Your ampliﬁer is ﬁtted with a standard IEC 60320-C14 socket for mains connection. Use the mains cable supplied to power up the unit.

NOTE: Your unit must always be earthed!

Speaker Outputs

The class D ampliﬁer output features 100V Line, 70V Line or 4 Ohm low impedance operation.

IMPORTANT: Remove the speaker connector link if operating the ampliﬁer

in 4 Ohm operation.

NOTE: Only one output type should be used at a time.

RS232 Communications Port

The RS232 port is designed to be connected to an external control system or to a remote PC. Using an RS232 converter (not supplied), connect to this port to communicate with the ampliﬁer from the PC software application or via serial commands. The PC software application allows for real time monitoring and conﬁguration of the ampliﬁer.

Consult the Software Control Over RS232 setup section of this manual for further details of this control.

External Mute, Standby and Fault

External Mute

Connect this input to ground (GND) to mute ampliﬁer channels.

Consult the External Mute section of this manual for further detail of this control.

Standby

Connect this input to ground (GND) to enable standby mode.

Consult the Standby Input section of this manual for further detail of this control.

Fault

This active low output indicates a fault in the ampliﬁer. There are two possible faults that can be indicated:

•

The ampliﬁer has gone into thermal shutdown due to a measured high temperature

•

The ampliﬁer has detected an overload condition on the speaker terminals

Consult the Fault section of this manual for further detail of this control.

Input Channel Clip LEDs

The input channel clip LEDs are used to indicate that the input signal is being clipped. If the input is clipping, reduce the signal by turning the attenuation pot counter-clockwise (when viewed from rear) until the clip LED ever so slightly turns on with an input source present.

The input source should be representative of the audio that will be used in the system on a daily basis.

CONTROLS, CONNECTORS & INDICATORS

Input Signal Attenuation Pot

The fully clockwise position (when viewed from rear) of the input signal attenuation pot provides no attenuation (ie 0 dB). Turning the pot counter clockwise provides a logarithmic attenuation all the way to -128 dB.

Phoenix Balanced Input

A balanced male 3-pin (3.81mm) Phoenix type connector is provided on each input channel.

Consult the Balanced Input Wiring section of this manual for further detail of this control.

Ground Lift

Use the DIP switches to control the grounding of the audio inputs. The switch for the given channel is pushed down to connect the input signal ground with the mains safety ground. The piano DIP switch is in the lift position (ie up) when the input ground needs to lifted from the mains safety ground to prevent circulating earth loops.

If at anytime a hum or unwanted noise is experienced then the input should be conﬁgured so that the input signal ground is lifted from the mains safety earth. This minimises the circulating ground loop current by adding in an impedance which results in signiﬁcantly less loop voltage drop being ampliﬁed by the ampliﬁer.

HSP SERIES INSTALLATION AND OPERATION MANUAL

INSTALLATION

Power Requirements

Power consumption for your model of the HSP series ampliﬁer is indicated on the rear panel for 1/8th output power.

Ensure that your mains voltage is the same as the rear panel mains voltage marker (+/- 10%).

Mounting

The HSP series ampliﬁers are one or two rack units high (1U) (2U) and will ﬁt a standard EIA 19” or rack.

Typically ampliﬁers may be stacked directly on top of each other with no need for spacing between units, unless installed in high ambient temperature environments where a single rack unit space between ampliﬁers will assist cooling further.

Cooling

The HS120P is convection cooled and does not require any special consideration.

The HS250P, HS2120P, HS2250P, HS4120P and HS4250P ampliﬁers are cooled by axial fans which draw air inside the ampliﬁer and expel the heated air outside the ampliﬁer. These ampliﬁers offer variable speed fans which run at half speed up to full speed when the internal heatsink temperature increases.

An unrestricted airﬂow into and out from the ampliﬁer must be provided. Any restriction of the air ﬂow will cause heat to build up within the unit and possibly force the unit into its thermal shutdown mode.

If the ampliﬁers are to be operated in an environment where the airﬂow is restricted such as sealed racks, cooling should be supplemented by extra cooling fans to evacuate the heated air and aid the ﬂow of cool air through the unit.

Balanced Input Wiring

1 2 3

INPUT 1

IMPORTANT: Do not directly connect pin 3 on the ampliﬁer’s input to the

ampliﬁer’s chassis, speaker ground or power ground!

WARNING: Input signal ground should NOT be used as a safety

ground (earth).

The balanced input to the ampliﬁer is 3-pin conﬁguration and requires all three pins to be connected. Only high quality twin-core shielded cable should be used.

Pin 1 is the left most pin when viewed from the back of product.

Pin 1 = Hot (non-inverting or in phase)

Pin 2 = Cold (inverting or reverse phase)

Pin 3 = Signal Ground

When wiring from an unbalanced source you must ensure that pin 2 is connected to pin 3 (Signal Ground), either by linking the pins in the input connector or by the source equipment’s output wiring.

When wiring for an unbalanced source:

Pin 1 = Hot (non-inverting or in phase)

Pin 2 = Signal Ground

Pin 3 = Signal Ground

Output Wiring

When wiring to your speakers always use the largest gauge wire your connector will accept. The longer the speaker lead the greater the losses which will result in reduced power and less damping at the load. We recommend using a heavy duty, two core ﬂex (four core ﬂex if bi-amping) 10 to 12 gauge (2mm2 to 2.5mm2 or 50/0.25 or equivalent) as a minimum.

Hum Problems

Most equipment is designed for minimum hum when used under ideal conditions. When connected to other equipment, and to a safety earth in an electrically noisy environment, problems may occur.

The three ”E”s of hum and hum related noise which can plague your audio system are:

a) Earth loops

b) Electromagnetic radiation

c) Electrostatic radiation

Earth loops can arise from the interfacing of the various pieces of equipment and their connections to various safety earths.

This is by far the most common cause of hum, and it occurs when source equipment and the ampliﬁer are plugged into different points along the safety earth where the safety earth wiring has a current ﬂowing through it. The current ﬂowing through the wire produces a voltage drop due to the wire’s resistance. This voltage difference between the amp earth and source equipment earth appears to the ampliﬁer’s input as a signal and is ampliﬁed as hum. There are three things you can do to avoid earth loop problems:

•

Ensure the mains power for the audio system is “quiet” i.e. without equipment on it such as air-conditioning, refrigeration or lighting which may generate noise in the earth circuit.

•

Ensure all equipment within the system shares a common ground/ safety earth point. This will reduce the possibility of circulating earth currents, as the equipment will be referenced to the same ground potential.

•

Ensure that balanced signal leads connecting to the ampliﬁer are connected to earth at one end only.

Electrostatic radiation capacitively couples to system elements, causing an interference voltage that mainly affects higher impedance paths, such as ampliﬁer inputs. The source is generally a nearby high voltage, such as a mains

lead or a speaker lead. The problem can usually be reduced by moving the offending lead away, or by providing additional electrostatic shielding (i.e. an earthed conductor which forms a barrier to the ﬁeld).

Electromagnetic radiation induces interference currents into system elements that mainly effect lower impedance paths. Radio transmitters or stray magnetic ﬁelds from mains transformers are often the cause of this problem. It is generally more difﬁcult to eliminate this kind of interference, but again, moving the source away or providing a magnetic shield (i.e. a steel shield) should help.

IMPORTANT: All signal source equipment should be adequately earthed. This not only ensures your safety but everybody else’s as well. Faults can and do occur in mains connected equipment where the chassis can become “live” if it is not properly earthed. In these instances, the fault in a “ﬂoating” (ungrounded) piece of equipment will look for the shortest path to ground, which could possibly be your ampliﬁer’s input. If the fault current is large enough, it will destroy the input to your ampliﬁer and look for the next available path, which may be you!

Before making any connections to your HSP Series ampliﬁer, observe the following:

•

Ensure the mains voltage supply matches the label on the rear panel of your ampliﬁer (+/- 10%).

•

Ensure that the power switch is OFF.

•

Ensure that all system grounds (earth) are connected from a common point. Avoid powering equipment within a system from multiple power sources that may be separated by large distances.

•

Check the continuity of all interconnecting leads to your ampliﬁer; ensure that there are no open or short circuited conductors.

•

Ensure that the power handling of your load (speakers) can adequately cope with the power output of the ampliﬁer.

Powering Up

REMEMBER: The ampliﬁer should be the last piece of equipment that you turn on and the ﬁrst piece of equipment that you turn off.

Sensitivity

The input sensitivity of your HSP ampliﬁer when the attenuation pot is at maximum position (fully clockwise) is nominally:

1Vrms for rated power into a 4 Ohm load

Each channel of your HSP ampliﬁer has a nominal balanced input impedance of 20kOhms (@1kHz) and should not present a difﬁcult load for any signal source.

Your signal source (i.e. the equipment feeding signal to the ampliﬁer) should have an output impedance of 600 Ohms or lower to avoid unwanted high frequency loss in the cabling.

BASIC SETUP & OPERATION

Fault Finding

Status Indicator

If the blue STATUS LED is ﬂashing instead of remaining on then a speciﬁc system state is being displayed. See the table below on the meaning and of the system state.

The status LED should indicate the following:

LED Meaning Indication

Blue On Normal Operation LED solid on. Indicates that device is powered and that no faults exist.

Blue Slow Flash Standby Mode Flash LED: On for 50ms, Off for 4s

Blue Flash Error Mode LED Off for 2s followed by a ﬂash count of the error code, On for 300ms, Off for 300ms. Multiple errors will be indicated in

consecutive error sequences. Refer to table below for list of error codes.

The list of error codes is:

Error Code STATUS LED error flash count

Conﬁguration error 1

Nor Flash image failure 2

Nor Flash read / write failure 3

Power Ampliﬁer initialization failure 4

DSP failure 5

Bootloader failure 6

Protect Indicator

The following table indicates the meaning of each protection mode:

LED Meaning Resolution

Yellow ﬂashing Ampliﬁer temperature warm None required

Yellow on Ampliﬁer temperature hot None required

Red ﬂashing Ampliﬁer over temperature* The ampliﬁer has shutdown. It will automatically restart once it has cooled down

Red on Ampliﬁer protect Check the speakers connected to the ampliﬁer are correctly wired. Power cycle the unit and retry.

* In the advent of a thermal overload, the internal operating temperature of the ampliﬁer has exceeded a safe level of operation. The fan will continue to run and once

the ampliﬁer has cooled it will return to normal operation.

Signal Indicator

The following table indicates the meaning of each signal mode:

LED Meaning Resolution

Green on Audio signal present None required

Green off No audio signal present Increase the input audio level

Green ﬂashing Ampliﬁer channel is set to mute Unmute the channel using the PC application
