For 100V installations, speakers can be arranged into two suitable circuits. Each zone is enabled using its front-panel selection switch, making it convenient to operate one area or both. The amplifier's 380W output is shared across the speaker system. The required speaker quantity and transformer taps should be chosen according to the installation's coverage and power needs. Useful Commercial Installations Professional & Public Offices Manage audio between customer-facing spaces and staff common areas, with compatible microphone paging. Community & Training Facilities Distribute shared programme audio between two speaker circuits serving halls, meeting rooms or activity areas. Commercial Showrooms Provide background music in a main display area and selectively enable a secondary customer space. Recreation & Service Buildings Connect suitable commercial speakers across primary and secondary operating areas. Zone Control Clarification: The PA380 allows Zone 1 and Zone 2 to be switched independently. Both active zones receive the same audio programme. The amplifier does not provide two independent music sources or separate built-in zone volume adjustments. Organize Music and Paging Sources The integrated media player offers Bluetooth, FM, USB and SD operation. Compatible MP3 and WMA files can be used with supported removable media. For a permanent business music source, AUX1 or AUX2 can be connected to suitable external equipment such as a dedicated music player or media streamer. Individual controls for microphones, auxiliary sources and the media player allow audio input levels to be adjusted before setting the overall master volume. Paging Priority from MIC1 The rear panel MIC1 priority switch provides an ON/OFF selection for voice-priority ducking. When the feature is enabled, an announcement made using MIC1 can lower the level of background music so spoken messages remain more prominent. This is useful for day-to-day announcements in facilities where music and paging share the same speaker system. Professional Microphone Connections MIC1 and MIC2 provide convenient front-panel ¼-inch connections. MIC3 and MIC4 are available through rear-panel combination XLR / ¼-inch inputs. The amplifier includes a 48V phantom power switch for compatible microphones connected to the supported rear inputs. Microphone Setup: Check whether a microphone requires phantom power before enabling the 48V setting. Incorrect microphone power configuration may cause equipment problems. External Audio Equipment The REC and LINE connections provide additional ways to integrate the PA380 with compatible external equipment. The LINE output can be connected to a suitable power amplifier or active subwoofer, subject to the equipment's line-level input requirements.

Chime and Siren Functions Dedicated front-panel switches provide access to the PA380's built-in chime and siren audio functions. These functions offer additional audio options for suitable general-purpose paging and announcement applications. Safety Information: The built in siren does not indicate certification as a fire alarm or regulated emergency voice evacuation system. Adjusting Speech Clarity Use the microphone input volume controls to establish appropriate paging levels. Bass and treble adjustments can help balance the overall system sound, while the microphone echo control can be adjusted for appropriate voice applications. For routine paging, use echo sparingly to preserve speech intelligibility. Media and Source Balance The PA380 provides separate microphone, auxiliary and media player controls. These help balance connected sources so that switching between music and announcements does not create excessive volume differences.

Do not operate the two zone 100V speaker configuration and low impedance configuration at the same time. How the Two Speaker Zones Work The PA380 provides separate selection switches for two 100V speaker circuits. These switches determine which connected areas receive the amplifier's music and paging programme. Zone 1 — Primary Circuit An example could be a main shared room, sales area or multipurpose space. Zone 2 — Secondary Circuit An example could be a reception area, corridor, supporting room or another speaker section. Operating Choices Zone 1 Only Enable the first speaker circuit while Zone 2 remains inactive. Zone 2 Only Enable the second speaker circuit while Zone 1 remains inactive. Both Zones Enable both speaker circuits to receive the shared programme. Shared Amplifier Capacity Both speaker circuits operate within the combined 380W rating. Important: The two zones share the same audio sources. The PA380 does not provide two independently routed music programmes or individual built-in zone volume controls. Need Different Listening Levels? Compatible commercial 100V wall volume controls may be considered when each area requires local level adjustment. The selected volume controls must be properly rated for the connected speakers, and the complete amplifier load must be considered. Speaker Output Configurations Two Selectable 100V Zones For two separately switched commercial speaker circuits. Direct 100V Output An alternative output terminal option for compatible commercial speaker system wiring. 4–16Ω Speaker Output For suitable low-impedance speaker configurations. Match the System Choose a compatible output method before connecting speakers. Speaker Connection Warning: Do not use the two-zone 100V speaker connection and the low-impedance speaker connection at the same time. Switch off the amplifier before changing speaker connections or output wiring. 380W Power & 100V Speaker Load Planning For distributed 100V audio, the combined speaker load is calculated by adding the selected transformer wattage taps of every connected speaker. The PA380 is rated at 380W total output, shared across its speaker circuits. A conservative starting point is to reserve 20% of amplifier power rather than design the system at its full rated output. 380W Rated amplifier output 304W Conservative planning load 76W 20% planning reserve Power Planning Note: The 304W connected-load target uses a conservative 20% headroom allowance. This is a system design recommendation, not a separate manufacturer power rating. Example Two-Zone Installation The following is an illustrative 100V speaker configuration using commercial speakers with 10W transformer taps. Speaker Circuit Speakers Tap Each Load Zone 1 10 10W 100W Zone 2 8 10W 80W Combined 18 10W 180W The combined 180W load leaves 200W of unused rated amplifier capacity. This is a tap-loading calculation only. Confirm the permissible loading of each zone against the output requirements of the particular installation. The manual does not publish a separate per-zone wattage rating.

Actual speaker placement, tap selection and count depend on room size, ceiling height, ambient noise and desired level. How Are 100V Speakers Connected? Compatible transformer-equipped 100V speakers are normally connected electrically in parallel. Maintain the correct polarity throughout each speaker circuit and verify the transformer tap settings before applying amplifier power. Can I Connect Regular 8Ω Speakers? Yes. The PA380 includes a separate 4–16Ω output for suitable low-impedance speaker systems. Calculate the combined speaker impedance before connecting multiple speakers. Low-impedance compatibility must not be determined using 100V transformer tap calculations. Can I Extend the Audio System? The LINE output can feed suitable external line-level audio equipment, including a compatible additional power amplifier or active subwoofer. This connection is an audio signal output, not another powered speaker terminal. Installation & Initial System Checks Correct input configuration, speaker-output selection and loading are important for stable operation. Before Powering On Disconnect the amplifier from AC power before working on speaker wiring. Choose the appropriate 100V or low-impedance speaker output configuration. Confirm transformer speaker tap settings for each 100V circuit. Calculate the combined speaker load for the complete system. Check terminal polarity and inspect for exposed wire or short circuits. Connect compatible microphones and external audio sources. Enable 48V phantom power only where appropriate. Set the microphone, AUX, media and master levels low before initial testing. Keep the amplifier ventilation openings unobstructed. Testing Each Zone Start with a compatible audio source selected. Enable Zone 1, gradually raise the relevant input level and master volume, and confirm normal sound. Repeat the procedure for Zone 2, then test both speaker circuits together. Testing Paging Priority Connect a suitable microphone to MIC1 and enable the rear-panel voice-priority switch. Play background music and make a short announcement. Confirm that the background music level is reduced during paging. Checking External Audio Connections Confirm that connected equipment uses an appropriate line-level input or output. Do not connect powered speaker terminals to AUX, REC or LINE signal connections. Installation Reminder: Incorrect speaker output selection, excessive load or shorted wiring may damage connected equipment. Always follow the manual and applicable electrical installation requirements. Commercial Music: Public playback of music in Canadian business premises may require appropriate music licensing. Check the requirements for the intended use.
