GENERAL INFORMATION

GENERAL INFORMATION 2.1

The Model 8895-AMP-8 & 8895-AMP-16 Entertainment Amplifiers are four-channel audio amplifiers designed to provide entertainment audio to patients within a hyperbaric chamber environment. The amplifier is one part of a complete system to provide entertainment audio. Amron has all the components available to build a complete system, including cables. Patients wear a pneumatic headset (the same type as used by the airline industry) to provide audio entertainment for passengers. This configuration was selected so that the patients could use the headset while receiving oxygen treatment and still safely have audio entertainment. No electrical energy is present at the headset. Volume level is adjustable by each patient, and each patient has channel selection control. Up to four audio selections can be provided. The patient headset is driven by a patient entertainment module which converts the electrical signal to a sound pressure wave to drive the pneumatic headset. The audio transducer is isolated from the pneumatic headset via a diaphragm. The electrical signal to the patient entertainment module is a low voltage/low wattage signal, typically one watt with a maximum voltage of 12 VDC. A volume control is provided as part of the headset tubing, allowing each patient to adjust their listening level. Each patient entertainment module has channel selection capabilities. A push-button switch allows the patient to step through up to four different selections of audio. Again, in keeping with the safety issues of a chamber environment, the electrical switching is done with low voltage current, limited logic level signals. Up to eight patient entertainment modules can be driven by the 8895-AMP-8 and sixteen can be driven by the 8895-AMP-16. A 110/220 volt selector switch is located on the rear of both the Model 8895-AMP-8 & 8895-AMP-16. Select the desired voltage by turning the sector switch with a small slotted screwdriver.

INSTALLATION & OPERATION

OPERATION 6.1

Turn power on and confirm power is on by observing the power on indicator. Make sure all sources of audio are on and operating properly. On initial set up, set all volume controls on the source devices to minimum and all front panel volume controls to mid scale. Use one of the headsets within the chamber, making sure the volume control valve on the sound tubing is full “ON”. Slowly advance source “A” while listening to the headset within the chamber. Cycle the source selector switch to locate the presence of audio and confirm the operation of the system. Set the volume level for source “A” for a comfortable level on the headset in the chamber. Repeat this procedure for source “B”, being sure to first advance the channel selector one step. After setting channel “B”, repeat this procedure for channels “C” & “D”. If you are not going to have four sources of audio material, you can leave a channel open (nothing connected) or you can put the same material on multiple channels using a “Y” cable available from any retailer selling audio equipment (female jack to two male jacks). Once the volume levels are set for the four channels, note the position of the volume controls on the source equipment. The volume controls on the front panel adjust the range of audio levels which the amplifier will accommodate. If you have a source of material which has a low output you can increase the sensitivity of that channel without affecting the other channels. The master volume (MV) controls the output of the amplifier and adjusts the volume level to all patient entertainment modules. Once a proper level is achieved no further adjustment should be necessary.

INSTALLATION & OPERATION

9

INSTALLATION 6.2

If you have purchased a complete system, begin by installing all components. The patient entertainment module should be installed in a convenient location for the patient to reach while seated in a normal position. Patient will need to be able to reach the yellow push button switch in order to change channels. The outer junction box should be installed before the inner junction box. This makes it easier to feed the wires through the chamber penetrator. After both junction boxes are installed, connect the electrical feed-thru wires in the inside junction box. Next you will want to run the patient entertainment module cables to the inside junction box, routing the cable through one of the appropriate strain reliefs. Connect the wires from the patient entertainment module as shown on the System Interconnect Diagram, DWG NO. 8895-SYS-D101. There are four wires from each module, two are clear and two are blue in color. Use an ohmmeter to identify the clear wire with the switch in the line and connect as shown. Next identify the blue wire on the side opposite the speaker from the switch and connect as shown. Connect the remaining wires, clear and blue as shown. Route and install the cable between the amplifier and the outer junction box. Connect the amplifier to the audio source components and check out the system confirming the presence of audio and proper operation of the channel selector.

THEORY OF OPERATION

THEORY OF OPERATION 7.1

The 8895-AMP-8 & 8895-AMP-16 are built in two configurations, an 8-patient and a 16-patient version. There are eight output audio amplifiers in the -8 and sixteen in the -16, each driving one patient entertainment module. Each of the amplifier’s inputs can be remotely controlled to select one of four input sources of audio. The remote source selection is done by a push button on the patient entertainment module. The entertainment module contains an audio transducer which produces an audio sound pressure wave to drive a pneumatic headset similar to those used by the airline industry for in-flight audio entertainment. The entertainment module has a diaphragm to separate the transducer from the sound tube. This prevents the possibility of the back flow of oxygen into the transducer when the headset is being used in an oxygen enriched area such as an oxygen treatment hood. The amplifier unit has four stereo inputs, each having a left and right audio input. This allows the system to be connected to a stereo source. The stereo information is mixed using a center taped transformer. The transformer also provides isolation from the source equipment. The output of the transformer is fed to a potentiometer to control the signal level. The output of the volume control is fed to an operational amplifier to buffer the signal. There are four separate circuits, one for each of the four input sources of audio. This input section has two output jacks, J6 & J8, which feeds the audio output section of the amplifier card. The audio output amplifier is fed by one of the four input audio sources. The patient controls the source by activating the channel selector button. The contact closure is de-bounced and steps a ring counter. The ring counter output is buffered and decoded from binary by a series of “AND” gates. The output of the “AND” gates drives a four pole analog switch which routes one of the four input audio sources of the input of the final audio output amplifier. The selection of audio sources is “A”, “B”, “C” and “D”; and then repeats beginning with “A”. The audio amplifier I.C. is a stereo unit. Each side is used for separate channels. Each unit has a separate volume control which is voltage controlled. All amplifiers are controlled from a common volume control. The output of each amplifier’s current is limited by resistors and capacity; and is coupled to eliminate any D.C. voltage which might appear on the output. All of these circuits are powered from a common power supply. The supply uses fuses mounted on the P.C. card. Fuses are ½ amps and each side of the line is fused. The AC power switch interrupts the AC line before the power transformer. The power transformer is a medical grade transformer providing excellent isolation from the line and low leakage current. A full wave rectifier, filter capacitors (C23, C35 & C34), and two 3-terminal fixed voltage regulators are used. The first regulator is 15 Volts and the second is 5 Volts. On the 8895-AMP-16 a second amplifier card is used. The second card uses the same power transformer as the first card. Also the input audio section of the first card is bused to the second card. The input volume controls on the second card are not used, and left off the card along with the AC power switch. All other circuits of the second remain functional and operate in the same manner as the first card.

MAINTENANCE

PERIODIC TESTS & CHECKS 8.1

The patient entertainment module pressure integrity should be checked annually. This can be done without disturbing module. Remove the headset and pressurize the tubing line to the entertainment module with 10 PSI of air. The module should hold this pressure without loss for a period of 60 seconds. If the unit does not hold pressure, check the o-ring on the back side of the audio transducer. If a leak is detected, do not use this patient entertainment module/headset in an oxygen enriched environment. No other specific routine maintenance is required. No preventative maintenance is required. A functional check of all circuits may be desirable; however, a problem report by the end user will identify any problems.
