A precision input LEVEL attenuator is used to adjust the volume levels. To deliver the

amps maximum power without reducing the headroom of the signal source, the level

controls should be turned full on. For multi-speaker systems, the volume levels can be

used to match loudspeakers with different output sensitivity levels and room locations.

5. CHANNEL SIGNAL INDICATOR, 40% & 80% OUTPUT

You have a 3 meter segment per channel to indicate levels. The green SIGNAL LED

indicator will start to flash when there is a low input signal (-30dBµ). The 40% and 80%

LED’s will light solid when output power has reached 40% and 80% levelsof full power.

6. CHANNEL CLIP INDICATOR

The RED CLIP LED indicators flash when each channel has reached its maximum

output. Occasional flashing caused by low frequency peaks are difficult to prevent and

will not harm speakers capable to handle the amplifiers output. However, consistent

flashing (excessive clipping/square wave) will damage speakers if not reduced. This

does not cause damage to the amp.

7. COOLING VENTS/FAN

Upon rack installation, the rear of the amp must be fully exposed to room temperature

air. The surrounding air should not be warmer than 120° with full loading and heavy

usage, or the thermal protection could active early. The front cooling vents are not to

be restricted. Air flows from back to front. The use of external fans need to flow the

same direction or the amplifier will starve for air and may thermal off.

within 3 minutes. The PROTECT LED will turn off when ready. Check for the

following conditions; a) The rear intake air is not restricted, b) The intake air

is not extremely warm, c) The front exhaust vents are not restricted, or d) No

than one connected to each channel).

the amp on for the fan to cool the amp down. The amp will automatically reset

3) Overheating is usually determined when the amp stops in the middle of a system. When the short is removed the amplifier will resume operation. Check

for shorted cables and that the total speaker impedance is not below 2 ohms per

13. SPEAKER BINDING POSTS

For wire (banana connectors), use the rear BINDING POSTS to connect your speakers.

Wire sizes up to 7 gauge (50 amps) can be inserted into the binding post “side holes”.

Larger cable can be used with “banana” plugs which plug into the end of the binding posts.

Binding posts are spaced on ISO standards.

For BRIDGE speaker connections (see 11 BRIDGE MODE).

14. AC POWER Your amp is designed to auto switch to either 120V 60 Hz or 240V

50Hz. The voltage range for 120V is 95V to 132V and for 240V is 195V to 255V. The rear

heavy-duty AC receptacle will accept a universal grounded AC cord. Be sure to check

your power source before plugging into a grounded (3 prong) outlet. Firmly push the

AC cord all the way into the receptacle or the amp will not function. WARNING: Never

used, except for parallel to another amplifier (see 9 PARALLEL). The minimum speaker

REAR PANEL

8. CHANNEL INPUTS

The XLR balanced inputs will help reduce signal interference and allow longer cable

runs from your signal source (mixer, etc). Because this is a balanced input, the gain

will be 6 dB higher than using an unbalanced 1/4” cable on the 1/4” TRS input jacks.

XLR pin configuration: Pin 1: Ground, Pin 2: positive balanced signal, Pin 3: negative

balanced signal.

The 1/4” TRS jacks are balanced and designed to receive unbalanced input signals.

Balanced signals coming into these jacks should be wired with the connector’s tip

going to signal + and the connector’s ring to signal -. The connector’s sleeve is tied

internally to ground.

9. PARALLEL “Y” INPUTS

The rear PARALLEL switch connects both channels together from either input. This

eliminates Y adapter cables. This feature is used to “daisy chain” one piece of equip-

ment to another. Just plug into the unused INPUT (TRS or XLR) and it will become the

output for other equipment.

10. 100Hz LOW PASS FILTER SWITCHES

Each channel has a third order (18DB/oct)100Hz Low pass filter subwoofer crossover.

This makes it easy to add subwoofers to your system. In Bridge mode the channel

one low pass filter can still be used for full amplfiier power into a single bridged sub.

11. BRIDGE MODE

With your amplifier off, push “in” the rear (recessed) BRIDGE switch then make your

connections to the RED binding posts (ch 1 is + and ch 2 is-). In bridged mode, the

amplifier channels are out-of-phase from each other. Accidental pressing of the switch

will not cause damage, but the outputs will be out of phase and channel 2 input will

take in signal. WARNING: No other speaker connectors or binding posts may be used

destroy most speakers.

12. SPEAKER 1/4” AND SPEAKON™ COMBO OUTPUTS

power applications and Speakon™ connectors for high power application. Secure the
