1. IMPORTANT NOTE

We thank you for choosing our HMA180 powered mixer with high and low output impedance (70V / 100V line). To achieve the optimum operation and performance of this unit, it is VERY IMPORTANT before you plug anything in - that you carefully read this manual and closely follow all its indications. To guarantee optimum operation from this unit, we strongly recommend that its maintenance be carried out by our Authorised Technical Services.

1.1. Precautions

This device must be grounded through its power cord. Any change in the configuration of the unit must be implemented by a qualified technician. Before any work is done on the unit, disconnect it from the power source.

2. INTRODUCTION

HMA180 is a professional 2-rack powered mixer, with 9 input audio channels and a wide range of additional functions for managing priorities between inputs, sending pre-recorded voice messages for emergency and evacuation situations, etc. HMA180 is a compact professional sound solution where the end user is not necessarily an expert in using audio equipment, as it offers simple start-up and use.

Its main features are as follows:

 3 balanced and mixable microphone inputs  1 input for the message console with priority over all other audio sources (PAGER) and chime

melody (CHIME)

 4 line inputs for music sources (background music), with one of the dials on the front panel  Independent level controls for mixing PAGER, MIC1, MIC2 and MIC3 signals on the front panel  3-band equalizer for mixing PAGER signals and microphones  3-band equalizer for selected music source  Additional EMERGENCY MIC/LINE input with maximum priority (for emergency or evacuation

messages), with 3-band equalizer and playback volume control independent of all other signals

 24VDC output for managing external priority relays, linkable to the PAGE and/or EMERGENCY

functions

 Remote volume control through WPm (0 - 10VDC) series wall panels  MUTE control input to silence the unit from an external device through dry contact closure  PAGE and EMERGENCY control inputs to activate the PAGER and EMERGENCY functions

through external dry contact closure

 Auxiliary output  Insertion point  Mono amplifier output, low (8 ) and high (70V / 100V) impedance

3. INSTALLATION

HMA180 is a self-powered mixer especially designed for its installation in 19" rack cabinets or on desktops, occupying two units of space. You need to bear in mind two points when positioning your HMA180 unit: maximum ease-of-use and allowing easy access for input and output connections. The unit must be placed away from noise sources (dimmers, motors, etc.) and network cables. A 4A timed network fuse is built-in to protect the unit against overloads. If it blows, it will be replaced with another fuse of identical characteristics. IN NO CASE MUST A HIGHER VALUE FUSE BE INSTALLED.

CAUTION: Only qualified technical personnel may replace fuses.

4. AUDIO INPUTS

The HMA180 supports two types of signals on its input channels:

 Microphones: they have a Euroblock, jack or XLR balanced connection, which can support

a level of -20dBV to –50dBV, adjusting sensitivity through the ADJ control on the rear panel

The microphone inputs have Phantom power to power condenser microphones, activated by the jumper (see 10. CONFIGURATION DIAGRAM section).

 Line signals: they have an unbalanced RCA double jack or minijack stereo connection.

They can support signals ranging from 0dBV to -15dBV, adjusting sensitivity through the ADJ control on the rear panel. You can connect the signals of CD players, radio tuners, mixing consoles, media players, the audio outputs of PCs and tablets, etc. to these connections.

NOTE: Turntables CANNOT BE CONNECTED directly to this device because none of the inputs have an RIAA preamp.

4.1. MIC1, MIC2, MIC3 inputs

These 3 microphone inputs can work simultaneously, so they can be mixed through their LEVEL controls on the front panel and equalize the resulting mix with the TONE CONTROL, also on the front panel, in the MICROPHONES section. The microphone mix playback volume (+ music source selected, if any) will depend on the OUTPUT VOLUME of the unit.

4.2. PAGER input

This input is especially designed for connecting a microphone voice announcements console in real-time, MPAGE1 or similar. This signal's input is injected into the device and it attenuates or mutes the rest of the sound content sent to the device's output (music source selected + microphones), taking its place and allowing the broadcast of the voice message with the desired clarity. The playback volume of the message depends on the adjustment of the PAGER LEVEL control on the front panel, with this being independent of the device's OUTPUT VOLUME, but on which the listening of the rest of the signals depends (music source selected + microphones). However, the TONE CONTROL of the MICROPHONES section also acts on the PAGER input. The PAGER function can be triggered by automatic detection of the incoming audio signal level or a change of status of an external contact connected to the PAGE control port in the CONTROL INPUTS section. Refer to the 10. CONFIGURATION DIAGRAM section for more information on the configuration options of this function using jumpers. After activating the PAGER function, the CHIME micro-switches allow the initial playback of a chime melody (“ding-dong”) from three options, when one or both of the micro-switches is in the ON position. The VOL control next to it allows you to adjust the volume of the melody, before the voice message is played.

4.3. MUSIC inputs

These 4 inputs for music sources cannot work simultaneously. You need to select with the SOURCE control on the front panel which of them you want to listen to on the unit's output (1, 2, 3, 4 or none of them). They are mixed through its LEVEL control with microphones 1/2/3, if available. The TONE CONTROL in the MUSIC section acts on the MUSIC input selected. The volume that the mix between the music source selected and microphones 1/2/3 connected will be played at will ultimately depend on the OUTPUT VOLUME of the unit.

4.4. EMERGENCY input

This input has been designed to connect a microphone or a pre-recorded file playback system that will broadcast an announcement or emergency and/or evacuation message on a slot with maximum priority. Therefore, this input has a series of special features:

 It supports balanced microphone signals  It supports balanced line signals (occasionally the distance between the message

playback device and the HMA180 might be high, with a connection of this type ideal for minimising the effects of noise and interference induced along the wiring between both devices)

 It has a tone control totally independent of the rest of the device's tone controls  It has a VOL playback volume control totally independent of the rest of the device's

volume controls

 It has maximum priority: during its operation, it mutes any other sound source selected for

playback, including those of the PAGER, MICROPHONES and MUSIC inputs

The EMERGENCY function can be triggered by automatic detection of the incoming audio signal level or a change of status of an external contact connected to the EMERG control port in the CONTROL INPUTS section. Refer to the 10. CONFIGURATION DIAGRAM section for more information on the configuration options of this function using jumpers.

The EMERGENCY audio input is doubly labelled as MIC4 / LINE5. This is because, if the EMERGENCY function is not required in an installation, the audio signal connected to this input could be used as an additional line or microphone input on the device (without taking priority over the others). Refer to the 10. CONFIGURATION DIAGRAM section for more information on the configuration options of this function using jumpers.

4.5. INSERT input

The ¼” INSERT stereo jack serves as an insertion point for the use of dynamic processors or external effects to be inserted in the device's general mixing bus. A standard cable will be used in these types of connections: The send signal is found on the tip of the jack and the return on the ring, with both signals having the same grounding

5. OUTPUTS

The HMA180 has a dual amplified output:

 Low impedance (8 ), for the connection of a speaker or set of speakers with an overall

impedance of 8 . In this case, use the 8 pin connector  (+ and -) of the SPEAKER OUTPUT section on the rear panel

 High impedance, 70V or 100V, for the connection of a large number of speakers with

transformers/adapters for 70V or 100V, and whose total required power is not more than the normal power supplied by the HMA180. In this case, use 0V and 70V terminals or 0V and 100V on the SPEAKER OUTPUT of the rear panel

The AUX OUT auxiliary output provides a mono signal at line level (0dBV), which replicates the unamplified signal delivered to the SPEAKER OUTPUT terminals. Therefore, it is possible to use that output to connect the HMA180 to one or more additional amplifiers that can serve areas with higher power requirements.

The HMA180 also has a high pass filter with a cut-off frequency at 70Hz, ideal for optimising audio performance in high impedance installations. Refer to the 10. CONFIGURATION DIAGRAM section for more information on the configuration options of this function using jumpers.

6. REMOTE CONTROL PORTS

The HMA180 has a series of control inputs and outputs on its rear panel for the integration with other devices in an installation:

 REM VOL (REMOTE VOLUME): enables the connection of a WPm series or WPTOUCH wall

control panel for remotely managing the device's output volume (mix of microphones + music source) through a voltage of 0 – 10VDC (*). When the LOCAL / REMOTE dial is in the LOCAL position, the volume is controlled by the OUTPUT VOLUME on the front panel. In the REMOTE position, the volume is controlled by the device connected to the REM VOL port

 CONTROL INPUTS: activation of different functions by means of using external dry contacts. They

can either act in NO (normally open) or NC (normally closed) mode. Refer to the 10. CONFIGURATION DIAGRAM section for more information on the configuration options of this function using jumpers:

o PAGE: activation of the PAGE function for sending messages from an MPAGE1 type

announcement microphone or similar connected to the PAGER input

o EMERG: activation of the EMERGENCY function for sending messages from an

announcement microphone or pre-recorded message player connected to the EMERGENCY input

o MUTE: mute activation of the whole device

(*) NOTE potentiometer, which means all of the grounding points must be joined. The connection cables can be up to 500 m in length with a cross-section of 0.5 mm

: a maximum of 16 ports may be connected in parallel to the same control

or more.

7. CONSIDERATIONS

7.1. Switching on the unit

This is done directly by using the front ON / OFF switch. In a full audio installation it is essential to start up the equipment in the following sequence: sound sources, mixer, equalizers, processors and, finally, power amplifiers. To shut these down, follow the reverse sequence.

7.2. Gain adjustments, levels and indicators

Adjust the input gain level on each signal by using the ADJ control on the rear panel. Next, adjust the mix volume between the input channels using their respective LEVEL controls on the front panel, and the overall output volume using the VOLUME control on the OUTPUT section. The -40dB indicator will light up when the signals are sufficiently strong to be considered as audible, lighting up with greater intensity when their level increases. The CLIP indicator will begin to light up if the mix is high enough to be close to the device's saturation point. It is normal that when operating at high output power, the CLIP indicators light up in synchronisation with the bass frequencies, which carry the most energy. Make sure that these indicators do not remain permanently lit.

7.3. Equalization

The TONE CONTROL of the different inputs provides a gain / attenuation of ±15dB for each of the following bands:

 BASS: 100Hz ±15dB  MID: 1.8kHz ±15dB  TREBLE: 10kHz ±15dB

Given the device's philosophy of use, it includes a tone control system that requires adjustment with a screwdriver, thus preventing the manipulation of it accidentally during the normal use of the unit.

7.4. Ground loops, background noise

You must make sure at all times that the signal sources connected to the unit do not have interconnected grounds, i.e. that the grounding never reaches them through two or more different paths, as this can produce humming which may interfere with the quality of the audio production. The cable shielding, being connected to the chassis, must never be interlinked to avoid the formation of ground loops.

7.5. Cleaning

The front panel should not be cleaned with solvents or abrasive substances because the silk printing could be damaged. To clean it, use a slightly damp soft cloth, dampened with water and neutral liquid soap; dry it with a clean cloth. Make sure that water never gets into the amplifier through the holes on the front panel.
