Audio Amplifier for MRI Stereo Systems • Part No. PTA22BT
- This audio amplifier is compatible with all the Scan Sound MRI patient stereo sound system kits
- There are 3 sets of Line-In RCA Jacks on rear of audio amplifier labeled CD, Aux1 and Aux2 and a front-panel swich can select the music source directly from music sources such as a CD player, computer, FM radio or MP3 player
- This amplifier can also pair with nearly all types of Bluetooth audio devices, such as a cell phones, MP3 players and tablets
- There are separate microphone and music volume controls allowing for independent level settings of the music and microphone audio going to the patient headphones
- The amplifier output connects with the Patient Acoustic Interface in the MRI scan room, enabling the patients to hear the music in special acoustic headphones that they wear inside of the MRI scanner
- This mixer / audio amplifier can be used as a direct substitute for the older Scan Sound PT600A amplifiers that came with their earlier MRI stereo kits
- A microphone jack on the amplifier will accept a 1/4-inch mono microphone plug
- A slide switch on the rear can be set to PAGER mode so that the music automatically fades as the technologist speaks into the microphone so the patients can clearly hear the technologist's voice above the level of the music
Replacement Audio Amplifier for MRI Patient Stereo Systems • Part No. PTA22BT
This audio amplifier has a line-in with 2 RCA audio jacks to accept low-level audio from music sources, such as an AM/FM stereo unit or the earphone jack of an MP3 player. The amplifier also has Bluetooth built-in, so it can be used to receive audio from MP3 players that are Bluetooth enabled, such as an Apple iPhone, iPad or iPod.
The audio amplifier has speaker terminals on the rear which will connect to left and right channel audio cables that go to the Patient Acoustic Interface in the MRI scan room. There is a microphone input on the amplifier. When the microphone is activated, the amplifier automatically ducks down the music source coming from the line-in input or Bluetooth music sources, making this amplifier ideal for use with an MRI sound system.
It is easily possible to substitute this newer amplifier in place of the original PT600A amplifier that we typically used with our older MRI patient stereo sound systems.
The PTA22BT model has a volume knob on the front which will easily set the music level that goes out to the patient acoustic interface. A headphone jack is present to allow users to test the amplifier and hear the sound that normally goes out to the patient. When plugging headphones into that jack, it defeats the audio going out of the amplifier's rear speaker terminals, so the headphone must be removed after testing, so that the sound will resume and the music will be heard in the patient headphones.
Customers who have a Scan Sound MRI stereo that are purchasing this amplifier as a replacement for the older PT600A can request a diagram that shows how to connect the new amplifier in place of the old one.
