CONTROLS, CONNECTORS & INDICATORS

5 6

FRONT PANEL

The AMP Series differ only slightly across all models and all share the same features on their front panels.

The functions of the controls and indicators are as follows:

1

Power Switch

Press the switch to up for power on and down for power off. At start-up

(turn-on), the input to the amplifier is muted for approximately two seconds.

2

Power Indicator

This blue LED will illuminate and indicates that the amplifier is on and receiving mains power.

3

Protect Indicator

This yellow LED indicates a problem with the amplifier or that it has over heated. In the advent of a thermal overload, the internal operating temperature of one or both amplifier channels has exceeded a safe level of operation and the channel will be automatically muted. The fans will continue to run and once the effected channel/s have cooled, they will unmute and return to normal operation.

The AMP series is also fitted with DC protection, if there is a DC voltage at the output the protection LED will glow yellow.

It should be noted that the minimum load for the amplifier is 4 ohms per channel (8 ohms bridged).

If an overload occurs, the amplifier will run into a current limit mode, restricting the excess current beyond set limits.

4

Clip Indicator

This red LED will illuminate when clipping occurs. Clipping can occur under extreme operating conditions such as:

• complex or very low loads

• over driving the amplifier

NOTE: The amplifier is not damaged by running into clipping, but speakers may be. To maximise the life of your speakers, try to keep clipping infrequent.

5

Signal Indicator

This green LED will illuminate when an input signal is detected.

6

Fan Grill

This is where air is drawn into the amplifier for cooling.

NOTE: You should always ensure that the fan grille is kept clean and the foam is free from dust or lint. This will ensure longer operation of your amplifier and reduce the possibility of it prematurely going into thermal shutdown mode. Refer to the “Maintenance” section on page 11 for further information.

TOP PANEL

The switches on the top panel are accessed through a vent opening. Use a small rod through the vents to move the switches to the desired positions.

NOTE: Only make changes to these switches when the unit is powered off.

7

Bridge / Stereo

Turn the bridge switch on to enable BRIDGED mode. In this mode your amplifier will only accept signal applied to channel 1’s balanced input. The level is controlled by the channel 1 level potentiometer and/or VCA attenuator.

The output from channel 2 will automatically be of the opposite polarity

(reversed phase) and speaker termination should be sourced from the 4Ω output of each channel respectively. (see Speaker Connector Wiring Diagram)

8

Limiter Switch

Turn the limiter switch on to engage the clip limiter circuitry. The threshold level is referenced to the supply rail and the output voltage is sampled allowing true clip detection and limiting.

9

VCA Switch

Turn the VCA switch on to engage the voltage controlled attenuation input.

10

Signal Ground Lift Switch

When this switch is engaged it disconnects signal ground from the respective input channel.

It is intended to be used when “hum” is caused by earth loops (due to different ground potentials between source equipment and the amplifier) or stray magnetic field pick up on the input ground/shield wiring. (It does not interrupt signal ground continuity on the strapping connector). The amplifier should be turned off before engaging this switch!

5

Speaker Outputs

The output for each channel can be 100V Line, 70V Line or 4 Ohm low impedance. Only one output type should be used per channel.

AMP SERIES CONSTANT VOLTAGE INSTALLATION AUDIO POWER AMPLIFIERS INSTALLATION AND OPERATION MANUAL PAGE 7

INSTALLATION

Power Requirements

Power consumption for your model of the AMP 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 AMP series amplifiers are one rack units high (1U) and will fit a standard

EIA 19” rack. A rack rear support bracket is supplied and must be installed when rack mounting the amplifier. The rear support bracket should be installed to the rack (rear rails) prior to mounting the amplifier. Failure to mount or support the amplifier correctly may lead to chassis damage which is not covered by warranty.

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 were a single rack unit space between amplifiers will assist cooling further.

Cooling

Your AMP Series amplifier is cooled by axial fans which draw cool air from the front of the amplifier and expels the heated air out the rear of the amplifier.

These amplifiers offer variable speed fans which run at half speed up to full speed when the internal heatsink temperature exceeds 60° C (128° F).

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, the cooling should be supplemented by extra cooling fans to evacuate the heated air and aid the flow of cool air through the unit.

Input Wiring

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 is not to be used as a safety ground (earth).

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

Pin 1 = HOT (In Phase - non inverting).

Pin 2 = COLD (Reverse Phase - inverting).

Pin 3 = GROUND / SHIELD.

When wiring from an unbalanced source you must ensure that pin 2 is connected to pin 3 (input 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 (in phase with the amplifier’s output)

Pin 2 = GROUND/SHIELD (joins to pin 3).

Pin 3 = GROUND/SHIELD

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 will be, resulting 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.

Speaker Outputs

Each channel has a 6 pin output screw terminal with a pre-fitted link between the 4Ohm and high voltage line transformer.

IMPORTANT: Ensure the link is fitted if you are using the 70V or

100V output.

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) Electrostatic radiation, b) Electromagnetic radiation, and c) Earth loops

Electrostatic radiation capacitively couples to system elements, causing an inter- ference 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.

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.

AMP SERIES CONSTANT VOLTAGE INSTALLATION AUDIO POWER AMPLIFIERS INSTALLATION AND OPERATION MANUAL PAGE 9

OPERATION

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 AMP 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.

Before operating your AMP Series amplifier, ensure that:

• The BRIDGE Switch is not engaged if you are not running the amp in bridged mode.

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.

We recommend turning the attenuators on your amplifier down when turning the unit on.

Sensitivity

Your amplifier is a linear device operating with a fixed input to output voltage gain (less attenuation). The maximum output voltage swing is determined by the applied mains voltage, load, load type and the duty cycle of the applied signal.

The input sensitivity for your AMP Series amplifier when the level control is at maximum position (fully clockwise) and the VCA is disabled is nominally:

+2.2dBu (1.00 volts in) for rated power into a 4 Ohm load.

Each channel of your AMP Series amplifier has a nominal balanced input impedance of 30kOhms (@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.

PAGE 10 AMP SERIES CONSTANT VOLTAGE INSTALLATION AUDIO POWER AMPLIFIERS INSTALLATION AND OPERATION MANUAL

MAINTENANCE

Maintenance

Only competent or qualified persons should attempt any service or maintenance of your amplifier. Your AMP Series amplifier will need minimal maintenance. No internal adjustments need to be made to the unit to maintain optimum performance. To provide years of unhindered operation we suggest a maintenance inspection be carried out on a regular basis, say every 12 months or so.

Fans

Due to the openness of the air path through your AMP Series amplifier, very little dust should settle within the amplifier. The unit has been designed so that any dust and/or foreign particles that do settle within the amplifier will not unduly hinder the cooling of the amplifier.

The grille in front of the fans will act to limit the amount of dust and lint entering the amplifier. You will find in time that there will be a build up of dust and lint on the grille which may start to hinder the airflow through the amplifier.

You should periodically remove the dust and keep the grille clean. Removal of dust from the rear grille will also aid cooling.

Over time, dust may build up on the leading edge of the fan blades and reduce their cooling efficiency. The time taken for this to happen will depend on the environment and the amount of use.

The fan blades are accessible once the lids are removed and can be easily cleaned. You need only hold the fan rotor still and wipe the dust off the blades.

Many users stall the fan and use compressed air to blow the dust off the fan blades. It is important to note that the fan blades must be held still whilst blowing air over the blades otherwise you may burn out the bearings in the fan.

Fuses

There are two rail fuses provided internally per amplifier channel. These rail fuses are in series with the positive and negative output supply and provide overall protection for the output stage. If the amplifier is subjected to heavy use such as short circuits, 1 Ohm or bridged 2 Ohm loads, these fuses will eventually fatigue and may require replacing to ensure they do not fail at an inconvenient time.

WARNING: Make sure the unit is off and is unplugged from the mains. Give the main filter capacitors time to discharge before removing lids and inspecting the fuses.

You should replace the fuse if the element is sagging or discoloured. Only ever replace with the same type fuse and current rating.

When checking for a failed fuse, do not rely on visual inspection alone. You should use an Ohm meter to check continuity
