5. IP1 In-ear Phones

The IP1 (see fig. 9) have been specifically designed for generating very high sound pressure levels. A frequency range from 20Hz to 20,000Hz ensures high-end sound quality throughout the audible spectrum. The supplied earmolds attenuate unwanted ambient sound and guarantee optimum, secure fit. On request, the in-ear phones are also available with earmolds individually fitted to your ears. Please contact your local AKG representative.

5.1.Standard Accessories

1 pair of EM1 earmolds (see fig. 9a)
1 cable sheath (see fig. 9b) for tightening the cable behind your neck

5.2. Optional Accessories

Individually fitted earmolds (refer to section 5).

6. Frequencies

Each SST1 stationary stereo transmitter and SPR1 stereo bodypack receiver have up to 16 carrier frequencies stored in memory. You can select any one of these frequencies on the transmitter by calling up the appropriate menu and on the receiver by setting the CH rotary switch (6e). The Frequency Tables on the transmitter (fig. 5) and on the receiver (fig. 8) indicate the frequencies stored in your IVM1.

If, depending on local frequency allocation plans, your VM1 stores less than 16 frequencies all remaining storage locations contain the highest frequency.

6.1. Frequency Sets

Each Frequency Set has its own designation (figs. 5 and 8). Check that each receiver uses the same Frequency Set as the transmitter it is assigned to. This is the only way to make sure the individual frequencies on the receiver and transmitter are identical.

6.2. Ordering Transmitters and Receivers

When ordering replacement transmitters or receivers, please state the Frequency Set designation (figs. 5 and 8) and the serial number of the original transmitter or receiver. This allows us to guarantee that the Frequency Sets on the replacements are identical to those on your original equipment.

6.3. Selecting Frequencies on the SST1

As long as the transmitter is connected to AC power, you can select or change the frequency in the "RF Channel" menu (refer to section 7.5.10).

6.4. Selecting Frequencies on the SPR1

You can select a different frequency anytime using the CH rotary switch (6e).

7. Setting Up

7.1. SPR1 Receiver

7.1.1. Inserting/Replacing the Batteries

Prior to switching the power ON, screw the receiving antenna (7a) into the antenna socket (7b).

Set the VOLUME control (7c) between 1 and 4 in order to protect your ears from unexpected excessive sound levels.

Refer to fig. 6f:

1. Unlock the battery compartment cover by turning the locking screw 90^ CCW with a coin.
2. Push the battery compartment cover outward in the direction of the arrow and open the cover.
3. Insert the supplied 1.5-V batteries into the battery compartment, aligning them with the polarity marks. Incorrectly aligned batteries will not power the receiver.
4. Close the battery compartment cover and push it inward against the direction of the arrow until it clicks into place.
5. Lock the battery compartment cover by turning the locking screw 90^ CW.

7.1.2. Powering Up

1. Switch the receiver ON with the POWER I/O switch (6b) and use the supplied screwdriver to set the CH rotary switch (6e) to the desired frequency.
2. The indicator LEDs (6a), (6c), and (6d) indicate the operating status of the receiver. Refer to the table below:
3. Connect the cable of the IP1 in-ear phones to the output jack

POWER LED (6c)	MUTE LED (6a)	Peak LED (6d)
lighting green:· Unit is ready to operate; battery charge is sufficient.	lighting red:· Carrier frequencies on SPR1 and SST1 are not identical.· Reception is disturbed (excessive separation from transmitter, shadow effects, etc. Refer to sections 8 and 9.)	not lighting:· Optimum system levels.
blinking green:· Batteries will be dead within approx. 60 to 90 minutes.		blinking green:· 3 dB below clipping.
not lighting:· Batteries are dead or unit is switched OFF.	· SST1 not connected to power or in RF OFF mode.		lighting red:· System overloaded.
	not lighting:· System is ready to operate. (Or the unit is switched OFF.)

(7d).

1. Insert each in-ear phone into one EM1 earmold, making sure the cable will be pointing the same way as the "finger" on each earmold (refer to fig. 9d, 1 to 3).
2. Insert the earmolds into your ears referring to fig. 9d, 4 to 8.

Important: Always use both in-ear phones because this is the

only way you can hear your personal monitor mix perfectly. If you use only one in-ear phone, the effect of IVA processing will be lost.

1. Slide the cable sheath (9b) up to the point that the cable will rest securely against your neck (see fig. 9d, 9 to 11).
2. Set the BALANCE L/R control to its center position. If necessary, you can change the balance between the left and right channels at any time during the soundcheck.

7.2. SST1 Transmitter

1. Connect the supplied AC adapter (fig. 4) to the transmitter and plug the power cord into a convenient AC outlet. The AC adapter will operate on any line voltage between 100 VAC and 240 VAC with no switching or modifications.

The display will indicate the installed software version. After a few seconds, the display will change to the last active menu (refer to section 7.5).

1. To feed a mono signal to the SST1, connect your source to the LEFT/MONO INPUT XLR socket (2b). Switch the transmitter to mono mode in the "Stereo/Mono" menu (refer to section 7.5.2).

To feed a stereo signal to the SST1, connect the left channel of your source to the LEFT/MONO INPUT XLR socket (2b) and the right channel to the INPUT RIGHT XLR socket (2c). Switch the transmitter to stereo mode in the "Stereo/Mono" menu (refer to section 7.5.2).

1. Use the IN LEVEL control (1c) to set the input level.
   The IN LEVEL LEDs (1c) illuminate green at levels between -50 dBV and -8 dBV, and red when the integrated soft knee limiter engages.
2. Use the VOLUME control (1b) to set the output level at the PHONES jack (1a).
3. Connect either the supplied BNC antenna (fig. 3) or an optional remote antenna (fig. 12) to the ANTENNA socket.

7.3. Battery Life

Be sure to use new, fresh AA size 1.5-V batteries only We recommend IEC LR61 alkaline batteries from Duracell, Panasonic, or Varta.

Guaranteed battery life, depending on the sell-by date, is 6 to 10 hours for dry batteries, 3 hours for good quality, fully charged NiCd or 6 hours for NiMH rechargeable batteries.

7.4. IVA - Individual Virtual Acoustics

One drawback of listening over headphones is the psychoacoustic phenomenon that you will hear the sound inside your head. The IVA (Individual Virtual Acoustics) binaural audio processing technique simulates a concert stage environment. It simulates a combination of conventional monitors and sidefills as they would typically be placed on a stage.

The IVM1 provides eight ear matching functions, "Ear1" through "Ear8" from which you can select the one that sounds best to you. When selecting the ear matching function, listen for good stereo balance and a smooth, natural sound. The other menus described in section 7.5 allow you to adjust the IVM1 to your individual preferences as to room size, sound, reverberation, panorama, etc.

7.4.1. How IVA Works

Fig. A: Natural hearing: Sound waves arriving at one ear

differ from those at the other. Amplitude and phase differences create a sense of spatial hearing.

Fig. B: Listening through headphones: Amplitude and

phase differences are eliminated. Sound sources are localized inside the head rather than in the room.

Fig. C; Listening through headphones using IVM1 and IVA: The ear matching function changes the audio signals

at the ears to resemble fig. A. This restores natural binaural, spatial hearing.

9. Antenna Placement

Reflections off metal parts, walls, ceiling, etc. or the shadow effects of musicians and other people may weaken or cancel the transmitter signal.

For best results, place your antenna as follows:

1. Place the SST1 transmitter near the performance area. Make sure, though, that the transmitter will never get any closer to the SPR1 receiver than 10 ft (3 m). Optimum separation is 16 ft. (5 m).
2. If you use a remote antenna, place it near the performance area and as high overhead as possible. Again, maintain 10 to 16 ft. (3 to 5 m) of separation.
3. There should always be a direct line of sight between the transmitter and receiver.
4. Place the transmitter with the screw-on antenna or the remote antenna at least 5 ft. (1.5 m) away from any big metal objects, walls, scaffolding, ceilings, etc.
5. Place the SST1 transmitter at least 10 ft. (3 m) away from wireless microphone receivers (e.g., SR 300) in order to prevent any crosstalk from the in-ear monitor system into wireless microphone channels.

10. Before the Soundcheck

Before switching the sound system on, check the following:

1. Make sure that the transmitter and receiver operate on the same frequency. (Refer to section 6.1.)
2. Be sure to use fully charged dry or rechargeable batteries. If in doubt, insert new batteries (Refer to section 7.1.)
3. Check the performance area for "dead spots", i.e., places where the field strength seems to drop and reception deteriorates. If you find any dead spots, try to eliminate them by repositioning the receiver. (Refer to section 8.)
4. Check that the transmitter input signal level has been set for optimum modulation with the IN LEVEL control.

11. Protection against Hearing Damage

Do not use any other headphones than the IP1 miniature in-ear phones specifically designed by AKG for the IVM1. This is the only way to ensure that the two-stage protection system will function properly. This system comprises a limiter integrated in the transmitter and a clipping diode at the phones output on the SPR1 receiver.

If, due to malfunction, the volume shoud rise to a level that may damage your hearing, the built-in limiter will instantly reduce the level automatically.

Using any in-ear phones other than those recommended by AKG may defeat this protective function! AKG therefore declines any liability whatsoever.

Warning: Listening at excessive volume levels over an extended period of time may cause severe damage to your hearing.

12. Cleaning

To clean the surfaces of the transmitter, receiver, and earmolds, use a soft cloth moistened with methylated spirits or alcohol.

13. Accessories

Rack Mount Unit accepting one SST1 and AC power adapter. Provides an alternative antenna socket on the front panel.

13.2.RMU 12 (Fig.11)

Rack Mount Unit accepting two SST1 transmitters and their AC power adapters. Provides alternative antenna sockets on the front panel.

13.3. SRA1 (Fig. 12)

Remote antenna for optimum antenna placement independent of the transmitter location. Particularly recommended for use with rack mounted SST1 transmitters because it is often difficult to place a rack where it would ensure optimum UHF propagation.

13.4. Other Recommended Products

Logitek PR10 Input Extender (Fig. 14)

In a professional multichannel system, the PR10 Input Extender allows the same signal to be fed to two VMM systems simultaneously.

One VM1 functions as a backup system that can be cut in immediately if the other system should fail.

Conex AS 101 Audio Switcher & AS 401 Remote Control (Fig. 14)

The AS 101 allows the monitor engineer to listen to the monitor mix for each artist separately.

All mixes can be selected at the push of a button either on the AS 101 itself or on the AS 401 remote control.

Suhner (Fig. 13)

Suhner makes antenna cables of extremely high quality. Thanks to their extremely low attenuation, these allow longer cable runs than standard types with almost zero signal loss.

www.hubersuhner.com

Directional Antenna (Fig. 15)

For applications where the mixing position is more than 200 ft. or 230 ft. away from the stage, we recommend to use directional antennas, for instance, the Hirschmann model shown in fig. 15. These antennas will increase the range of the transmitter without the need for extremely long antenna cables. Ask your AKG dealer for more information.
