Carvin DCM150 User Manual

CARVIN ENGINEERING DATA OPERATING MANUAL

The DCM150 professional amp is designed utilizing Carvin’s years of expe­rience in power amp technology. It meets and exceeds every standard for
professional amplification. The thick brushed anodized aluminum face plate,
large recessed knobs and heavy-duty aluminum chassis reflect the manu­facturing quality within. The DCM150 “High Energy Transfer” amp carrys
the CE approval for world-wide use.

PURE—TRANSPARENT SOUND

Carvin considers the sound of an amp equally important as its reliability.
To insure pure, uncolored sound, we designed one of the fastest respond­ing power amps on the market today. High slew rates deliver superb tran­sient response. High frequencies are transparent and open—even at high
levels. Linear feedback circuits reduce distortion to near the theoretical zero
limit preventing any type of harshness which would lead to ear fatigue. The
DCM150 amp delivers flat, transparent, unaltered sound—especially impor­tant to the studio user . These amps are designed to deliver non-stop, con­tinuous power and are completely protected from heat and short circuits.

ULTRA RUGGED FOR TOURING

Every chassis is made from heavy-duty 16 gauge aluminum that is light­weight and prevents rust. All internal cabling is neatly tied and harnessed.
Heavy-duty power switches, recessed knobs & machined aluminum front
panels all give the DCM amps a “tank-like” ability to handle rough, tour­ing transport.

TOTALLY MODULAR

With the DCM150, Carvin brings you totally modular construction. If
you ever need an I/O (input/output) connector card because a connector
wore-out, just unplug it and re-install the replacement card in minutes.
You don’t have to de-solder anything. This applies to every aspect of the
DCM150 amp including the power supply, power cards, and heat sinks.
Everything is connected by heavy-duty connectors for easy replace­ment—even the Toroid transformer is a total plug-in.

LOSE THE WEIGHT...NOT THE PERFORMANCE

For some companies, weight reduction means cost reduction. Carvin how­ever , uses expensive TOROID transformers to reduce weight. T oroids deliver
extra amounts of “on demand” current for continuous operation. This gives
the power supply a solid foundation, yielding more headroom. Not only do
toroids deliver high current, but they are known for reducing stray magnetic
fields eliminating hum & noise. This is especially important for the record­ing industry.

and comments to us.

FRONT PANEL

1. MOUNTING

The rack mounting holes are designed on ISO standard spacing. Four
10-32 x .5” phillip machine screws are normally used to secure the amp.
Rear support brackets are not required.

2. POWER SWITCH

Check 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. This color was chosen so
the operator could see the red protect indicator from a distance.

3. CHANNEL LEVEL CONTROL

A precision input LEVEL attenuator is used to adjust the volume levels.
To deliver the amps full power without reducing headroom of the signal
source, the level controls should be turned up full.

4. CHANNEL SIGNAL INDICATOR

The green SIGNAL LED indicators will start to flash when there is a signal
passing to your speakers (-30dBM). This lets you know when the amp is
passing a signal to your speakers.

5. CHANNEL CLIP INDICATOR

The red CLIP LED indicators will start to flash when each channel has reached
its maximum output. Occasional flashing caused by lower bass frequencies
is OK. However, consistent flashing caused from higher frequencies may
damage high frequency drivers (excessive distortion). This does not cause
damage to the amp.

6. EQ EXPAND SWITCH

When set to the ‘in’ position this circuit will cut the mids by -4dB at 1KHz.
This works well as a loudness contour when operating at low volume levels
or adds tone when using it in a bass or guitar rack. When set to the ‘out’
position it provides a flat, normal response. Try it both ways and set as
desired.

REAR PANEL

7. XLR CHANNEL INPUTS

For most professional applications, use the XLR balanced input. This
will help to reduce hum and allow of longer cable runs from your signal
source (mixer, etc). Because this is a balanced input, the gain will be 6
dB higher than using a non balanced 1/4” input. XLR pin configuration:
Pin 1: Grounded through the GROUND LIFT switch, Pin 2: positive Bal.
signal and Pin 3: negative Bal. signal.

8. CHANNEL 1/4” PHONE JACK INPUT

These 1/4” TRS phone jacks are designed to receive either balanced or
unbalanced input signals. Balanced signals coming into this jacks should
be wired with the connector’s tip going to signal + and the connector’ s ring

to signal –. The connector’s sleeve is then tied to ground through the GROUND
LIFT switch–.

9. SPEAKER OUTPUTS

The standard 1/4” SPEAKER jacks are used for most applications. T urn

the amp off before connecting your speakers.

10. SPEAKER BINDING POSTS

For heavy-duty 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 posts “side holes”. Larger cable can be used with “banana”
plugs which plug into the ends of the binding post (remove colored caps).
Binding posts are spaced on ISO standards. Use the two center RED bind­ing posts for BRIDGE speaker connections (see 11 BRIDGE MODE).

11. BRIDGE MODE—70V DISTRIBUTION SYSTEMS

The DCM150 can be operated in bridge mode if you require a 70V dis­tribution speaker system or a high powered mono (single channel) amp.
With your amp off, push in the rear BRIDGE switch after you have made
your speaker connections to the rear center RED binding posts (ch 1 is
+ and ch 2 is -). No other speaker jack or binding post can to be used at
the same time!”. The INPUT and LEVEL is handled by channel 1. Channel
2 is non-operational. The minimum speaker impedance is 8 ohms. CAU­TION: The power developed by bridging your amp can destroy speakers!

12. PARALLEL OR “Y” INPUTS

The rear PARALLEL switch allows you to drive both channels from either
input. All signals entering any input will be available on both channels.
This eliminates Y adapter cables. This feature is used to “daisy chain”
one piece of equipment to another . Just plug into the unused INPUT (1/4”
or XLR) and it will become an output for other equipment.

13. INPUT GROUND LIFT

Many times sound systems are connected in such a manner to cause a
grounded loop with the inputs that result in audible hum. The input GND
LIFT (1/4” & XLR) switch on the rear panel will help eliminate this prob­lem. If not, another way to eliminate ground loops is to install a “line match­ing” transformer between the amplifier input and the signal source and
cut the ground wire to PIN 1.

14. AC POWER

Your amp is designed to run on either 120V 60 Hz. The voltage range
for 120V is 95V to 132V . The rear heavy-duty AC cord is designed for 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!

CONNECTING THE SYSTEM

The following diagrams illustrate typical connections. Although these illustrations show
XLR’s for inputs and 1/4” plugs for outputs, a variety of alternative connectors are available.
For most stage setups, mono (not stereo) is recomended. The reason for this is the audi­ence on the left will not hear the same program material on the right if the program is done
in true stereo.

INPUT CONNECTIONS

The preferred method of connecting input signals is with balanced XLR’s (two conductors
plus a shield wire such as Carvin professional XLR cables). Balanced input signals provide
the highest gain and best noise rejection. 1/4” stereo cables are also capable of providing
balanced input by using a stereo plug (tip-positive, ring-negative & sleeve-ground). Not all
sources provide balanced outputs. If this is the case, standard 1/4” input cables work fine
with cable lengths under 25 feet (single conductor plus shield) providing there is no ground
loop in the system.

SPEAKER CONNECTIONS

There are two 1/4” speaker jacks available for speaker connections (one for each channel).
Additionally, there are two pairs of binding posts that not only allow for high current con­nections to speakers but are also used for “bridging” the amps output (see rear panel sec­tion 14 & 15). Use heavy gauge wire for all speaker connections (no lighter than 16 gauge
up to 50’, Carvin’s PH50). Caution: Never use shielded cable (microphone or instrument
input cable) to connect speakers. These cables will not handle the required current and may
cause your amplifier to oscilate because of the internal shield.

HELP SECTION

1) WILL NOT TURN ON

Check the power to the unit. Check for tripped circuit breakers, unplugged extension cords or
power-strip switches that may be turned off. Check the fuse. If a dark brownish color or no wire
can be seen within the glass fuse, then replace. The unit may be perfectly fine but occasionally
the fuse may blow because of high AC voltage surges. After the fuse has been replaced with the
proper value and if the fuse fails again, the product will require servicing (be sure to use a slow
blow fuse if required). Check your input and speaker output cables.

2) MAINTAINING YOUR EQUIPMENT

Avoid spilling liquids or allowing any other foreign matter inside the unit. The panel of your unit can
be wiped from time to time with a dry or slightly damp cloth in order to remove dust and bring back
the new look.

As with all pro gear, avoid prolonged use in caustic environments (salt air). When

used in such an environment, be sure the amplifier is adequately protected by rack, covers, etc..
