6 Introduction to the GP1 Overview The GP1 Location Broadcast Mixer is available in three frame sizes: 6, 8 and 12 Input Modules. The GP1 also has an Output & Meter Master Module,and a Monitor Module. The Output meters are VU or PPM. The GP1 is lightweight, for portability, whilst also being rugged. The power consumption is low to ensure a long usable life for the internal batteries (typically 8-10 hrs from Ni-Cd cells, and hrs from alkaline cells - both figures for the 12 Input version). Although the GP1 is primarily designed for remote use with on-board battery power, the mixer may also be rack mounted (8 Input variant only), or furniture mounted. It may be mains powered via the PPS110 power supply. 2 Introduction

7 Precautions and Safety Instructions General Precautions Avoid subjecting the mixer to conditions of excessive heat or cold, or installing it in positions where it is likely to be subject to vibration, dust or moisture. Do not use any liquids to clean the fascia of the unit: a soft dry brush is ideal. Use only water or ethyl alcohol to clean the trim and legend strips. Other solvents may cause damage to paint or plastic parts. Avoid using the mixer close to strong sources of electromagnetic radiation (e.g. video monitors, high-power electric cabling): this may cause degradation of the audio quality due to induced voltages in connecting leads and chassis. For the same reason, always site the mixer power supply away from the mixer. Caution! Power supply & cables Warning! Warning! In all cases, refer servicing to qualified personnel. Always use a power supply and power cables specified for the mixer: the use of alternative supplies may cause damage and voids the warranty; the extension of power cables may result in malfunction of the mixer. Before switching on the power supply, check that the mains voltage selectors are correctly set to the voltage for your area, and that the fuses are of the correct type and rating. This is marked on the case of the power supply. Do not replace the fuses with any other type, as this could become a safety hazard and will void the warranty. Always switch the power supplies off before connecting or disconnecting the mixers power cables, removing or installing modules, and servicing. In the event of an electrical storm, or large mains voltage fluctuations, immediately switch off the PSU and isolate from the mains. The power supply is connected to the mixer via the 4-way socket, marked DC Power, on the rear panel. Always ensure that you use a suitable power supply for the mixer. The GP1 may use a PPS110 power supply (see details of the power connection below), or a suitable external source. The mixer is powered from an external power supply when the POWER switch on the rear panel is set to EXT. PPS110 Power Supply A PPS110 power supply is supplied with all variants of the GP1. The power supply is capable of operating over a wide range of mains input voltages by means of a comprehensive set of selectable voltage settings. It is important to ensure that the correct voltage setting has been selected for the level of local AC mains input voltage supply, for safe, uninterrupted-operation of the units. Warning! DO NOT CHANGE THE AC MAINS VOLTAGE SETTING WITHOUT FIRST DISCONNECTING THE MAINS PLUG FROM THE MAINS SOCKET. The power supply is provided with an IEC-type mains connector, coupled with a voltage selector with integral AC mains fuse holder. Confirm that the arrow moulded into the connector unit aligns with the voltage setting that is correct for your area. Voltage selection should be as follows: 100Volt setting for AC Mains Input Volts AC 120Volt setting for AC Mains Input Volts AC 220Volt setting for AC Mains Input Volts AC Introduction

8 240Volt setting for AC Mains Input Volts AC To change the selected voltage, prise off the fuse holder square top with a screwdriver-type tool, using the square blade tip in the slot. Pull the fuse carrier assembly clear of the body, rotate the fuse carrier body until the required input voltage lines up with the arrow, and then push the fuse carrier back into the connector body. Warning! Replacing Mains Fuse DO NOT USE DC MAINS INPUT VOLTAGES Switch the units on/off mains switch to the off position, remove the mains lead plug from the mains supply socket. Check the fuse and replace if necessary: also check that the voltage selector is correct for the mains supply level before switching the unit on again. The correct fuse ratings are as follows: 220/240 VAC fuse rating T1.0A/250V 100/120 VAC fuse rating T2.0A/250V Warning! TO AVOID THE RISK OF FIRE REPLACE ONLY WITH THE CORRECT VALUE AND TYPE OF FUSE AS INDICATED ON THE UNIT. In the event of repeated failure of the mains fuse, consult the dealer from whom the unit was purchased.

Rack Mounting The PPS110 can be provided with an optional 19-inch rack-mounting kit: it occupies 2U of rack space. Batteries The Location Mixer may also be powered by its own internal batteries: 12 or 16 D type cells are required: the 6 and 8-input variants use 12 cells, the 12-input variant uses 16 cells. These may be primary cells or rechargeable cells; all cells must be of 4 Introduction

9 the same type, do not mix types. The access panel for inserting and removing the cells is on the underside of the mixer. Warning! DO NOT try to recharge dry (primary cells: they may explode, and the wiring will melt if this is attempted Rechargeable cells may be recharged from the power supply. To do this set the CHARGE switch on the power supply to on. It is not advisable to charge the cells and use the mixer at the same time: performance specifications may not be achieved under adverse conditions. The mixer is powered from the internal cells when the POWER switch on the rear panel is set to INT. Signal Levels It is important to supply the correct input levels to the mixer, otherwise signal-tonoise ratio or distortion performance may be degraded, and in extreme cases damage to the internal circuitry may result. Likewise, on all balanced inputs, avoid sources with large common mode DC, AC or RF voltages, as these will reduce the available signal range on the inputs. Note that 0dBu = 0.775V RMS. The microphone inputs are designed for use with balanced, low impedance (150 or 200) microphones. Caution! DO NOT use unbalanced microphones or battery powered condenser microphones without isolating the phantom power - degraded performance or damage to the microphone may result. Introduction 5
