The HH Electronics SP48 is a fully featured 4-IN/8-OUT digital speaker management

system. Featuring 4 analogue inputs and 8 analogue outputs, each managed by a

powerful DSP Engine.

The four input channels provide 30-band parametric EQ, Noise Gate, up to 420ms Delay

and RMS Compressor.

Each of the 8 outputs offers 7-band parametric EQ, crossovers with slopes from 6dB/oct

up to 48dB/oct, 128ms of Delay and 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 SP48 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 4 input, 8 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.

•Switched mode power supply with 100-240V worldwide operation.

•1U rack height

To quickly get started using the HH SP48 follow the following steps:

1. Make all initial connections with the power OFF on all equipment. Ensure any

volume, level, or gain controls are at minimum.

2. Connect your signal source output to the inputs of the SP48.

3. Connect outputs 1-8 from the SP48 to the inputs of your power amplifiers or

powered loudspeakers.

4. Starting at the signal source, turn on equipment.

5. As soon as the SP48 is turned ON the device model name will appear in the LCD

screen

6. A status bar will show the progress of the SP48 initialization process

7. After the SP48 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 SP48.

10. Turn up the signal source until audio is heard through the system.

Here are some example system connections for the SP48.

Passive TNA System

In this example, the SP48 is setup to drive a passive TNA system using HH M-Series

amplifiers. The four 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

two are driving four TNA-1200S with two per channel for the mid band frequencies.

Another two are driving 8 TNA-2051s and the last two are driving two TNi-W8PROs for

balcony fills.

Passive TNi-C6 System

This setup shows the SP48 connected to 4 M-series amplifiers, which in turn are each

connected to 10 TNi-C6s. The system shown here has various uses such as bars, cafes or

offices and can be spread over multiple rooms.

Active TNA System

This example shows the SP48 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 SP48 more freedom for EQ adjustments to fit the room environment. The

last six channels are used to drive six TNA-1800SA active subwoofers. Having

independent channels for each sub-woofer allows for precise phase alignment.

Mixed TNA System

In this example the SP48 is setup for a mix of powered and passive loudspeakers. Two

outputs are used to drive two TNA-1800SA powered sub-woofers. This leaves the

remaining six outputs to drive 6 TNi-W8Pro via three M-1500A amps. This system could

be extended with multiple subs and TNi-W8PROs to easily cover a bar or club venue.

REAR PANEL

1. POWER SWITCH

Turns the HH SP48 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 SP48 before power cycling

the unit.

2. MAINS INLET SOCKET & FUSE

This is where to connect the IEC power cable included with the SP48. The SP48 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. RS485 Connections

IN and OUT ethernet connections for RS-485 remote control and linking several units. Up

to 32 SP48 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.

4. GND/LIFT

If you are getting ground loop hum from the RS-485 connections, you can use the

GND/LIFT in attempt to remedy it.

5. XLR OUTPUTS

Eight 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

Four line-level balanced female XLR inputs for input channels A, B, C and D. Connect

these to the main mixer outputs or other audio source.
