, the 8200 analog inputs can be changed to 600 input

20、impedance. To change the input impedance of the analog left/right inputs: Make sure that power is off before removing or inserting circuit cards. Remove analog I/O board (the first card from the left) and move jumpers JA and JB according to Figure 2-4. Jumper JA sets the right channel and jumper JB

21、sets the left channel.

Skip

22、this step if your installation will supply the 8200 with nominal input level of 10dBu or greater (+5dBu to +27dBu peak). The analog left/right inputs are shipped from the factory with input sensi- tivity to accommodate inputs whose absolute maximum peak level is between +5dBu and +27dBu. If VU meter

23、s are used, +5dBu to +27dBu absolute peak corresponds to a 0VU level of approximately 9dBu to +13dBu. If PPMs are used, +5dBu to +27dBu absolute peak corresponds to a PPM level of approximately 2dBu to +20dBu. However, in unusual circumstances where the input level is very low, the 8200 analog input

24、s can be changed for greater sensitivity.

Fuse F1 must be 3AG Slow-Blow, 12-amp for 115V, or 14-amp (250mA) “T” type for 230V. Fuse F2 must be 3AG Slow-Blow, 4-amp for

34、 115V, or 2-amp (250mA) “T” type for 230V. Power Cord is detachable and is terminated in a “U-ground” plug (USA standard), or CEE7/7 plug (Continental Europe), as appropriate to your 8200s Model Number. Ground Lift Switch can be set to CONNECT (to connect the 8200s circuit ground to its chassis), or

35、 to LIFT (if you are using the 8200s stereo encoder, and are driving its composite output into an unbalanced exciter input). RS-232 and RS-422 Remote Computer Interfaces are provided to connect the 8200 to IBM PC-compatible computers, directly or via modem, for remote control and metering. Both remo

36、te computer interfaces use DB-9 connectors. Remote Control Interface is provided to connect the 8200 to your existing transmitter remote control. The 8200 remote control supports user-programmable selection of up to eight inputs for any one of the following parameters: user presets, factory presets,

37、 test presets, stereo, mono left, mono right, SC1 modulation compensation, SC2 modulation compensation, TX1 overshoot modulation compensation, TX2 overshoot modulation compensation, analog input, digital input, clock reset. The 8200 remote control accepts a DB-25 connector. Two Composite Baseband Ou

The SCA input uses a BNC connector. Digital AES/EBU Input and Output are provided to support two-channel AES/EBU-standard digit

40、R. This is on the rear panel. The 8200 is shipped configured for either 90-130V or 200-250V, 50Hz or 60Hz operation, as indicated on the rear panel. Refer to the units rear panel for your Model Number and the inside of the front cover of this manual for your Model Numbers line voltage setting. To ch

41、ange the operating volt- age, set the VOLTAGE SELECTOR to 115V (for 90-130V) or 230V (for 200-250V) as appropriate. CCheck the value of the fuse and change the fuse if the value is incorrect. For safety, fuse F1 must be Slow-Blow, 12-amp for 115V, or 14-amp (250mA) “T” type for 230V. Fuse F2 must be

42、 Slow-Blow, 4-amp for 115V, or 2-amp “T” type for 230V. DCheck power cord. AC power passes through an IEC-standard mains connector and an RF filter designed to meet the standards of all international safety authorities. The power cord is terminated in a “U-ground” plug (USA standard), or CEE7/7 plug

43、 (Continental Europe), as appropriate to your 8200s Model Number. The green/yellow wire is connected directly to the 8200 chassis. If you need to change the plug to meet your countrys standard and you are qualified to do so, see Figure 2-8. Otherwise, purchase a new mains cord with the correct line

44、plug attached. 5. Set GROUND LIFT switch. The GROUND LIFT switch is located on the rear panel. The GROUND LIFT switch is shipped from the factory set to CONNECT (to connect the 8200s circuit ground to its chassis ground). If you are using the 8200s stereo encoder, and are driving its composite outpu

45、t into an unbalanced exciter input, set the GROUND LIFT switch to LIFT. This will break a ground loop that could otherwise occur. Unbalanced exciter inputs can cause hum and noise because it is difficult to control the system grounding. If hum or noise appears that cannot be cured by resetting the G

46、ROUND LIFT switch, we suggest that you install the optional Orban CIT25 Composite Isolation Transformer at the exciters input to balance it. If you use the CIT25, set the 8200s GROUND LIFT switch to CONNECT. 2-12 INSTALLATION OPTIMOD-FM 8200 6. Mount the 8200 in a rack. The 8200 requires four standa

47、rd rack units (7 inches/17.6 cm). Because the OPTIMOD-FM front panel opens down and out, do not mount your OPTIMOD-FM at the bottom of a rack or above equipment that projects out. There should be a good ground connection between the rack and the 8200 chassis check this with an ohmmeter to verify tha

48、t the resistance is less than 0.5. Mounting the unit over large heat-producing devices (such as a vacuum-tube power amplifier) may shorten component life and is not recommended. Ambient temperature should not exceed 113F/45C when equipment is powered. Equipment life will be extended if the unit is m

49、ounted away from sources of vibration, such as large blowers. The shorter the baseband cable run from OPTIMOD-FM to exciter, the less likely that ground loops or other noise problems will occur in the installation.
