SAFETY INFORMATION Safety Information Safety of Mains Operated Equipment This equipment has been designed to meet the safety regulations currently advised in the country of purchase and it conforms to the safety regulations specified by use of the CE Mark. SAFE T Y IN FORMAT I ON Warning : There are no user serviceable parts inside the equipment. If you should ever need to look inside the unit, always disconnect the mains supply before removing the equipment covers.
SAFETY INFORMATION Power Cable and Connection An IEC power connector is supplied with the HY-03 which has a moulded plug attached – this is a legal requirement. If no moulded plug has been supplied with your HY-03, please contact your supplier, because an IEC connector is always supplied from the Sonifex factory. If for any reason, you need to use the HY-03 with a different power cable, you should use the following wiring guidelines Connection Earth (E) Neutral (N) Live (L) Table B : Power Connections.
SAFETY INFORMATION Ordering the Correct Mains Lead When ordering a TBU from Sonifex, it is helpful if you can specify your required operating voltage and mains lead. After the product code add: UK, for 230V, UK 3 pin to IEC lead EC, for 230V, European Schuko 2 pin to IEC lead SAFE T Y INFORMAT I ON US, for 115V, 3 pin to IEC lead vi AU for 230V, Australasian 3 pin to IEC lead Table C : Mains Lead Table. E.g. order HY-03S UK for a UK IEC lead to be supplied.
SAFETY INFORMATION WEEE & RoHS Directives - Sonifex Statement The Waste Electrical and Electronic Equipment (WEEE) Directive was agreed on 13 February 2003, along with the related Directive 2002/95/EC on Restrictions of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS).
REPORTING FAULTS Reporting Faults REP ORT I N G FAU LTS Although this Sonifex product is manufactured to the highest standards, it is possible that minor faults may appear in the equipment over its normal lifetime.

INTRODUCTION 1 1 Introduction The HY-03 is a high quality analogue telephone hybrid, which is suitable for most general telephony applications and is often used in radio and TV stations, bingo halls and dealing floors. The analogue HY-03 telephone hybrid is the replacement for the HY-02, which for many years has set the standard as an excellent value, high quality telephone hybrid. • Fully automatic – adapts to varying line conditions and has automatic signal limiting.
1 INTRODUCTION What is a Telephone Hybrid? Telephone hybrids (or telephone balance units, TBUs) provide the interface between professional audio equipment and the public telephone network. They provide protection for your equipment and the public telephone lines, allowing for varying line signals and line conditions.

1 INTRODUCTION The telephone line socket is connected to the telephone network using the cable provided (either RJ11 to RJ11, or RJ11 to BT plug). A simple telephone handset can be used to take and make calls when plugged into the equipment handset connector. An adapter is provided if the handset is fitted with a BT plug as standard. INTROD U C T I ON A remote switch may be connected at the Remotes socket in order to control the line connect switch from say, the telco channel of a mixing desk.
INTRODUCTION 1 Using the HY-03 Receiving a Call With the equipment connected as in Figure 1-4 calls may be received and detected by the ringer in the telephone handset. To receive the call, lift the handset and establish contact with the caller. The call may be diverted to the telephone hybrid by pressing either the front panel mounted line connect switch or by means of the remote divert switch (if connected). Note : The remote lamp tally mimics the front panel line connect switch lamp, i.e.
1 INTRODUCTION Q: What type of remote lamp will the HY-03 drive? A: The remote lamp type should be 15V at 40mA max. When connecting any loads the current should be limited to this value using a series resistor. For example a 390 ohm resistor would limit the current to 38mA. INTROD U C T I ON To connect/disconnect the unit pins 1 and 2 should be connected together via a contact closure or equivalent.

Line Connect Switch This is the front panel button used to connect calls to, and disconnect calls from, the telephone line. The switch will illuminate to indicate the call has been connected.
2 CO N F I G U R AT I ON & CO NT ROLS Adjusting the Microphone Gain Level The Mic Level Preset Pot controls the level of the input signal when the input signal mode is set to Mic. The input signal level in Line mode is factory set and is not affected by this control. The Mic Input will accept 200 ohm microphone level signals and is balanced/ floating with a maximum gain of 74dB. Use a jeweller’s screwdriver to adjust the gain between 74dB and 40dB.
CONFIGURATION & CONTROLS 2 design exchange systems are designed to have a K-break signal lasting 50ms). British Telecommunications plc may, in some situations where no end of call signal is available, be able to provide one at the request of a UK customer. Line Polarity Reversal Disconnect Enable - SW2 and JP5 When SW2 is enabled (ON) (and for serial number HY-03 units after HY000323 when JP5 is on), the HY-03 will automatically disconnect from the telephone line by detecting the line polarity reversal.

CONFIGURATION & CONTROLS 2 Note : The noise gate threshold is factory set for optimum performance, so will not normally need adjustment. Important Note : There are a number of other controls which are factory set, or should only be used when testing/aligning the product. These are RV2, RV5, RV6, RV7 and RV7 jumpers JP2 and JP3. Please note that these controls should not be adjusted in normal Res Set operation and could damage the performance of your product if altered.
