This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.

Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

The manual was properly scanned and perfectly readable. The only small problem is that I couldn't use my dear Ctrl + F to find a word I needed.

Nothing wrong with the manual or the delivery - came to me the same day I ordered it. But afterwards I realized that I ordered the wrong manual. Probably better with the Quick start - version. So maybe it would be better if we could see a list with inhold for each manual before ordering?

Bought T4850 High End Tuner a few years ago, but i didn't know where all the buttons were used for. So i purchased the owners manual. Perfect! Just what i needed.
Model 450 Series II User Guide
WIRING CONNECTIONS
Refer to Figure 1 and Table 1 below. For unbalanced operation, the GREEN wire is connected to the audio input, the WHITE wire is connected to the audio ground, and the SHIELD is connected to chassis ground. In some cases, audio ground and chassis ground will be the same. For balanced operation, the GREEN wire is connected to the positive audio input, the WHITE wire is connected to the negative audio input, and the SHIELD is connected to chassis ground.

SHURE MODEL 450 SERIES II PAGING AND DISPATCHING MICROPHONE
The Shure Model 450 Series II is a high output dynamic microphone designed for paging and dispatching applications. This extremely rugged microphone features an omnidirectional pickup pattern and a frequency response tailored for optimum speech intelligibility. It also includes an impedance selection switch and a locking press-to-talk switch. The press-to-talk switch can be converted to a monitor/transmit switch with the Shure RK199S Split-Bar Conversion Kit.

PRESS-TO-TALK SWITCH OPERATION
To operate the control bar as a press�to�talk switch, simply hold it down and begin speaking. When you are finished speaking, release the control bar. To lock the control bar in the �on� position, press it down and pull it forward. To unlock the control bar, push it back and release it.
NOTE: The RED and BLACK leads are not part of the audio circuit. These wires provide a contact closure when the pressto-talk switch is depressed. This closure may be used to control an external relay or a transmit/receive circuit.
CHANGING PTT CIRCUIT TO NORMALLY OPEN
IMPEDANCE SELECTION
To select high or low impedance, move the impedance selection switch, located under the microphone base, to either the HIGH or LO position. The switch is factory pre�set to LO. Shure recommends the low impedance setting if long lengths of cable are used, or if severe hum is encountered. Use Shure A95 Line Matching Transformers to match a low impedance (300 �) microphone line to a high impedance amplifier input.
Using microphones in parallel requires a normally open microphone circuit. To modify the press�to�talk switch so that it provides a normally open circuit, proceed as follows: 1. Remove the screws, washers, and bottom plate from the microphone. 2. Unsolder the black, red, and white leads from the terminal of the press�to�talk switch (see Figure 1). Make sure these leads are still soldered together. If necessary, resolder them and insulate the connection. 3. Replace the bottom plate and secure it with the screws and washers removed in Step 1.
