WARNING

TO REDUCE THE RISK OF ELECTRIC

SHOCK, DO NOT EXPOSE THIS

EQUIPMENT TO RAIN OR MOISTURE!

Magnetic Field

CAUTION: Do not locate sensitive high-gain equipment such as preamplifiers or tape decks directly above or below this unit. Because this amplifier has a high power density, it has a strong magnetic field which can induce hum into unshielded devices that are located nearby.

This field is strongest just above and below the unit. If an equipment rack is used, we recommend locating the amplifier(s) at the bottom of the rack and the preamplifier or other sensitive equipment at the top.

The lightning bolt triangle is used alert the user to the risk of electric shock

The exclamation point triangle is used to alert the user to important operating and/or maintenance instructions.

Precautions

Although your amplifier is protected from external faults, the following safety precautions are recommended:

1. Do not change the position of the bridge mode switch, parallel switch or 25Hz Hi pass filters until

the input levels have been turned down.

2. There are important differences between Stereo, Parallel and Bridge mode operation. Please refer to page

8 for a detailed description of the different modes and there uses.

3. Switch off the amplifier or turn down the inputs before connecting to the in/out XLR's.

4. Do not short the ground lead of an output cable to the input signal ground. This will form a ground loop

and may cause oscillations.

5. Do not connect both channels positive outputs together in parallel or stereo modes. And never connect any

channels positive output to chassis ground.

6. When using the amplifer with 2 ohm loads the 16 Amp CEE Form connector must be replaced with a 32

AMP CEE Form connector.

7. Do not operate the amplifier from AC mains in excess of 10% variation above or below the selected line

voltage, and only at the specified line frequency.

2.Standby LED

on.

3.Level Controls

Used to control CH 1 & 2's output levels.

4.Power LED's

The Power LED's indicate that each channel is active.

5.Signal LED's

When illuminated the LEDs indicate an audio signal is present at the channel's

output.

6.'CEP' LED's (L)

The CEP LED's indicate the Clip Elimination circuit is active. The CEP circuit

works by examining the audio output signal, it then regulates many circuits

within the amplifier to eliminate all traces of clipping at the output. As a clipped

waveform cannot be generated within the amplifier, careful monitoring of the

input level is not necessary. Under normal working conditions the CEP LED's

should be illuminated around 50% to 80% of the time. Note that the CEP circuit

can only prevent a clipped waveform from be generated within the amplifier

itself, it cannot remove a clipped waveform that has been produced from a

component earlier in the chain.

7.Protect LED's (P)

The protect LED's light up when the amplifier detects speaker over excursion,

dangerous subsonic frequencies, DC or thermal overload. Note the protect LED's

also indicate the soft start circuit is active, so will illuminate during power on.

See page 8 for more details about the VSP protection circuit.

8.Current Draw Display

The LED readout displays the average RMS current being draw by the amplifier.

As the value displayed is an averaged reading, peaks values will be higher than

indicated. The readout is displayed in Amps (A) and values less than 0.8 Amps

are not displayed. During switch on the meter will read 50 Amps, this is for

calibration purposes and is not an indication of the current required during

switch on.

Notes

Bridge Mode

Connect to input 1 only and use the two CH1 speakon outputs or both + binding posts.

Use +1 for signal + and +2 for signal - Minimum impedance in bridge mode must be 4 ohms, i.e. one 8 ohm load from each speakon. The amplifier is mono when running in bridge mode and both CH1 speakons output the same signal. When using the binding posts for bridge mode, CH 1 + terminal is signal + and CH2 + terminal is signal -

Parallel Switch

Input 1 is linked to input 2. Connect to input 1 or input 2, the same signal will output from both CH1 and CH2 outputs. Each channels level is set with its own level control.

Note that parallel operation on Infinite amplifiers is not like the parallel mode on some amplifiers that allow you to drive into very low impedances. Parallel mode on Infinite series amplifiers makes both inputs receive the same signal.

VSP Velocity Sense Protection

All version 2 Infinite amplifiers are equipped with velocity sensing protection.

The VSP circuit monitors back EMF and will attenuate the output for a very brief period if the amplifier detects over excursion or potential damage to a speaker.

If very severe overload conditions are detected and speaker failure is imminent, the amplifier will mute its output for a brief period. Reducing the amplifiers output level will stop the protection circuit from muting the output in this situation.

Please note that the VSP circuit can only assist with protecting your speakers.

It in no way guarantees complete protection against any component failure and safe working practices should always be followed with regard to matching amplifier output levels to speaker input ratings.

Onboard Filter Network

The onboard filter network allows both Hi and Lo pass filters to be set on individual channels. A typical arrangement might be to set a Lo pass filter on channel 1 and use it to drive bass speakers and to set a Hi pass filter on channel 2 and use it to drive midtop speakers. The frequency select switch would be used to set the crossover frequency in this case. The crossover frequency can be 90Hz, 120Hz or 160Hz.

Both Hi and Lo sections of the crossover are also output from the 4 rear panel jack sockets, permitting the onboard crossover to feed other amplifiers in the system. The Hi outputs are from the Hi Pass section and the Lo outputs are from Lo Pass section. This allows for the amplifier with the crossover to drive bass speakers and other amplifiers to drive midtop speakers, or vice versa. Note that the crossover outs, output both Lo and Hi crossover sections irrespective of what the amplifiers channel filters are set to.
