Preliminary operaons

Package list

The box contains the following:

1 Mezzo amplier

Block connectors 4 rubber feet 2 Bracket A 2 Bracket B

6 screws (for aaching the brackets)

Mains power cable

Locaon

Install your amplier in locaon that allows some exchange of air. Amplier comes with mounng accessories for the following mounng opons Surface mount – Using 2 “bracket B” it’s possible to mount an amplier vercally on a wall or upside down under a table or in a

ceiling.

Tandem 19” rack mount – Using the 2 “bracket B” it’s possible to

mount two Mezzo side to side and then mount them using the 2

“bracket A” in 1 RU in a 19” rack. Single 19” rack mount – Using the 2 “bracket A” it’s possible to mount a single amplier in a 19” rack. Single half rack mount – Using the 2 “bracket A” it’s possible to mount a single amplier in a half width rack. On a shelf – Aach the rubber feet to the boom of the amplier

and place it on the desired surface. Plenum mount – 320 W models are approved for placement in air handling spaces above the ceiling if the mains cable is mounted inside the plenum mount accessory (sold separately).

Custom mount – It’s possible to custom design ngs for poles and other applicaons using screws ng the threaded holes in the amplier. These screws must not be longer than XX mm. The safest

way to avoid mistakes is to use the provided screws.

Cooling

The 600W models implement a temperature controlled forced-air cooling system. Air enters from the front and exists at the back of

the amplier. The fan has 3 modes: STILL - if the temperature of the space surrounding the amplier is ≤35C and the average power out is ≤1 W per channel. (≤84 dB SPL*) WHISPER - if the average output is ≤4 W per channel. The fan noise at 1 m is ≤30 dBA in this mode. (≤90 dB SPL*)

REGULATED - Mezzo adapts the speed of the fan to stay cool. The

fan noise at 1 m is ≤45 dBA in this mode. (≤105 dB SPL* depending

on model and power sharing)

In the rare event of overheang the amplier will mute all channels and run the fans to reach a safe temperature and start operang

again.

It’s ok to stack ampliers on top of each other in a rack, but it’s

recommended to put them in banks of 4 RU and then leave a 1 RU space.

*(SPL at 2 m with 90 dB1W1m sensivity)

This amplier does not have a power switch. It will turn on automacally when AC power is connected and it will go to standby mode if no signal is present for 25 minutes. When input signal exceeding -60 dB relave the level needed for full power is applied the amplier will go back on within 2 seconds.

DSP and matrix conguraon

The amplier comprises a comprehensive range of funcons that

can be setup in two ways.

• Automac - without the use of any app or soware.

• Advanced - use the soware to set more parameters and

opmize the funconality.

This is a very easy way to congure the amplier that doesn’t require any soware. It is ideal if all you want is an amplier with a at frequency response that can monitored and if it is an AD model get audio routed to it with third party soware. The automac setup will set limiters so that a channel reaches the

maximum capacity of the power supply with -4 dBu balanced analog

input (or -6 dBFS for Dante/AES67). This means that it also adjusts the gain so that the amplier has the gain needed for all channels. The way to “assign power” is then simply done by adjusng the level of the content to the dierent channels. It will also set the high pass lters automacally. The cuto will be

selected so that frequencies below the resonance frequency as well as frequencies that saturate transformers in Hi-Z loudspeakers will

be aenuated.

Note! Automac conguraon is only possible when the amplier is in its factory default mode. Factory default is indicated by 5 seconds long blinks of the 70V and 100V LEDs. In order to restore Mezzo's factory default mode, press and hold the mode buon on the rear panel for 10 s.

Press the mode buon unl it fast blinks twice aer 2 s, release it within 2 s aer it has blinked. This will trigger an automac impedance

measurement taking 1 s per channel. This will be made at a level that is

high enough to properly measure an 8 ohm loudspeaker. If the impedance

is higher the measurement might be deemed to be too noisy and it will

then repeat itself automacally. Please note that it may generate an SPL exceeding 95 dB if the loudspeakers are sensive enough. The impedance measurement will automacally set warning thresholds

monitoring change. It will also set the limiters so that the channel can

play as loud as the design and model allows, without distoron.

No channel will ever be assigned limiters that exceed the power

of the power supply. The main reason for selecng the maximum voltage is to ensure that 25/70/100V loudspeakers will get the

power selected on their tapping if a channel is using less power than it can deliver.

If the applicaon is 25V or 70V, then there is a risk that the limiters

get set too high if the connected load isn’t requiring full power. This

Press the mode buon unl it fast blinks (3 mes) aer 5 s, release it within 2 s aer it has blinked. This will reset the amplier to autoIP and it will toggle the Ethernet mode and update the “Switched”

indicator:

• Unlit: This is the default “split mode”. The internal Ethernet

switch is disabled => the two ports are not connected and the

right port is then internally assigned for Dante/AES67. The le

port is only for control/monitoring.

• Lit: The internal Ethernet switch is enabled => the two ports are connected and will both work for Dante and control/monitoring. It means that you only need to connect with one cable for control and audio. It also means that the product can be inserted in a daisy chain of other Gigabit Ethernet products as long as there is enough bandwidth.

Step 4 - Roung and control via GPI

Dante/AES67 (AD models)

Dante &/ AES67 is enabled and it has priority over the corresponding

analog input if there is an audio signal coming over the network.

This could be congured in the Dante Controller or in a third party

plug-in.

4 Channel models

The analog 1 is always a mix on the unbalanced and the balanced analog 1; same with analog 2. The unbalanced input will get a 6 dB boost so that normal unbalanced sources will deliver enough level

to drive the amplier to full power. Otherwise the amplier will have straight 4 in 4 out roung and the 4 GPI inputs can be used with a 10kohm passive pot to aenuate the levels. If a dierent roung or a dierent funconality of the GPI pins is desired, then the soware needs to be used redene the funconality of the GPI pins. Please look at the Advanced conguraon (with soware) instead.

2 Channel models

The default here is that

• Whatever signal is delivered to output 1 is also delivered to

output 3 (but without the highpass lter). The level of these outputs can be aenuated with GPI1.

• Whatever signal is delivered to output 2 is also delivered to

output 4. The level of these outputs can be aenuated with GPI2.

Inputs 1 and 3 are mixed. Inputs 2 and 4 are mixed. This means that a balanced or unbalanced source can be used. It’s possible to

defeat this mixing by connecng GPI3 to GND. When this is done GPI4 denes which input signal pair is used with an external contact

closure between GPI4 and GND. Open → the balanced inputs are used; Closed → the unbalanced inputs are used.
