.
A Series amplifiers draw in air at the back and expel it at the front: keep front & back of unit free of obstruction.
The amplifier may be used free-standing or installed in a 19" rack. If installed in a rack, the rear of
the chassis should be supported. Rear rack-mount supports are integral on all models except the A500 & A700v.
The amplifier is factory set to your local supply voltage
WARNING: THE VOLTAGE SHOULD ONLY BE CHANGED BY AN AUTHORISED CHEVIN DEALER
The A500 & A700v connect to the mains supply via a detachable power cable with integral connector (supplied).
All other models connect to the mains supply via a fixed power cable, colour coded to European standard:
Green/Yellow = Earth Blue=Neutral Brown= Live
N.B.
The live connector in certain 115V models is coloured RED.
The amp must be connected to a 3-pin grounded outlet via a 3-pin connector of sufficient voltage
and current rating. If the connector has provision for a fuse, a suitable fuse must be fitted.
The A5000, A6000 and Q900 have 2 power cables
WARNING: ALL CHEVIN AMPLIFIERS MUST BE EARTHED
The power rating of the supply should be at least twice the total audio output of the system.
ELECTRIC SHOCK/FIRE HAZARD: The unit must be connected to an adequately rated grounded
outlet. All cables, switch gear et al must be adequately rated to avoid risk of overheating & fire
.
The neutral current will not balance on three-phase systems.
Use individual neutral connections from each phase outlet back to the distribution point.
Alternatively, ensure the neutral conductor is of sufficient capacity to handle a return current
equal to the sum total of the current in the three phases.
All amplifiers are fitted with XLR connectors on the inputs.
All inputs are electronically balanced and can accept signal from balanced & unbalanced sources.
A500 and A700v
: One female XLR connector on the input of each channel.
A750, A1000, A1004, A1500, A2000, A3000, A4000, A5000, A5003, A6000, Q900:
One male & one female XLR connector on the input of each channel. These connectors are wired in parallel.
Q6, Q1004 & QB1000/600:
One female XLR connector on the input of each channel.
N.B. The amps are not mixing amplifiers: do not directly connect any channel to more than 1 signal source.
Maintain the same phase polarity on all equipment in signal chain.
PIN WIRING - MALE & FEMALE XLR INPUT SOCKETS
PIN 1: GROUND, connects directly to chassis PIN 2: HOT (+) PIN 3: COLD(-)
CONNECTION TO BALANCED SOURCES
1.
Fit XLR connectors at both ends of the cable.
2.
PIN 1 connects via the cable braid (screen). Always connect the screen at both ends of the cable.
3.
PINS 2 & 3 connect via the two signal wires of the cable.
CONNECTION TO UNBALANCED SOURCES
1
. At the SOURCE END of the cable, the cable screen & cold (-) signal wire connect to the chassis of the
source equipment via the sleeve of the jack plug/phono connector/PIN 1 of the XLR-type plug.
2.
The signal carrying conductor (which connects to PIN 2 of the XLR at the amp end) connects to the
HOT output terminal of the source equipment via the jack plug tip/phono connector pin/signal-carrying XLR pin
