The HH Electronics SP26 is a fully featured 2-IN/6-OUT digital speaker management
system. Featuring 2 analogue inputs and 6 analogue outputs, each managed by a
powerful DSP Engine.
The two input channels provide 11-band parametric EQ, Noise Gate, Dynamic Loudness
Filter, up to 900ms Delay and RMS Compressor.
Each of the 6 outputs offers 7-band parametric EQ, crossovers with slopes from 6dB/oct
up to 48dB/oct, 340ms of Delay and RMS Compress/Peak Limiter settings.
Easy setup is assured with intuitive front panel controls and an interactive LCD display for
local setup, or a dedicated PC control interface for remote monitoring and configuration
via USB or RS485.
The SP26 loudspeaker processor is the perfect counterpart to any HH speaker system,
suitable in an array of applications, such as live sound, indoor/outdoor events, public
address, theatrical performance, and touring.
It also comes pre-loaded with expertly created audio pre-sets for use with the TNA line
array system, for easy setup straight out of the box.
FEATURES
•High performance 2 input, 6 output loudspeaker processor.
•High quality 24bit AD/DA audio converters.
•96bit DSP processor precision.
•USB port for simple programming and setup.
•Linkable inputs and outputs for easy stereo configuration.

To quickly get started using the HH SP26 follow the following steps:
1. Make all initial connections with the power OFF on all equipment. Ensure any
volume, level or gains controls are at minimum.
2. Connect your signal source output to the inputs of the SP26.
3. Connect outputs 1-6 from the SP26 to the inputs of your power amplifiers or
powered loudspeakers.
4. Starting at the signal source, turn on equipment.
5. As soon as the SP26 is turned ON the device model name will appear in the LCD
screen
6. A status bar will show the progress of the SP26 initialization process
7. After the SP26 has finished it’s boot up sequence, select the preset to best match
your system setup.
8. Turn on power amplifiers, powered loudspeakers, and the rest of the system.
9. Un-mute the input and output channels of the SP26.
10. Turn up the signal source until audio is heard through the system.

Here are some example system connections for the SP26.
Passive TNA System
In this example, the SP26 is setup to drive a passive TNA system using HH M-Series
amplifiers. The two inputs come from a signal source such as a mixer or media stream.
The first two outputs are driving the two TNA-1800s subs with a LF crossover. The next
feed is driving four TNA-1200S with two per channel for the mid band frequencies. The
last two feeds are supplying the eight HF TNA-2051 with four a channel. This setup is
commonly used in stereo with the two input channels accept the left and right signals.

Active TNA system
This example shows the SP26 driving into an Active TNA system with powered speakers.
The first two channels are used to drive the TNA-2120SA MF to HF loudspeakers, these
would receive a full range signal as the on-board DSP will handle crossover frequencies,
this gives the SP26 more freedom for EQ adjustments to fit the room environment. The
last four channels are used to drive four TNA-1800SA active subwoofers. Having
independent channels for each sub-woofer allows for precise phase alignment.
6
TNi-WPRO System
In this example the SP26 is setup for a mix of powered and passive loudspeakers.
Channels 1&2 are used to drive the two TNA-1800SA powered sub-woofers. This leaves
channel 4 to 6 to drive 4 TNi-W8Pro via two M-1500A amps. This system could be
extended with multiple subs and TNi-W8PROs to easily cover a bar or club venue.

1. POWER SWITCH
Turns the HH SP26 on and off. When powering on or off the unit, the outputs and inputs
will mute to avoid unwanted pops or noise, but it is still recommended to turn off / mute
any power amplifiers or active loudspeakers connected to the SP26 before power cycling
the unit.
2. MAINS INLET SOCKET & FUSE
This is where to connect the IEC power cable included with the SP26. The SP26 uses a
SMPSU which allows for 100-240V~ Worldwide AC operation.
The FUSE is accessible from the holder. Only replace the fuse with the correct type and
rating, T800mA L 250V
3. GND/LIFT
If you are getting ground loop hum, you can use the GND/LIFT in attempt to remedy it.
4. RS485 connections
IN and OUT XLR connections for RS-485 remote control and linking several units. Up to 32
SP26 can be connected in the same network. The RS-485 section also has its own GND lift
switch if ground loop hum is induced via the RS-485 connections.
5. XLR OUTPUTS
Six line-level balanced male XLR outputs for each of the processor’s channels. Connect
these to inputs of power amplifiers and/or active loudspeakers.
6. XLR INPUTS
Two line-level balanced female XLR inputs for input channels A and B. Connect these to
the main mixer outputs or other audio source.

FRONT PANEL
7. LCD
The main LCD display works in conjunction with the NAV controls and can be used to
access and edit the local SP26 configuration settings. This is useful if not using the control
app to configure the processor or to make quick adjustments.
8. NAV/PM1
The [NAV/PM1] control is a rotary encoder used for navigation of menus with the
processor.
9. PM2
The [PM2] control is a rotary encoder used for editing parameter values.
10.PM3
The [PM2] control is a rotary encoder used for editing parameter values.
11.ENTER
The [ENTER] button is used to enter submenus and confirm operation changes.
12.ESC
The [ESC] button is used to cancel any changes or return to previous submenus.
13.UTILITY
The [UTILITY] button is used to access the UTILITY submenus. See the SYSTEM UTILITIES
section.
14.MUTE / EDIT BUTTONS
The 8x MUTE / EDIT buttons have two modes of operation. They allow selection for
editing and control the mute status of the 2 inputs and 6 outputs.
A short press selects the input or output channel for editing. This will illuminate the blue
EDIT LED of the selected channel; a second press will deselect the channel and bring it
out of edit mode. It is possible to select multiple inputs or outputs at once for
simultaneous editing.
A long press enables or disables the mute for the input or output channel. This will
illuminate the red MUTE LED to indicate the channel is muted. Press and hold until the
MUTE LED is cleared to enable the channel again.

15.EDIT LEDs
The blue EDIT LEDs indicate the selected channels for editing. See MUTE / EDIT
BUTTONS above.
16.MUTE LEDs
The red MUTE LEDs indicate the channels mute setting. See MUTE / EDIT BUTTONS
above.
17.METERS
The METER LED displays show current signal level for the input and output. For optimal
headroom these meters should remain green. The occasional peak enabling the yellow
“LIMIT” LED is viewed as ok. Constant illumination of the LIMIT LED or the red CLIP LED
shows the signal level is too high and should be lowered.
Note Internal Gain and EQ settings can also cause the signal to increase in level, in
general it is better to cut than to boost excessively
The input meters show:
CMP, CLIP, +15dBu, +9dBu, +3dBu, 0dBu, -25dBu
The output meters show:
LIMIT, CLIP, +15dBu, +9dBu, +3dBu, 0dBu, -25dBu
18.USB
For more convenient control of the SP26, you can use any Microsoft Windows® based PC.
Encoders, Enter and ESC buttons
The HH SP26 is equipped with 3 Relative Encoders, NAV/PM1, PM2 and PM3. These
encoders allow you to navigate the user interface and edit sections of the processor. The
NAV/PM1 rotary encoder is used to navigate menus and sub-menus. The PM2 and PM3
encoders allow editing of selected parameters.
The ENTER and ESC buttons allow the user to confirm or not confirm any changes of
parameters, they are also used to navigate into and out of submenus.

FACTORY RESET
In the event of the password being lost or any other reason the user may require the unit
to be reset to the original factory settings. The FACTORY RESET will clear all settings of
the HH SP26 and return the device to the original factory setting.
Note: A factory reset of the HH SP26 will mean any user settings or previously stored
information w ill be permanently lost.
To perform a factory reset:
1. Whilst the unit is off, press and hold the ENTER, ESC & UTILITY buttons.
2. Power on the unit whilst holding these buttons.
3. The following LCD screen will appear:
4. Release the buttons and wait for the factory reset to complete.
