Optional Components and Configurations

SECTION 2: INSTALLATION

2.1 USER-INSTALLED OPTIONS

To install options, the top cover of the MRT327 must be removed as shown in Figure 2-1. The following numbered paragraphs are keyed to the numbered items in Figure 2-2.

2.1.1 BALANCED MICROPHONE INPUT

The microphone input is factory configured for use with unbalanced type dynamic microphones. The input can be modified for use with balanced dynamic microphones.

  1. Cut traces W1 and W2 across T1 on the top side of the board.
  2. Install a 600:600 ohm, LM9003 type transformer (RTS part number 2306-0001-05) at T1 on the circuit board.

2.1.2 CARBON MICROPHONE INPUT

This procedure adds a carbon mic headset/handset jack to the back panel of the MRT327.

  1. Install resistors R6 (68 kohm), R7 (820 ohm) and R101 (100 ohm, 1/2 W).
  2. Install capacitors C4 (.033μF/50V mono) and C5 (.1 μF/50V mono).
  3. Install diode D1 (IN6263).
  4. Drill a 3/8-inch diameter hole on the rear panel, and install a Switchcraft number M114B phone jack (RTS part number 2013-0048-00).
  5. Wire phone jack as follows using 24 AWG wire:
    Tip: to E1 on MRT327 board Ring: to E3 on MRT327 board Sleeve: to E2 on MRT327 board

2.1.3 UNSWITCHED MICROPHONE BALANCED (USMB) OUTPUT

This procedure adds an unbalanced microphone output to route the MRT327 microphone signal to external equipment. The output is taken before the microphone on/off switching circuitry.

  1. Install resistor R27 (220 ohm)
  2. Install capacitor C13 (22μF, 50V electrolytic)
  3. Install a 600:600 ohm, LM9003 type transformer (RTS part number 2306-0001-05) at T2 on the circuit board.
  4. Balanced output is obtained at pads E4 and E5 on the circuit board.

2.1.4 HEADPHONE GAIN BOOST

This modification raises the gain of the headphone amplifier from 26 dB to 34 dB for use with headphones that are outside the normal impedance range of 25 to 600 ohms.

  1. Install R42 (1.2 kohm)
  2. Install C30 (10 μF, 25V electrolytic).

2.1.5 LOCAL POWERING OPTION

This modification lets you use a separate power source to power the MRT327. This procedure can be used, for example, to power the MRT327 when wire resistance for long cable runs reduces the supply voltage from the intercom system below a usable level.

Use a dc power supply with a minimum output of +14 Vdc at 500 mA. Connect the positive side to pad E10. Connect negative side to either pad E11 or E12.

2.2 SPEAKER MUTING TRIMMER ADJUSTMENT

The speaker muting trimmer is accessible with the top cover removed. This trimmer adjusts the amount of speaker muting (also called speaker DIM) when the microphone is activated. Normally some amount of muting is required to prevent feedback between the microphone and speaker. Muting is factory preset at -6 dB. Turn trimmer R32 counterclockwise to increase speaker muting.

Note

If the MRT327 is always used as a speaker station and is not used with headphones, it may be possible to stop feedback using the Sidetone trimmer (accessible through the front panel) instead of removing the top cover and readjusting the speaker muting trimmer.

2.4.2 EXTERNAL SPEAKER, J27

The SPEAKER OUTPUT jack provides an output for an external speaker (8 ohms minimum). The external speaker is connected using a 1/4-inch phone plug as follows;

Tip: Speaker high

Ring: Speaker low

Sleeve: No connection

2.4.3 HEADSET

Headphones should be 25-600 ohms. Lower impedance headphones are not recommended. Headphones with good acoustic isolation (20 to 40 dB) improve communication in high-noise environments and allow the user to listen at a less tiring, lower volume. The headset jack is wired as follows:

Pin 1: Balanced mic* low/unbalanced mic common

Pin 2: Balanced*/unbalanced mic high

Pin 3: Headphone/mic switch common

Pin 4: Headphone high

Pin 5: Headphone high

Pin 6: Mic switch high

*Balanced mic optional, see paragraph 2.1.1.

  1. Tap the CHANNEL 1-2 button to select the desired channel.

  2. Tap the PANEL MIC button once to select the optional panel mic jack (button in); tap it again to select the dynamic mic headset jack (button out).

  3. The MIC ON button has two modes of operation:

a For push-to-talk operation, press and hold the button while talking. When you release the button the microphone will shut off.
b. For hands-free talk, tap the button once to turn on the microphone. Tap the button again to turn off the microphone.

The mic LED indicator lights when the mic is on.

  1. Tap the SPKR ON button once to activate the optional external speaker (button in). Tap it again to turn the speaker off (button out).
  2. Adjust the headphone / speaker listening level using the VOLUME control.
  3. The Sidetone trimmer may be used in either of two ways:

a. When using a headset, the Sidetone trimmer may be used to adjust the level of the user's own voice in the headphones. While speaking into the microphone, adjust the trimmer for the desired voice level.
b. When using an external speaker and a panel microphone instead of headset, the Sidetone trimmer may be used to minimize feedback between the speaker and the microphone. While talking into the microphone, adjust the trimmer to minimize the speaker output.

  1. To send a call signal, select the channel to be called, then press and hold the CALL button. The call LED will light while the button is pressed. When the called station responds, release the CALL button.

The call LED will flash when there is an incoming call signal on the currently selected channel. To respond, activate the microphone and begin talking.
