MATRIX ELEMENTS GT800FX POWER AMPLIFIER

Matrix amplifiers are the result of many decades of experience in the design of exceptionally robust and reliable amplifiers. They are designed to breathe life into your sound, by controlling your speakers with exacting authority through the uncompromising delivery of clean, undistorted power, from a package which is smaller and lighter than you might expect for the performance it delivers.

SPECIFICATIONS:

Front And Rear Panel Layouts: 1U & 2U MODELS

- Power Switch : This switch controls the power supply to the amplifier.

- Indicator Section, Status:

a. Power Indicator : This indicator shows when the amplifier is on and is receiving power.

b. Parallel Mono Mode Indicator : This indicator shows if (parallel) MONO mode is selected on the rear panel. For channel pair A and B only Input A will be used to drive both channels. Full independent level control of the amplifier output stages is still possible via the Gaincontrols.

c. Bridged Mono Mode Indicator : This indicator shows if Bridged mode is selected on the rear panel. It is mostimportant that this indicator is not illuminated unless bridged mode is required. This is because when bridged mode is selected, Channel A will be out of phase with Channel B. This will result in poor bass response and an uns at is factory sound if left and right outputs are used. In this mode Channel A controls the output level.

d. Protect Indicator : This indicator lights briefly during the power up cycle and also lights should a fault occur. Illumination of the protect indicator, shows that the output of the amplifier has been disconnected by means of an internal relay to protect connected speaker systems from being damaged by the fault.

- Gain Controls : The level of each Channel is individually adjusted by these controls. Rotating these controls fully clockwise, results in no attenuation to the incoming audiosignals.

- Indicator Section, Signal levels : These show the (Peak) output level of the amplifier for each channel, in both Stereo and Mono modes. These will start to illuminate when a signal is present at the speaker sockets when driven above a threshold of approximately -9db. Note that for levels below this amount the led may not illuminate. The signal level lights are useful in indicating how much power is being sent to the speaker connected. The -9db threshold relates to approximately 12.5% of the amps available power at the load it is connected to. The table below gives the ratings at -9db for typical impedances connected.

- Cooling Fan Outlets : Hot air exits here. Make sure all rear (and front) ventilation paths are free from obstruction and air flows freely, otherwise the amplifier will trip into thermal protect mode prematurely and in some extreme circumstances damage may occur.

- Output Connectors : The Output sockets are Neutrik Speakon / 1/4" combi connectors. They accept both Neutrik NL2FC & 1/4" jack plugs (NL4FC accepted, however only terminal pair 1 carry signals). Avoid inferior alternatives, as they may present numerous hazards due to less than ideal construction.

- Input Signal Sockets : These are Neutrik combined female XLR and 1/4" jack sockets. For cable runs of under 12", (ie. within a rack system) standard good quality instrument leads should provide a similar level of RF shielding to XLR cables. For longer cables runs, balanced cables (XLRs) are recommended.

- Output Mode Selector : STEREO, MONO or BRIDGED (mono) Output can be selected using this switch. Take care to ensure the correct mode for your application is selected:

In Stereo mode, channels A and B operate independently, when fed with separate input signals. (Think of this as two separate mono amps fed by their own input.)

In Parallel (Mono) mode, Input A is connected to feed both amplifier channel A and B. Input B is not used. Full independent level control over each amplifier output channel remains possible. (This is useful if you want to send the same mono signal to two separate cabs)

In Bridged (Mono) mode, the input from channel A is fed out of phase to channel B and combined to give a higher power mono output

- Power Connection : Mains power is supplied to the amplifier by a standard 10 Amp IEC mains socket.
