Outputs - Ecler eHMA Série Notice D'utilisation

The Talkover (priority) function operates when a signal is detected at the inputs 1 to 3 this
function is assigned to; it attenuates the other inputs of the unit that don't have priority. Turn it on/off for
each input channel with the "TK" switch on the front panel.
With the CHIME function, closing a dry contact connected to CHIME terminals on the rear panel
triggers a chime ("ding-dong"), usually to announce a voice message sent from a microphone or a paging
station. With the adjacent VOL control, you can adjust its volume. This function is available on eHMA120
and eHMA240 models.
•
To manage the important level differences existing between conventional CD and LINE sources
and other devices capable of producing audio signals, the LINE inputs (and the MIC/LINE inputs in
LINE mode)of the eHMA are standard line inputs (0dBV) with a ±15dB gain control for low-level
sound sources such as media players, portable MP3 players, tablets, computers, mobile phones,
etc.
Turntables CAN NOT be directly connected to this unit, because it has no RIAA preamp equipped
input.

5. OUTPUTS

The eHMA offers the following powered outputs:
• 1 low impedance (4Ω) mono output: all models
•
1 mono 70/100V line (high impedance) output: eHMA60
•
2 mono 70/100V line (high impedance) zone outputs (Z1 and Z2), with switches on the front panel
to enable or disable the speaker line connected to each of them): eHMA120
•
4 mono 70/100V line (high impedance) zone outputs (Z1 to Z4 + ALL), with switches on the front
panel to enable or disable the speaker line connected to each of them): eHMA240
Outputs should be used as follows:
•
Low impedance output (4Ω), for a speaker or set of speakers with an overall impedance
equivalent to 4Ω. In this case, use the LOW- Z OUT (+ and -) terminals of the OUTPUT
section on the rear panel
•
High impedance outputs, 70V or 100V, for a (large) set of speakers equipped with 70V or
100V line transformers, and whose total power required is not greater than the nominal
power supplied by the eHMA model. In this case, use the 0V and 70V or 0V and 100V
terminals of the OUTPUT section on the rear panel
The master output level of the unit (OUTPUT VOL) must be adjusted so that SP (Signal Present)
indicator indicates activity and overload (CLIP) is not permanently lit, but at most blinks to the rhythm of the
low frequencies.
Other connections on the back panel:
•
AUX/REC output (not available for eHMA60) with a nominal output of 0dBV (10kΩ load).
•
MUTE remote control input: to connect an external dry contact closure. It allows connection of fire
detection systems and other safety devices that have to mute the mixer by using this control signal.
The mode of operation is "NO" (normally open).
