Как настроить микрофон shure pgx4

Хочу поделится пятилетним опытом работы с радиосистемами Shure pgx4 (база) и pg58/sm58/beta58 (сам микрофон). У меня в наличие 12 шт. Микрофон лидер в своей категории, но есть несколько подвохов:
— Если у тебя много микрофонов, лучше их пометить (базу и микрофон). Я покупал микрофоны не разом, а частично. У меня есть два белых, два желтых и.т.д Как то я в спешке собрал комплект и на мероприятие база не видела микрофон, оказалось что я взял микрофон такого же цвета, но от другой базы у которой как оказалось другая частота (не номер настраиваемого канала) 800-820 MHz. Это был пизд.. Совет: смотрите на частоту она может быть разной на базах. Частота на базах пишется сзади справа, а у микрофонов где батарейки, там есть наклейка,типа R1 800-820 MHz )))

— Треск и хрип во время работы на улице, при питание от генератора. Проблема в блоке питания. С шурами в комплекте раньше шли большие блоки, а сейчас маленькие. Вот с большими постоянно такая беда, им не хватает напряжения и при резкой нагрузки (если в микрофон крикнуть) сигнал начинает искажаться. Совет: При работе с генератором пользуйтесь маленьким блоком питания, а лучше используйте стабилизатор напряжения )))

— Настроить отдну частоту на нескольких базах. Нажать кнопку #channel# для выбора наиболее чистого канала. Если на другой базе искать тотже канал нажимая просто поиск, то тот же какнал он может не найти. Поэтому на другой базе зажимаем кнопку #channel#,выбираем сначала первую цифру, потом еще жмем пока не замигает вторая цифра, и выбираем вторую цифру. Для чего это нужно спросите вы, как то раз мне нужно было сделать следующие: представьте торговый центр с двумя этажами, и тремя корпусами. Нужно было подключиться к их местной аппаратуре вещания, для того чтобы ведущий ходил по торговому центру и везде ловил микрофон. Я набрал кучу XLR поставил несколько баз по всему ТЦ,подключил их в пульт, выставил одинаково EQ и гейн, и все прошло ок, если одна база пропадала ловили три, если три пропадали ловила одна, были правда при этом мини помехи, но результат был на 95% положительный )))

— Проблема с гнездом питания. Почти на всех базах перепаивал гнездо куда втыкается штекер от блока питания, дело в центральном штырьке, он отходит от самого контакта.Разбирается база быстро, одна капля олова решает эту проблему )))

— Можно уменьшить чувствительность головы на 10db,нужно открутить саму голову (не решетку) все верхнюю часть с названием головы shure sm58,там будет переключатель 0 -10 db )))

2 AA batteries
PS24 Power Supply
User guide

Lavalier, Headworn, and Instrument systems include:

PGX1 bodypack transmitter
Microphone (choice of WL93, WL185, PG30 or Beta 98H/C™)

PGX4 Receiver Features

Front Panel

Indicates strength of incoming audio signal: green for normal, amber for strong and red for clipping.

Displays group and channel setting. See “Single System Setup” for details.

Changes group and channel setting. See “Single System Setup” for details.

Indicates system ready and receiving an RF signal from the transmitter.

⑤ Infrared (IR) port

Sends IR signal to transmitter for sync.

Press to synchronize transmitter with receiver group and channel settings.

Back Panel

⑦ AC adapter jack

⑧ Adapter cord tie-off

⑨ XLR microphone output jack

⑩ 6.35 mm (1/4”) instrument level output jack (unbalanced).

Transmitter Controls and Connectors

① Indicator LED Displays battery level, mute, and IR transmission status (see table).

② Power / Mute Switch Press to mute or unmute. Press and hold to power on or off.

③ Infrared (IR) port Receives infrared beam to synchronize frequencies. When using multiple systems, only one transmitter IR port should be exposed at a time.

④ 4-Pin Microphone Input Jack.

⑤ Audio Gain Adjustment.

Transmitter Indicator LED

Green	Ready
Flashing green	Controls Locked
Amber	Mute On
Flashing red	IR transmission in process
Glowing red	Battery power low
Pulsing Red on startup	Batteries dead (transmitter cannot be turned on until batteries are changed)
Pulsing Red after synchronization	Transmitter and receive incompatible; contact your Shure reseller

Changing Batteries

Expected life for an Alkaline battery is approximately 8 hours.
When the transmitter light glows red, the batteries should be changed immediately, as shown.

Wearing the Bodypack Transmitter

Clip the transmitter to a belt or slide a guitar strap through the transmitter clip as shown.

For best results, slide the transmitter until the belt is pressed against the base of the clip.

Adjusting Gain

Three gain settings are available on the PGX1. Choose the appropriate setting for your instrument.

mic: Microphone (higher amplification)
0: Guitar with passive pickups (medium amplification)
–10: Guitar with active pickups (lower amplification)

If the receiver LED indicates the input volume is overloading the receiver, try switching the gain to a lower setting.

Access the gain adjustment switch by unscrewing the head of the microphone.

Two gain settings are available on the PGX2. Use the tip of a pen or a small screwdriver to move the switch.

0dB: For quiet to normal vocal performance.
–10dB: Use only if audio is distorted due to high voal levels.

Single System Setup

Use the scan feature on the receiver to find a clear channel.

a LED screen displays current channel

b press channel button to scan for a clear channel

c system scans for the channel with the least interference

Synchronize the transmitter to the receiver by aligning the infrared (IR) ports and pressing the sync button. Make sure the IR ports are closely aligned.

After a successful sync, the transmitter LED momentarily flashes red and the receiver ready light illuminates.

Multiple System Setup

Use the following steps to ensure the best performance when installing multiple wireless systems at the same location.

Note: Turn on any other digital equipment that could cause interference during the performance so it will be detected during the frequency scans in the following steps.

Make sure the group number is the same for all receivers (see Manual Group Selection).

Perform a scan using the first receiver.

Turn on the first transmitter and sync it to the receiver.

Repeat for each system.

Important: After syncing each transmitter, leave it on so that scans from the other receivers will not select that channel.
Be sure only one transmitter IR port is exposed when synchronizing each system.

Manual Channel and Group Selection (receiver only)

Using the receiver to scan for a channel is the best way to find the best frequency for your system. However, for multiple system setup, you may need to manually set the group number.

Press and hold the channel button.
Hold the button until the channel or group display begins flashing.
Release and press the button again to advance the setting. At the desired channel or group number, wait for the flashing to stop. This activates the new setting.
Transfer the new frequency setting to the transmitter using the automatic sync function.

Locking and Unlocking Controls

Locking the system controls prevents accidental muting or channel adjustment during performances.

To lock the controls: With the transmitter off, hold the power button down until the green LED flashes (

To unlock the controls: With the transmitter on, hold the power button down until the green LED flashes (

To lock the channel: Hold the channel button until the numbers flash (

To unlock the channel: Hold the channel button until the numbers flash (

Troubleshooting

Issue	Indicator Status	Solution
No sound or faint sound	Transmitter power light on, receiver LEDs on	Perform automatic transmitter setup Verify all sound system connections
	Receiver LED off	Make sure AC adapter is securly plugged into electrical outlet Make sure AC electrical outlet works and is supplying proper voltage
	Transmitter power light glowing or flashing red	Replace transmitter batteries If indicator continues flashing red after batteries are replaced, the transmitter and receiver may belong to incompatible frequency bands. Contact your Shure reseller for assistance.
	Transmitter power light off	Turn on transmitter Make sure the +/- indicators on batteries match the transmitter terminals Insert fresh batteries
Distortion or unwanted noise bursts	N/A	Remove nearby sources of RF interferance (CD players, computers, digital effects, in-ear monitor systems, etc.) ‣ Change receiver and transmitter to a different frequency ‣ Reduce transmitter gain ‣ Replace transmitter batteries ‣ If using multiple systems, change the frequency of one of the active systems
Distortion increases gradually	Transmitter power light glowing or flashing red	Replace transmitter batteries
Sound level different from cabled guitar or microphone or when using different guitars	Adjust transmitter gain as necessary
Cannot turn transmitter on	Transmitter light flashing red	Replace transmitter batteries
