Two zones from one amplifier

ZONE 1 and ZONE 2 high impedance outputs each carry a 70 V or 100 V loudspeaker line, switched on or off from the front panel, while LOW-Z OUT serves 4 Ω loudspeakers.

Paging with chime

Closing a dry contact on CHIME TRIGGER plays a chime before a message from a microphone or a paging station, with its own volume control; talkover lowers the music by 30 dB.

Backup power

The mixer runs from its 24 V DC power supply and has a separate 24 V DC battery input for backup systems.

In the box

• 1 x eHMA120 powered mixer
• 1 x 24 V DC external power supply
• 1 x rack mount kit

Workflow 1: Shop background music with announcements

Retail stores with ceiling loudspeakers.

Connections

Setup

1. Connect the 100 V loudspeaker line to 0 V and 100 V.
2. Set the microphone input GAIN.
3. Switch on TK for the microphone input.
4. Set OUTPUT VOL so CLIP only blinks on the low frequencies.

Tip: Talkover lowers the music by 30 dB during announcements.

Workflow 2: Restaurant and bar

Dining areas with background music and a host microphone.

Connections

Setup

1. Connect the loudspeakers to the matching output.
2. Set the bass and treble with a screwdriver.
3. Set channel VOL high and OUTPUT VOL to the room level.

Tip: Screwdriver tone controls keep staff from changing the sound by accident.

Workflow 3: Fire alarm muting

Installations that must fall silent on an alarm.

Connections

Setup

1. Wire the normally open contact to MUTE.
2. Trigger a test alarm.
3. Check that the MUTE LED lights.

Tip: The MUTE input works with a normally open dry contact.

Workflow 4: Low impedance loudspeakers

Small rooms with a few 4 Ω loudspeakers.

Connections

Setup

1. Match the total load to 4 Ω.
2. Connect with correct polarity.
3. Set the output level.

Tip: Do not use the high and low impedance outputs at the same time.

Workflow 5: Two-zone shop with chime paging

Sites that switch loudspeaker lines on and off by area.

Connections

Setup

1. Connect each area to its own zone output.
2. Use the front ZONE switches to turn areas on or off.
3. Set OUTPUT VOL for the whole system.

Tip: Total power of all zones must not exceed the rated output.

Workflow 6: Energy saving

Venues where the system is often idle.

Connections

Setup

1. Press the AUTO switch.
2. With no input signal the unit enters standby.
3. It returns to normal operation as soon as a signal appears.

Tip: Standby consumption is only a few watts.
