FRONT PANEL 1. MOUNTINGSturdy one piece 12 gauge steel face plate accommodates standard 19 rack installation. The rack mount-
ing holes are designed on ISO standard spacing. Four 10-32 x .5 phillips machine screws are normally
used to secure the amp. Rear support brackets are not required. 2. POWER SWITCHCheck the power amp connections and verify the AC line power source before engaging the POWER
switch. The yellow LED unmistakably indicates that all circuits are properly powered up. Yellow is used
so the operator can see the red indicators (clipping or protect) from a distance. 3. CHANNEL LEVEL CONTROLA precision input LEVEL attenuate 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. 4. CHANNEL SIGNAL INDICATORThe green SIGNAL LED indicators will start to flash when there is a low signal passing to your speak-
ers (-30dBΒ΅). This lets you know when the amp is passing a signal to your speaker connectors. 5. CHANNEL CLIP INDICATORThe red CLIP LED indicators flash when each channel has reached its maximum output. Occasional
flashing caused by low frequencies is OK. However, consistent flashing caused by higher frequencies
may damage high frequency drivers (excessive distortion). This does not cause damage to the amp. 6. COOLING VENTS/FANUpon rack installation, the rear of the amp must be fully exposed to room temperature air. The sur-
rounding air should not be warmer than 120Β° or the thermal protection could active the PROTECT LED.
The front cooling vents are not to be restricted. 7. PROTECT LED INDICATOR The red PROTECT LED provides the operator with information about the status of the amplifier. The
PROTECT LED can come on under 3 different conditions (when this happens, both channels are muted
and the speaker relays disconnect the speakers);
1) During power-up, the amplifier stays in a muted state for approx. 3 sec until it determines that
everything is functioning normally (no output shorts or over temp conditions).
2) When the output load draws excessive current or a direct short is detected caused by a shorted
speaker cable or speaker system, the RED PROTECT LED will illuminate. Reset this condition by
turning the amp off for two seconds and then on again.
Check for shorted cables and that the total
speaker impedance is not below 2 ohms per channel (4 ohms bridged).
3) Overheating is usually determined when the amp stops in the middle of a performance and the
PROTECT LED comes on. If this is the cause, leave the amp on for the fan to cool the amp down.
The amp will automatically reset 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 excessive speaker load (try
other speakers or remove speakers if you have more than one connected to each channel).
REAR PANEL 8. XLR CHANNEL INPUTSFor most applications, use the XLR balanced inputs. This will help to reduce hum 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 the 1/4 input jack with non balanced lines. XLR pin configuration: Pin 1: Grounded
through the GROUND LIFT switch, Pin 2: positive Bal. signal and Pin 3: negative Bal. signal.
9. CHANNEL 1/4 TRS INPUTThis TRS jack is designed to receive either balanced or unbalanced input signals. Balanced signals
coming into this jack should be wired with the connectors tip going to signal + and the connectors ring
to signal -. The connectors sleeve is then tied internally to ground through the GROUND LIFT switch. 10. PARALLEL OR Y INPUTSThe 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 equipment to another. Just plug into the unused
INPUT (TRS or XLR) and it will become the output for other equipment. 11. INPUT GROUND LIFTMany times sound systems are connected in such a manner as to cause a grounded loop with the inputs
which results in audible hum. The input GND LIFT switch (TRS & XLR) on the rear panel will help elimi-
nate this problem. If not, install a Carvins MTF55 Ground lifter between the amplifier input and the signal. 12. LIMITERSTo activate the LIMITERS, engage the rear limiter switch. The built-in Optio limiters are recommended
to hold down peaks that could cause distortion. To check the effectiveness of the limiters when the chan-
nel starts to distort (under full output), engage the limiters and listen for the reduction of the distortion.
If the distortion stops, you can try to turn the channel up for more power until distortion is heard. The
lower bass frequencies are most affected. WARNING: Do not check in an environment where the sound
level could damage your ears! 13. SPEAKER 1/4 AND SPEAKON-’ OUTPUTS The standard 1/4 SPEAKER jacks are offered for low power applications. Speakon-’ connectors are
provided for high power application. Secure the Speakon-’ connection by turning to the right. The center
Speakon-’ is for the Bridge output only. Turn the amp off before connecting your speakers. 14. SPEAKER BINDING POSTSFor high power speaker connections, 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 (remove colored caps from end of binding
posts). Binding posts are spaced on ISO standards. Use the two center RED binding posts to BRIDGE
speaker connections (see 15 BRIDGE MODE). 15. BRIDGE MODE-
25V/70V DISTRIBUTION SYSTEMS
The DCMs can be operated in bridge mode if you require a 25V / 70V mono distribution speaker system
or a mono (single channel) amp, which doubles the power into a single load. With your amp off, push
IN the rear (recessed) BRIDGE switch after you have made your connections to either the center bridge
Speakon-’ or the rear center RED binding posts (ch 1 is + and ch 2 is -). Carefully select or damage may
result to the speakers (this is why the switch has been recessed). No other speaker connectors or bind-
ing posts can be used at the same time! The INPUT connector and LEVEL is handled by channel 1. Channel
2 is non-operational. The minimum speaker impedance is 4 ohms. CAUTION: The power developed by
bridging your amp can destroy most speakers. 16. AC POWERYour amp is designed to run on either 120V 60 Hz or 240V 50Hz depending on the model purchased.
The voltage range for 120V model is 95V to 132V and for 240V model it is 195V to 255V. The rear heavy-
duty AC receptacle will accept a universal grounded AC cord that is designed your country. Be sure to
check your power source before plugging into a grounded (3 prong) outlet. Never defeat the grounded connection or electrocution may result!
Firmly push the AC cord all the way into the receptacle.
FUSE:The fuse is located within the main chassis above the AC connector mounted on the rear, inside
the PC card. Normaly if the fuse fails, the amp will require service. See spec. chart for fuse values.
NOTE: Each amp will require a dedicated circuit if you are driving the amp to its full output. There will
be a sustained loss of power if the AC voltage falls below the rated 120V or 230/240V. Use a heavy gauge
power cable and power source.

6) DEDICATED CIRCUIT BREAKER: Each amp will require a
dedicated circuit breaker for its full output. There will be a
sustained loss of power if the AC voltage falls below the rated
120V or 230/240V input. 1) NO SOUND FROM CH 2: The rear (recessed) BRIDGE
switch has been inadvertently pushed in.
2) STEREO CHANNELS SOUND THE SAME: The rear
PARALLEL switch has been inadvertently pushed in.
3) NO HIGH FREQUENCIES: Tweeters or midrange drivers have
been damaged or blown from feedback or to much power.4) SYSTEM HUM: Switch the rear GND LIFT switch IN or OUT. If
the hum is not eliminated, then install Carvins MTF55 Ground
Lifter between the amplifier input and signal source. This iso-
lates the input ground from the AC power ground.
5) POOR SOUND (BASS): The speaker systems are wired out
of phase to each other. To correct, reverse the wires on one
speaker connector only and your sound, especially the bass
response will improve.PROTECT-50 30 22 19171513121110
