SECTION 1: INTRODUCTION The TRI-PAK™ TR-230 is a high quality, two channel digital audio system delivering any combination of music, paging, and sound masking applications – either as two separate zones or as a single 2-channel zone – into commercial buildings. The DSP-based unit delivers two 30 watt channels to selectable outputs at 25 volt, 70 volt, or 100 volt. Two uncorrelated, on-board digital noise generators provide masking signals at either -4 dB per octave or NC40 via switch selection.

SECTION 5A: QUICK START APPLICATION GUIDE 5A. QUICK START 5A.1. SOUND MASKING ONLY Step 1: Turn down masking volume controls on front panel full counter clockwise with small flathead screwdriver. Step 2: Make following DIP switch selections on SW4, SW5 and SW6 on rear panel: • Select “masking on” by putting DIP switch 1 up in SW4 and SW5. • Select a noise type (–4dB or NC40) on position 1 of SW6. • Select appropriate speaker type on positions 5 and 6 of SW4 and SW5 (P-25, E-5, or flat).
SECTION 5A: QUICK START APPLICATION GUIDE 5A.3. MUSIC ONLY Step 1: Turn down music volume controls on front panel full counter clockwise. Step 2: Make following DIP switch selection on SW4, SW5 and SW6 on rear panel: • Select appropriate speaker type on positions 5 and 6 of SW4 and SW5. Step 3: Connect music source to Music/Line inputs connectors on J7 and J10. Wire as follows: Shield to -, Positive to + terminals. NOTE: The TR-230 automatically sums Stereo input, to Mono for each channel.
SECTION 5B: SOUND MASKING APPLICATION GUIDE The TR-230 provides Sound Masking via two uncorrelated built-in noise generators and includes a choice of two pre-filtered noise signals – the industry recognized NC40 or a - 4 dB per octave spectra. Additionally, both speaker response EQs and space effect EQs are provided to simplify the process of achieving speech privacy with a non-intrusive masking sound of good tonal quality. 5B.1.
SECTION 5B: SOUND MASKING APPLICATION GUIDE 5B.2. FACTORY DEFAULT SETTINGS The factory default settings for sound masking are the same for both speaker outputs, which are labeled Zone 1 and Zone 2 on page 5. These default settings (as listed in page 6 for SW4, SW5, and SW6) are as follows: • Masking sound OFF • No speaker EQ • Normal space EQ • - 4 dB per octave noise pre-filter 5B.3.
SECTION 5B: SOUND MASKING APPLICATION GUIDE 5B.4. CLOSED PLAN SET-UP PROCEDURE For a closed plan application, it is usually recommended to use a single masking signal in a single architectural zone with the P-25 model i-ceilings speaker installed (one to a room for rooms up to 20' x 20'). NOTE: For larger rooms, where four or more P-25 speakers may be needed, it may be appropriate to use a 2 channel, 1 zone layout instead.
SECTION 5C: PAGING APPLICATION GUIDE The TR-230 provides two independent 30 watt zone outputs for voice paging. Paging is accomplished using telephone and/or microphone sources with the following options: • • • • Single zone or All-Call paging Duck or mute music during page Hands-free talkback DTMF decoding for zone page access Paging can be provided over both music and masking.
SECTION 5C: PAGING APPLICATION GUIDE For a 5 second timeout, put position 2 switch in the ON mode. For a 10 second timeout, put position 2 switch in the OFF mode. NOTE: The factory default setting is 10 seconds. If you are experiencing any problems getting locked out by a PBX system, try using the 10 second timeout. Make speaker line connections to the Zone 1 and/or 2 output connection blocks (J12 and J14). Ensure all speaker conductors are secure and speaker tap settings are correct.

SECTION 5C: PAGING APPLICATION GUIDE 5C.2. PAGE EXPANSION TELEPHONE SYSTEM PAGING TO A SECOND TR-230 OR ADDITIONAL AMPLIFIER(S) The TR-230 has one balanced line output per zone. Connect each balanced line output to the corresponding input of the secondary TR-230 or amplifier. This will allow each zone page to pass from the primary to the secondary device(s).
SECTION 5C: PAGING APPLICATION GUIDE 5C.3. PAGING VIA MICROPHONE The TR-230 requires a line level pre-amplified microphone providing a nominal 0 dBu output and contact closure (normally open). Any microphone should work if used in conjunction with an external mic pre-amp that provides the nominal 0 dBu output. Microphones with built-in DTMF output can be connected to the J3 input connector (see Figure 10).

SECTION 5C: PAGING APPLICATION GUIDE 5C.4. PAGING WITH TALKBACK The TR-230 talkback function provides a “hands free” intercom wherein the designated loudspeaker provides paging and music but also enables the speaker to function as a microphone. This function is activated in SW4 (Zone 2) and SW5 (Zone 1) as follows: To enable talkback, turn switch positions 7 and 8 of either SW4 or SW5 UP to the “ON” position (this will enable talkback and mute music during a page).
SECTION 5D: MUSIC APPLICATION GUIDE The TR-230 allows multiple music sources to be used for background or foreground music. Music can be muted or ducked in either channel during a page through the proper selection of switch options. Primary MUSIC inputs are made via the J7 (Zone 2) or J9 (Zone 1) rear panel connectors using 5-pin terminal block connectors. Music inputs automatically sum the right and left channels of a stereo source providing a mono output per zone.
