Detachable power cable with IEC connector. • Warranty card. Please complete this card and return it to Chevin Research. Failure to register may result in delays if you require warranty service. See rear cover for warranty. Positioning • Your amplifier must have good ventilation. Air is drawn in at the rear panel and is expelled at the front. It is vital to keep front and rear of unit free from obstruction. • Your 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. Power Wiring • EARTHING: All Chevin amplifiers must be earthed. • A500 & A700v models connect to the mains supply via a supplied detachable power cable. • All other models have fixed power cables, colour coded to European standards: Green/Yellow = Earth Blue=Neutral Brown= Live • The A5000, A6000 and Q900 have 2 power cables. • The live connector in certain 115V models is coloured RED. • The amplifier 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. Mains supply • The power rating of the supply should be at least twice the total audio output of the system. • VOLTAGE SELECTION: Your amplifier is factory set to your local supply voltage and should be changed only by an authorised Chevin dealer. • ELECTRIC SHOCK/FIRE HAZARD: The unit must be connected to an adequately rated grounded outlet. All related cables, connectors and switch gear must be sufficiently rated to avoid risk of overheating and fire. 2 Power (continued) Three phase systems • IMPORTANT: 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. Inputs • XLR connectors are used on all amplifier inputs except for Line250 and Line500 models. • Do not directly connect any channel to more than one signal source, these are not mixing amplifiers. • All inputs are electronically balanced and can accept signals from balanced and unbalanced sources. Maintain the same phase polarity on all equipment in the signal chain. Inputs from balanced sources Use shielded cable with XLR connectors at both ends (except Line250 and Line500): • Ground/screen: Connect cable braid to XLR pin 1. • HOT (+) signal: XLR pin 2 • COLD (–) signal: XLR pin 3 Inputs from unbalanced sources Use shielded cable with an XLR connector at the amplifier end (except Line250 and Line500) and either a jack plug, phono plug or XLR connector, as appropriate: • Ground/screen and COLD (–): At the source end, connect the COLD signal wire and cable braid to the sleeve of jack plug or phono connector, or pin 1 of an XLR connector (if used). • At the source end of the cable, connect the HOT (+) signal to the tip of the jack plug, the pin of the phono plug or pin 2 of an XLR connector (if used). • Connect the XLR at the amplifier end as per ‘Inputs from balanced sources’ above. Inputs to Line250 and Line500 models The Line250 and Line500 models use block connectors at the rear panel. Use connections at the source end as explained above for balanced or unbalanced sources. At the amplifier end, make wire connections rather than using an XLR connector. Mono bridging Various models can have their channels bridged together (except A700v, A5000, A6000, QB1000/600, Line250 or Line500). For details about the necessary wiring, see page 6. Speakon is a registered trademark of Neutrik AG XLR is a registered trademark of ITT Cannon Ltd. 3 Outputs Connections are made to the amplifier load using Neutrik Speakon sockets (except for Line250 and Line500 models). As with input connectors, maintain phase polarity throughout the system. IMPORTANT: High voltages are present at output terminals during operation and for a period afterwards. Do not connect the amplifier to any other amplifier output or to any equipment other than a speaker system. Take great care to note the wiring specifications particular to your amplifier model: A700v One Speakon socket per channel, wired as follows: 1+ = HOT 1– = COLD (not Ground) 2+ = NO CONNECTION 2– = NO CONNECTION WARNING: The A700v output is permanently connected in bridge mode. Both hot and cold outputs carry high level signal. Further bridging is impossible. No terminal of the speaker socket is connected to ground. Do not connect any part of the speaker system to ground.

Consult an authorised Chevin dealer to enable this feature. 5 Mono bridge mode WARNING: You cannot bridge the A700v, A5000, A6000, QB1000/600, Line250 or Line500. Inputs A500 1 Make a lead from the source with two XLR plugs at the amplifier end. 2 HOT output from the source goes to pin 2 of Channel A XLR and pin 3 of Channel B XLR. 3 COLD output from the source goes to pin 3 of Channel A XLR and pin 2 of Channel B XLR. 4 The cable screen goes to pin 1 of both XLR plugs. Q6 • Q1004 1 Make two leads, one for each source channel. Each lead needs 2 XLR plugs at the amplifier end. 2 In each lead, HOT output from the source goes to pin 2 of the first XLR & pin 3 of the second XLR. 3 In each lead, COLD output from the source goes to pin 3 of first XLR & pin 2 of second XLR. 4 The cable screen goes to pin 1 of both XLR plugs. 5 In each lead, first XLR goes to INPUT A (INPUT C) and second XLR goes to INPUT B (INPUT D). A750 • A1000 • A1004 • A1500 • A2000 • A3000 • A4000 • A5003 • Q900 1 Bring the input signal into channel A as usual. 2 Make a lead with an inline XLR socket to go to the Channel A LINK connector and an XLR plug to go to the Channel B INPUT socket. 3 Connect socket pin 2 to plug pin 3 and similarly, socket pin 3 to plug pin 2. Q900: Make a second lead as above for channels C & D. Outputs A500 • A750 • A1000 • A1004 • A1500 • A2000 • A3000 • A4000 • A5003 • Q900 1 Split the speaker cable by separating the two conductors for a distance of 20cm along cable. 2 Connect the red conductor to terminal 1+ of the Channel A Speakon connector. 3 Connect the black connector to terminal 1+ of the Channel B Speakon connector. Do not make connections to any other terminals. Q900: Repeat the above for channels C & D. Q6 • Q1004 1 Connect the red conductor of the speaker cable to terminal 1+ of channel A (C) Speakon conn. 2 Connect the black conductor of the speaker cable to terminal 2+ of channel B (D) Speakon conn. WARNING: Do not make connections to terminals 1– or 2–. Operation Set the gain controls of both channels in the same position (preferably at maximum), and control the gain from elsewhere in the system. This ensures the load is shared equally between channels. Loading and power output Please see the rear page for mono bridge loading and power output values. 6 Operation & Servicing Switching on 1 Turn the gain controls to the minimum positions. 2 Connect the unit to a mains supply of sufficient power and click the front panel switch(es) to the ON position. Depending on the internal temperature, the fans may run. • The green Power indicators will illuminate. • The red Clip indicators will illuminate if overdriving is imminent. WARNING: Keep sound levels down. High levels of sound can damage hearing. Switching off • Turn the gain control(s) to the minimum position(s). Click the front panel switch(es) to the OFF position and disconnect from the mains supply. WARNING: High voltages are present at output terminals for a period after switching off. Protection systems • Mains power supply failure: When power is restored, the amp will AutoMute for five seconds. Do not increase gain settings during this period. Note: A500, A700v, Line250 and Line500 do not AutoMute. • Shorted output: The unit can operate indefinitely into a shorted output. Normal operation will resume upon removal of the short circuit. • Low load impedance: Protection is immediate. • Clipping: The affected channel’s red Clip indicator will illuminate shortly before clipping. A further increase in signal level will activate the SoftClip circuit. • RF, DC or very low frequency signal at output: A self resetting circuit will activate to protect the load. • Cooling systems: The internal fans react to both high signal level and temperature inside the unit. If the ambient temperature is high, fan speed will increase even in the absence of a signal. Servicing WARNING: All servicing and internal maintenance must be referred to an authorised Chevin dealer. Chevin Research accepts no responsibility or liability relating to injury or damages suffered as a result of misuse or unauthorised tampering with amplifiers. • Do not remove any covers or touch any internal parts. Do not allow any objects (e.g. screwdrivers, cable ends, etc.) to enter the unit. • If the unit of any other electrical equipment in the system becomes wet during operation, disconnect the power source immediately. Do not touch the amplifier. Consult a qualified engineer. • If there are any signs of mechanical damage, disconnect the power source and consult a qualified engineer. 7 A500 SEE PAGE 6 FOR OPERATION DETAILS • FRONT PANEL POWER SIGNAL CLIP CHANNEL A A500 LINEAR AMPLIFIER Channel A gain control POWER CHANNEL B Power, Clip and Signal indicators Channel B gain control A700v Power switch SEE PAGE 6 FOR OPERATION DETAILS • FRONT PANEL POWER SIGNAL CLIP POWER GAIN A700v LINEAR AMPLIFIER Power, Clip and Signal indicators Q1004 Q1004 • QB1000/600 POWER 1 QB1000/600 CLIP SIGNAL 0 INF CHANNEL B CHANNEL A 10 00 600 POWER 1 20 CLIP SIGNAL 0 INF ATTENUATION dB 600W Power, Clip and Signal indicators 0 INF INF ATTENUATION dB CHANNEL D ATTENUATION dB 1000W 1000W (Channel B) gain control Channel D gain control 6 3 POWER 1 20 0 INF ATTENUATION dB 1000W 1000W (Channel C) gain control Power switch CHANNEL D 6 1 20 0 Power, Clip and Signal indicators 10 POWER 1 20 CHANNEL C Channel C gain control 3 10 CHANNEL C 3 10 CLIP SIGNAL ATTENUATION dB 6 3 10 1 0 INF CHANNEL B 6 QB Q1004 Channel B gain control Power, Clip and Signal indicators POWER 20 0 ATTENUATION dB 3 10 1 20 CHANNEL A 6 6 3 10 INF ATTENUATION dB 600W (Channel A) gain control 8 6 3 20 Power switch SEE PAGE 6 FOR OPERATION DETAILS • FRONT PANELS 6 10 Channel A gain control Gain control CLIP SIGNAL 3 10 POWER 1 20 0 INF ATTENUATION dB 600W Power, Clip and Signal indicators 600W (Channel D) gain control Power switch A500 SEE PAGE 3 FOR INPUT WIRING • SEE PAGES 4 & 5 FOR OUTPUT WIRING • REAR PANEL CHANNEL B O U T P U T I N P U T Channel B Output connector CONNECTOR WIRING INPUT 2 HOT 3 COLD 1 GND OUTPUT 1+HOT 1-COLD MINIMUM LOAD 4 OHMS FUSE MADE IN ENGLAND BY CHEVIN RESEARCH LTD OTLEY LS21 3LP LINEAR AUDIO POWER AMPLIFIER MODEL: A500 Channel B Input connector A700v CHANNEL A FUSE RATING 110-120V = 16A 220-240V = 7A PLEASE SEE MANUAL DANGER OF ELECTRIC SHOCK WHEN COVERS REMOVED SN: Fuse Mains input CONNECTOR WIRING INPUT 2 HOT 3 COLD 1 GND OUTPUT 1+HOT 1-COLD MINIMUM LOAD 4 OHMS I N P U T Channel A Input connector O U T P U T Channel A Output connector SEE PAGE 3 FOR INPUT WIRING • SEE PAGES 4 & 5 FOR OUTPUT WIRING • REAR PANEL O U T P U T Output connector I N P U T FUSE CONNECTOR WIRING INPUT 2 HOT 3 COLD 1 GND OUTPUT 1+HOT 1-COLD MINIMUM LOAD 4 OHMS FUSE RATING 110-120V = 16A 220-240V = 7A PLEASE SEE MANUAL Input connector Q1004 • QB1000/600 DANGER OF ELECTRIC SHOCK WHEN COVERS REMOVED SN: Fuse MADE IN ENGLAND BY CHEVIN RESEARCH LTD OTLEY LS21 3LP LINEAR AUDIO POWER AMPLIFIER MODEL: A700v Mains input SEE PAGE 3 FOR INPUT WIRING • SEE PAGES 4 & 5 FOR OUTPUT WIRING • REAR PANELS CHANNEL C+D INPUT D INPUT C CHANNEL A+B MADE IN ENGLAND BY CHEVIN RESEARCH LTD OTLEY LS21 3LP INPUT B INPUT A FUSE RATING 220-240V = 40A Q1004 PLEASE SEE MANUAL CONNECTOR WIRING 2 HOT 3 COLD 1 GND OUTPUTS OUTPUTS CONNECTOR WIRING 2 HOT 3 COLD 1 GND LOAD 4 OHMS MINIMUM CONNECTOR WIRING Vari speed cooling fan Channel C & D input XLR sockets CH.A:1+ HOT 1- COLD CH.B:2+ HOT 2- COLD DANGER OF ELECTRIC SHOCK WHEN COVERS REMOVED SN Channel C & D output Speakon sockets (1 per ch) Fuse Channel A & B output Speakon sockets (1 per ch) CHANNEL C+D QB1000/600 INPUT D INPUT C Channel A & B input XLR sockets Vari speed cooling fan Channel A & B input XLR sockets Vari speed cooling fan CHANNEL A+B MADE IN ENGLAND BY CHEVIN RESEARCH LTD OTLEY LS21 3LP INPUT B INPUT A FUSE RATING 220-240V = 20A 110-120V = 40A PLEASE SEE MANUAL CONNECTOR WIRING 2 HOT 3 COLD 1 GND OUTPUT C/D CONNECTOR WIRING 2 HOT 3 COLD 1 GND OUTPUT C/D LOAD 4 OHMS MINIMUM OUTPUT A/B CONNECTOR WIRING CH.D:2+ HOT 2- COLD (600W) CH.C:1+ HOT 1- COLD (1000W) LINEAR AUDIO POWER AMPLIFIER MODEL: QB1000/600 Vari speed cooling fan OUTPUTS CONNECTOR WIRING CH.D:1+ HOT 1- COLD CH.C:2+ HOT 2- COLD LINEAR AUDIO POWER AMPLIFIER MODEL: QB1004 OUTPUTS Channel C & D input XLR sockets CONNECTOR WIRING CH.D:2+ HOT 2- COLD (600W) CH.C:1+ HOT 1- COLD (1000W) CH.A:2+ HOT 2- COLD (600W) CH.B:1+ HOT 1- COLD (1000W) CH.A:2+ HOT 2- COLD (600W) CH.B:1+ HOT 1- COLD (1000W) DANGER OF ELECTRIC SHOCK WHEN COVERS REMOVED SN Channel C & D dual output Speakon sockets OUTPUT A/B Fuse Channel A & B dual output Speakon sockets 9 A750 • A1000 • A1004 • A1500 • A2000 • A3000 6 6 3 10 1 20 POWER CLIP SIGNAL 0 INF 3 10 1 20 0 INF ATTENUATION dB Axxxx LINEAR AMPLIFIER SEE PAGE 6 • FRONT PANEL ATTENUATION dB CHANNEL A POWER CHANNEL B Power, Clip and Signal indicators Channel A gain control Channel B gain control A4000 • A5003 Power switch SEE PAGE 6 FOR OPERATION DETAILS • FRONT PANEL POWER 6 6 10 3 1 20 INF POWER CLIP SIGNAL 0 0 ATTENUATION dB CHANNEL A Channel A gain control 1 INF ATTENUATION dB Axxxx LINEAR AMPLIFIER 3 10 20 CHANNEL B Power, Clip and Signal indicators A5000 • A6000 Channel B gain control Power switch SEE PAGE 6 FOR OPERATION DETAILS • FRONT PANEL Model shown is A6000.
