2.2 Network Features
PowerZone™ Control
PowerZone™ Connect ampliers are TCP/IP network
connected devices that require a wired or wireless network
connecon to access their conguraon menus. The
conguraon menus are accessed via the PowerZone™Control
Web App interface and cover Input, Zone, Output and General
Sengs funcons. The conguraon menus are fully described
in Secon 4 of this manual.

2.3 External Device Remote Control
PowerZone™ Connect ampliers are able to be controlled
remotely using the Blaze Wall-S1 control panel. The Wall-S1
is an Ethernet connected wall-mounted device able to
control Blaze PowerZone™ Connect amplier volume and
input source selecon. The Wall-S1 is powered via a POE
(Power Over Ethernet) wired connecon to an appropriately
specied network switch. A single Wall-S1 device can control
one amplier zone only, so remote control of mulple zones
requires mulple Wall-S1 devices – each one assigned to an
individual zone.
Full informaon on Wall-S1 installaon and use can be found
in the Wall-S1 installaon manual available for download from:
hps://blaze-audio.com/products/control/wall-s1/

Note: PowerZone™ Connect ampliers can be congured to
use DHCP for network connecon if required. However, if a
PowerZone™ Connect amplier using DHCP is power cycled, it is
possible that the TCP/IP network router will assign it a dierent IP
address, leaving its conguraon page inaccessible via the previous
address. If this occurs, a network scanning app can be used to
idenfy the new IP address. DHCP and Fixed IP address opon
sengs can be found in the Sengs Tab menu described in Secon
5.3.
Note: The second network socket present on the amplier rear panel
is intended for Audinate Dante®AoIP network connecon only. It
cannot be used for PowerZone™ Control connecon.

Note: FIR coecient les in either .csv or .txt format can be
imported.
• The Driver Alignment preset menu enables delay to be
applied to individual amplier outputs.
• The Polarity preset menu enables the polarity of individual
amplier outputs to be reversed.
• The Limiter preset menu enables signal liming to be
engaged or bypassed on individual amplier outputs. Clip
liming, Peak liming and RMS liming can be individually
or collecvely engaged. The Clip liming funcon oers
Fast and Normal response me opons. The Peak liming
funcon can be set to either Automac or Manual
parameter values. The RMS Limiter has default parameter
values that can be adjusted but has no automac opon.
Note: It is strongly advised that if an amplier is driving low
impedance loads (<4Ω) the Clip Limiter should be engaged and set
to Fast.
Note: In automac mode, the peak limiter parameters adjust
automacally in response to Crossover & Gain high-pass lter
sengs.
• The Output Mode preset menu enables individual
amplier outputs to be switched o or congured for Lo-Z
or Hi-Z modes. In Hi-Z modes, a high-pass lter can also
be congured and applied to the output. The number of
outputs available will depend on the amplier model, input
setup and zone setup. For example, a two output amplier
will have two outputs available if Lo-Z mode is selected but
only one output available if Hi-Z mode is selected.
Note:: Use of a high-pass lter with Hi-Z mode loudspeakers is useful
to avoid the possibility of distoron caused by low frequency line
transformer saturaon. Begin with the default lter seng of 70Hz.
If low frequency distoron is sll audible, increase the frequency
seng one step at a me unl the distoron is no longer audible.

and management of speaker preset libraries.
Note: A variety of speaker preset les are available for download
from the Blaze website: www.blaze-audio.com.
• The Security menu enables a password to be set in order
to protect against unauthorised access to the amplier
Control Web App. Password protecon is parcularly
important when an amplier is connected to a wired
network as the a WiFi password is no longer required to
gain access to Control Web App.
Note: It is recommended that a Control Web App password is
dierent from that required to gain access to the amplier via WiFi.
• The Power Management menu enables various automac
switch-on opons to be engaged. The Power Management
menu also oers med Standby and Mute funcons.
• The Output Roung menu enables specied inputs or zones
to be routed to the amplier S/PDIF outputs. The output
level can also be adjusted.
Any zone or input can be routed to either digital output,
including inputs not acvely assigned to a zone. Primary
or priority input status is immaterial. The specied input is
always routed to the specied output to be available for use
by downstream devices.
Note: The digital output funcon is especially useful when ampliers
are to be daisy chained and a specic input; a central paging mic, for
example, is required to be routed to mulple ampliers..

5.4 Setup and Signal Roung
Thanks to their network based conguraon features,
PowerZone™ Connect ampliers oer considerable versality
in terms of sources, signal roung, installaon zones and output
modes. Inputs can be freely assigned to installaon zones, and
those zones assigned freely to the available amplier outputs in
either Lo-Z or Hi-Z modes.
This versality enables, for example, one amplier
simultaneously to drive both Lo-Z and Hi-Z speakers, or for
dierent inputs to be routed to dierent output zones.
The following paragraphs describe and illustrate the
recommended procedure for conguring input, zone and
output roung. A general signal ow schemac is also
illustrated in Diagram 5O.

Conguraon
5.4.1 Input Setup
Open the conguraon Dashboard and select the Input Tab.
The Input Tab is shown in Diagram 5B.
• To edit default input names simply select and type in the
Input Name eld.
• Dene a mono or stereo input by selecng the appropriate
opon. Dening a stereo input will reduce the total number
of discrete inputs available.
• Select an input sensivity opon from the drop-down
menu: +14dB, +4dB, -10dB and ‘microphone’ opons
are available. Generally, the +14dB or +4dB opons are
appropriate for ‘professional audio’ source hardware
with balanced outputs, while the -10dB opon is more
appropriate for ‘consumer audio’ source hardware with
unbalanced outputs. The ‘microphone’ opon provides the
signicantly greater sensivity required for microphones.
Note: Only dynamic microphones are suitable for connecon.
Phantom power for condenser microphones is not provided.
• If necessary, adjust the input gain using the slider or up/
down icons. Gain adjustment is intended to be used for ne
output level adjustment following inial use.
5.4.2 Zone Setup & Roung
Open the conguraon Dashboard and select the Zone Tab.
The Zone Tab is shown in Diagram 5E.
• Select the zone to be congured. The number of zones
available and their channel format (stereo or mono) will
depend on the amplier model, input setup and output
mode (Lo-Z or Hi-Z). For example, a two output amplier
can have the following zone conguraons:
• 1 x stereo Lo-Z zone
• 2 x mono Lo-Z zones
• 1 x mono Hi-Z zone
• A four output amplier can have the following zones
congured:
• 2 x stereo Lo-Z zones
• 4 x mono Lo-Z zones
• 2 x mono Hi-Z zone
• 1 x mono Hi-Z zone + 1 x stereo Lo-Z zone
• 1 x mono Hi-Z zone + 2 x mono Lo-Z zones
Note: When congured in Hi-Z mode PowerZone™ Connect
ampliers operate in ‘bridged’ mode where the output of two
channels is combined. This means that the number of output
channels available in Hi-Z mode is half that available in Lo-Z mode .
Note: Mono signals might be mono at source, created though
combining the le and right channels of a stereo signal (summed
mono) or treang the le and right channels of a stereo signal
independently (split mono).
• Name zones by typing in the Zone Name eld.
• Adjust the zone volume if required by using the slider.
• Dene a mono or stereo zone by selecng the appropriate
opon. Dening a stereo zone will reduce the total number
of further zones available.
• Specify an input for the zone by selecng from the drop-
down menu. Selecng a stereo input for a mono zone will
automacally sum the stereo channels to mono.

Conguraon
5.5 GPIO Setup and Connecon
PowerZone™ Connect ampliers provide a GPIO socket that
enables remote control of volume, standby, mute and trigger
funcons. The GPIO connector pin funcons are described
in the GPIO Sengs menu illustrated in Diagram 5P. The
connecon of GPIO based remote volume control and
standby/mute are illustrated in Diagram 5Q and Diagram 5R
respecvely.
Note: The GPIO connector must not be used for any
unintended purpose. Amplier damage may result from
incorrect use of GPIO.
Note: Shielded cable must be used when connecng standby
switches and potenometers via GPIO.
Note: GPIO Pin 8 has a low output impedance and is able to
supply a maximum current of 10mA.
Note: GPIO Pin 1 and Pin 3 both oer ground connecons:
Pin 1 is connected directly to the amplier chassis.
Pin 3 is connected to the chassis via a 220 Ohm resistor.
The ‘so ground’ connecon of Pin 3 is potenally useful for
managing ground loops that may cause audible hum.

6. Connecons
PowerZone™ Connect amplier rear panel connecons
are illustrated in Diagrams 6a.
6.1 Mains Power Connecon
PowerZone™ Connect ampliers incorporate a power factor
corrected universal power supply and can be used with mains
input voltage from 100V AC to 240V AC, 50/60Hz. Use the
mains cable supplied with the amplier.
PowerZone™ Connect ampliers incorporate a front panel
mounted power buon. Press the buon once to switch the
amplier on or o. Ensure that all signal, GPIO and output
connecons are made before switching on the amplier.
6.2 Input Connecon
All PowerZone™ Connect amplier models provide four
balanced or unbalanced analog audio inputs and a stereo S/
PDIF digital audio input. Any input channel can be routed to any
output channel. Input roung opons can be congured via the
PowerZone™ Control Web App Input Tab. See Secon 5 of this
manual.
Analog Inputs
PowerZone™ Connect analog inputs are of line level format
with a default input sensivity of +4dBu (full output voltage
swing/sensivity) in all output modes. Depending on the
selected sensivity, the inputs can handle up to +24dBu
without clipping. Input sensivity opons can be set via the
PowerZone™ Control Web App Input Tab. See Secon 5 of this
manual.
Balanced input connecons to the ampliers are made via male
‘Euro Block’ connectors. Connecng cables to the supplied
female input connectors is illustrated in Diagram 6b.
Unbalanced input connecons to the ampliers are made via
RCA phono sockets connected in parallel with the balanced
inputs.
Diagram 6A
PowerZone™ Connect rear panel connecons.
Note: Two output amplier model connecon sockets dier only in
the deleon of channel 3 and channel 4 output connectors.
Digital Outputs
PowerZone™ Connect S/PDIF stereo digital audio output
connecons are made via a single RCA Phono socket. The S/
PDIF output signal can be routed from any input or zone and is
intended to be used for daisy-chaining PowerZone™ Connect
ampliers.
Note: See the Output Roung paragraphs of Secon 5.3.3 for more
informaon on Digital Output conguraon.
Note: 75Ω RCA Phono cables specically intended for digital audio
should always be used for S/PDIF connecons. Standard Phono
cables can be used but may not result in opmal performance.
Note: The S/PDIF output level is by default set at -10dB to reduce
the possibility of downstream input clipping.
6.3 Output Connecons
Output connecons from the ampliers are achieved via male
‘Euro Block’ connectors. Ensure that speaker connecon
polarity is correct throughout the installaon:
In the case of Lo-Z speaker connecons, posive (+) amplier
terminals should always be connected to posive speaker
terminals and negave (–) amplier terminals always connected
to negave speaker terminals.
In the case of Hi-Z speaker connecons, the two speaker cable
conductors should be connected between the posive (+)
terminal of Output 1 and the negave terminal (-) of Output 2,
and likewise for Outputs 3 and 4.
Output mode opons (Lo-Z or Hi-Z) can be congured via the
Control Web App Input Tab. See Secon 5 of this manual.
Connecng cables to the supplied female output connector is
illustrated in Diagram 6c.
