When the switch is depressed power is applied, when released, the power is switched off. ! The volume control bis a rotary type. Turn this fully anticlockwise to its minimum setting (0). ! Switch on the power amplifier (and control unit if used). ! Switch on the QUAD twenty fourP via the ON/OFF switch bThe mains indicator will light and the unit is operational. Warming Up Valve equipment needs time to reach operating temperature. Allow at least five minutes for the QUAD twenty fourP to 'warm up' before use. Warming up should always be done with the system volume control at zero. If you are using a valved power amp the warming up period should be extended to at least fifteen minutes. If you play loud music while the system is cold the valves will be starved of both voltage and current. The resulting distortion is unpleasant and potentially damaging to your amplifier and speakers. Operation Normal Operation:After it has warmed up fully, the system is ready for use. Remember to turn the main system volume control to minimum when changing records, and especially when cleaning your stylus. Adjusting Sensitivity: Adjustments to sensitivity may be carried out with the unit operational only if the system volume control is first set to minimum. Turn up the volume control only after adjustment. Switching Off: When not in use the unit should be switched off. Using the QUAD twenty fourP as a Control Unit If there is sufficient gain in the power amplifier, the QUAD twenty fourP can be used as a control unit in a basic audiophile system comprising a turntable, power amplifier and loudspeakers. To do this, connect the VARIABLE output of the QUAD twenty fourP directly to the power amplifier signal inputs. If the power amplifier has an input level control this should be advanced to maximum as the volume control on the QUAD twenty four P will now function as the system volume control. Volume Control On/Off Switch OPERATION INFORMATION TO THE USER Good Practice Switch off all equipment in the system before connecting or disconnecting signal leads. This will prevent unpleasant and loud noises coming from the loudspeakers and avoid the risk of damage to equipment. Please be aware that high sound pressure levels can cause permanent damage to your hearing and severe annoyance to neighbours. Guarantee and Product Registration Your Quad equipment is guaranteed against any defect in material and workmanship for one year from the date of purchase (proof of purchase required). We ask that you complete and return the enclosed Warranty Registration Form. Within the guarantee period, Quad will undertake replacement of defective parts free of charge provided that the failure was not caused by misuse, accident or negligence. Your statutory rights within the territory in which you purchased the equipment are not affected by this guarantee. Quad carries out a regular review of its products and reserves the right to adjust the specifications and performance from time to time. There are no user replaceable or serviceable parts inside this unit. Unauthorised attempts to service or modify this product will invalidate the warranty. Service Arrangements Equipment for servicing should be returned to the supplying dealer, or to the appointed service agents for your area. The addresses of Service Agents for the UK, USA and Canada are listed at the rear of this manual. If you are abroad and there is no suitable dealer in your area, please contact the distributor for the country in which it was purchased or Quad Electroacoustics Ltd. Equipment returned for service should use the original packing. Please enclose a brief note with your name and address and the reason for returning the unit. Care and Cleaning The equipment should be switched off and allowed to fully cool down before being cleaned with a barely damp cloth. Avoid using solvents and abrasives as they will damage the paint finish. Dry fully before re use. Running In Most high fidelity equipment works better after it has been run in for some time. In the case of valve equipment the period of running in is much more important. Components that go into valve equipment work at voltages and temperatures far higher than their solid state counterparts and when new they should spend an extended period at those working temperatures to bed in properly. This is especially the case with power amplifier output valves and output transformers. We recommend an initial running in period of at least four and preferably twelve hours before you first use the equipment. The patience and care that you devote in these initial stages will be amply rewarded by many years of outstanding performance from your QUAD valve equipment. 7 2 QUAD twenty four P Owner s Manual QUADtwenty four P Owner s Manual
