3.1 Features and functions

– 4‑channel amplifier (V600:4) / 2-channel (V600:2) amplifier with a total powerTANK

capacity of 600W.
powerTANK is a reservoir of available amplification power that is deployed flexibly across all
amplifier channels. There is no need to set up the powerTANK as it adapts to the
requirements of each zone or output without extra manual configuration of each individual
channel.

– Variable Load Drive (VLD) providing the same power into 4Ω, 8Ω, 70V or 100V
Variable Load Drive (VLD) ensures that the powerTANK capacity is utilized efficiently,
providing consistent power to any channel with different loads.

– dualCOOL convection cooling with additional intelligent fan in case of extreme thermal

conditions
The dualCOOL thermal design means that the amplifier typically operates as a convection
cooled amplifier, but in extreme thermal conditions the amplifier is also equipped with an
intelligent multi‑speed fan to ensure maximum performance and reliability in any
application.

– ecoRAIL and APD deliver significant reduction in power consumption
ecoRAIL’s power consumption is similar to a regular standby level, yet ecoRAIL still
produces audio output suitable for background music levels, and the Auto Power Down
(APD) mode can be engaged to further reduce power consumption to less than a watt when
there is no signal present for extended periods.

– Line input single cable solution for easy installation
The single cable installation feature is compatible with AES72‑1E (RJ45 connectors) wired
devices. This solution provides easy installation for all four channels of the V600:4 / both
channels of the V600:2 without needing to wire all the connections individually.

– Advanced Protection features and PFC to ensure reliability
Equipped with a PFC power supply and protection features usually reserved for the
professional power amplifiers, means that the amplifier resists complete shutdown
situations and will always perform at its best under all conditions.

Ventilation (for all models)

The airflow direction is side-to-rear. In general, setting up or mounting the power amplifier
has to be done in a way that fresh air can enter unhindered at the side and exhausted air
can exit at the rear. When installing the power amp in a case or rack system, attention
should be paid to these details to provide sufficient ventilation.

Figure4.9: Rack mounting of several V series amplifiers. Illustration of the V600:4 model.

– Allow for an air duct of at least 60mm between the rear panel of the power amplifier

and the inner wall of the cabinet/rack case.

– Make sure that the duct reaches up to the cabinets or the rack case's top ventilation

louvers.

– Leave room of at least 100mm above the cabinet/rack case for ventilation. Since

temperatures inside of the cabinet/rack case can easily rise up to 40°C during
operation of the power amp, it is mandatory to bear in mind the maximum allowable
ambient temperature for all other appliances installed in the same cabinet/rack case.

Caution!

Blocking/closing the power amp's ventilation louvers is not permissible. Without sufficient
cooling/ventilation, the power amplifier may enter protect mode.
Keep ventilation louvers free from dust to ensure unhindered airflow.

Notice!

Do not use the power amplifier in direct sunlight or near heat sources, like heater blowers,
stoves, or any other heat radiating devices.

Installation manual

2024.01 | V03 | F.01U.402.248

22 en | General installation procedures V Series

For fixed amplifier installations in a device control room that incorporate a central
air‑cooling system or air conditioners, calculating the maximum heat emission may be
necessary. See also Mains operation and resulting temperature, page 23.

4.5 Fan cooling

The device is designed for desktop operation without the need to run the fan, using
convection cooling. This ensures silent running in most conditions.
The temperature of the power amp's channels are supervised and monitored, as well as the
power supply and control unit section. These parameters determine the fan activation to
prevent output limiting from occurring.
The fan has two optimized performance levels for low and high and use the same criteria to
determine the appropriate level of force cooling required.
The rotation of the fan is supervised. In case of a lock condition where the fan is not
rotating, this is indicated with flashing warning LEDs on the front panel and the Fault relay.
However, even in such a condition the amplifier will operate without switch‑off or reduction
if supervised and monitored levels are within the range of silent running parameters.

V Series General installation procedures | en 23

4.6 Mains operation and resulting temperature

The power drawn from the mains network is converted into output power to feed the
connected loudspeaker systems and into heat. The difference between power consumption
and dispensed power is called power dissipation (Pd). The amount of heat resulting from
power dissipation might remain inside of a rack‑shelf and needs to be diverted using
appropriate measures.
Mains operation and resulting temperature tables allow the determination of power supply
and cabling requirements. The tables are meant as auxiliary means for calculating
temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary.
The column Pd lists the leakage power in relation to different operational states. The column
BTU/hr lists the dispensed heat amount per hour.

Figure5.1: Output mode configuration (channel 3 and 4 for V600:4 only)

100 Volt and 70 Volt direct drive modes

The use of either the 70V or 100V modes allow connection of high impedance (HZ)
loudspeaker lines without using output transformers (direct drive). In this case the
maximum number of loudspeakers connected to an output channel is only limited by the
amplifier channel output power.
It is recommended that this mode should be used if the distance between amplifier and
speaker is larger than 50m of cable distance (approx. 150ft) and/or a high number of
speakers with transformers are used.
When 100V or 70V is selected a 50Hz High Pass filter is automatically activated to reduce
the possibility of loudspeaker transformer saturation to ensure the best performance.

8Ω mode

In 8Ω mode the power amplifier reaches rated output power having a load of 8Ω
connected.

4Ω mode

In 4Ω mode the power amplifier reaches the rated output having a load of 4Ω connected
(e.g. one 4Ω speaker or two 8Ω speakers in parallel). These configurations can be driven
by each amplifier channel. This mode usually used if multiple speakers with medium or
low‑power rating are driven in low impedance mode (LZ).

5.1.2 Set the input routing (DUAL / PARALLEL / IN1 to ALL)

DUAL and PARALLEL modes are selected for channels 1‑2 and separately for channels 3‑4,
using the DIP switch in the Up position for “DUAL” mode or the Down position for
“PARALLEL” mode. IN1 to ALL affects all channels. If IN1 to ALL is active, it overrides the
setting of DUAL/PARALLEL switch.

Figure5.2: Input routing configuration (channel 3 and 4 for V600:4 only)

DUAL mode

In DUAL mode, the two adjacent channels controlled via the DIP‑switch are completely
independent from each other. Using the input level controls on the power amp’s rear panel
allows independently adjusting the channels’ amplification.

PARALLEL mode

In PARALLEL mode, the inputs of the channels CH1‑2 and/or CH3‑4 are directly linked. The
audio signal has to be applied to the input connectors of either CH1 resp. CH3. Input level
control for CH1 controls CH1 and CH2 at the same time. Respectively level control CH3
affects CH3 and CH4..

IN1 to ALL (V600:4 only)

IN1 to ALL allows the use of input 1 to be sent to all amplifier channels. IN1 to ALL is
configured as either ON or OFF using the IN1 to ALL DIP switch at the rear of the device.
Level control CH1 affects the volume of all output channels at the same time.

– HP100

The HP100 implements a high-pass filter with a 24dB/Oct slope at 100Hz within the
signal path. It is particularly suited for speech and voice announcements, as it
effectively attenuates undesirable low-frequency signals, such as microphone handling
noise.

– HP150

The HP150 implements a high-pass filter with a 24dB/Oct slope at 150Hz within the
signal path. Designed for implementation in a 2-way system, working in conjunction
with a compatible subwoofer to further diminish low-frequency content. This
configuration is especially useful for applications involving paging horns and very small
ceiling speakers, where minimizing low-frequency content is desirable.

– LP150

The LP150 implements a low-pass filter with a 24dB/Oct slope at 150Hz within the
signal path. It is intended for use in conjunction with a subwoofer, utilizing the HP150
settings to drive matching speakers.

– FLAT is suitable for full-range operation. However, for 4 and 8Ohm operation, a 30Hz

high-pass filter (with a slope of 24dB/Oct) is applied in the signal path to attenuate
extremely low-frequency noise. In the case of 70V and 100V operation, this high-pass
filter is set at 50Hz to avoid transformer saturation.

5.1.4 Set the energy safe option (APD)

The APD (Auto Power Down) automatically places the amplifier into a low power standby
mode after a period of inactivity when signal, such as a music source, is not present for an
extended period.
The threshold level of the APD is -45dBu* and will automatically activate standby if the
signal is constantly below this level for 25min across all inputs.
The amplifier is woken from APD to full activity by:
– Signal source (music) above -40dBu threshold.
– Pressing the front panel power button.
– If configured, Remote ON wakes the amplifier from APD through a remote button.
APD is configured as either ON or OFF using the APD DIP switch at the rear of the device.

*Activation level depends on several variables including the level controller position.

-45dBu is an estimate based on a 0dB position of the level control.

Notice!

For activating the device all input channels are monitored, regardless of routing switches or
level setting.

Refer to

– Indicators, controls and settings, page 25

5.1.5 ecoRAIL

ecoRAIL is a dedicated low‑voltage rail supply in the amplifier that significantly reduces
power consumption and increases power efficiency. ecoRAIL is permanently configured, so
there is no need to activate or set up this function.

5.2.1 Audio inputs

Audio input connectors are either Euroblock type for 2‑channels per connector, or
4‑channels via the line input RJ45 connector. Both connections are in parallel, meaning they
can be either used to input signal or to loop through.

Euroblock inputs

Euroblock inputs are electronically balanced. Whenever possible, using balanced audio
signal feeds at the input of the power amplifier is always preferred. Unbalanced connections
should only be used if the cables are very short and no interfering signals are to be
expected in the vicinity of the power amplifier. In this case, bridging the screen (shielding)
and the pin of the inverting input inside of the connector is mandatory. Otherwise, a 6dB
drop in level, hum and hiss noise could result. Due to their immunity against external
interference sources, such as dimmers, mains connections, HF-control lines, etc., using
balanced cabling and connections is always preferable.

Notice!

You must flip over the Euroblock input connector when inserting the connector to the
device (screw holes of the terminal block facing downwards).

5.2.2 Line input RJ45

The line input RJ45 connection can be used for an input of four (V600:4) resp. two (V600:2)
audio channels via a single cable, or as audio output/through when the Euroblock inputs are
in use. This allows one set of inputs from the Euroblock connections to go to another
amplifier. The pin out is compatible with any AES72‑1E device.
– Compatible with standard CAT5e or CAT6 wiring. It is recommended to use a quality

shielded STP cable for increased distances over 5m to 25m to reduce audio and signal
degradation by maintaining balanced signal.

The wiring of AES72-1E is below.

Caution!

Do not connect the line input RJ45 with Ethernet, CAN bus, Call station, or even PoE
powered ports!
Noise can occur which may damage speakers or the amplifier.

5.2.3 Power outputs

The output connectors are 2 Euroblock type for 2‑channels per connector. This allows an
easy pre‑wiring of the cables outside the rack and a fast - one connection for multiple
channels at once, without the danger of wiring errors.

Warning!

It is not allowed to interconnect terminals of different channels!

Caution!

For compliance to UL62368‑1 and CAN/CSA C22.2 No. 62368‑1 all loudspeaker wiring must
be Class2 wiring (CL2); this requirement does not apply for compliance to EN/
IEC62368‑1.

Caution!

Amplifier outputs may carry output voltages up to 100V
or wiring may result in an unpleasant sensation. The external wiring of these terminals
requires installation by an instructed person.

5.2.4 Ready/Fault relay

The Ready/Fault relay is a potential free relay toggle for READY or FAULT indication. This
allows the amplifier to notify an external device or indicator that the amplifier status is
either “RDY” (all is ok) or “FLT” (fault) and may not be functioning correctly. The next table
explains the relay setting for the different operation and error modes.

5.2.5 Remote on

REMOTE ON provides a simple way to remotely power-on/off the power amplifier. REMOTE
ON overrides front panel power button when activated.
This can be used by an external device or a simple switch that can be located away from the
amplifier for convenience.
– Leaving the pins of REMOTE ON socket “open” (nothing connected) the device works

with the front panel power button.
– See figure A below.

– When connecting the pins, the device is enforced to power on. This overrides the

operation of the front power button.

– See figure B below.
To configure the amplifier so that users cannot turn off the device (avoiding user error),
simply wire bridge the two pins together, then the front panel power button is permanently
overridden.

Refer to

– Indicators, controls and settings, page 25

5.2.6 Mains power

The power amplifier receives its power supply via the MAINS IN connector. Only the
provided power cord may be used. The amplifier is equipped with a wide range power
supply. Relevant technical data regarding mains power consumption can be found on the
product label on the rear‑side of the amplifier.

Notice!

When power is restored, the device will continue in its last known mode of operation.

Caution!

During installation, always separate the power amplifier from the mains socket! Only a
correctly installed and grounded wall mains outlet must be used.

Caution!

The front power button doesn't disconnect the device from mains. The only way to
switch‑off mains entirely is to remove the power plug.

6.1 Power on

The device can be activated by pushing the power button on the front panel. Speaker
system switch‑on is delayed by approximately three seconds via output relays, effectively
suppressing any possible power‑on noise, which otherwise might be heard through the
loudspeakers.

– See also Remote on, page 36.

6.2 Input level control

Adjustment of amplifier to source.

– Default is middle position. Full clockwise spends additional 6dB to drive the amplifier

even from weak sound sources.
The level control is assigned with the physical input, not the output channels. If routing
PARALLEL or IN1 to ALL is used, the level control is same for all channels.

Dynacord

Notice!

The level control of the unused input is ineffective. If however independent level control is
desired, the DUAL routing should be used instead and the inputs wired as parallel.
