POWERPLAY PRO HA4600

POWERPLAY PRO with the appropriate monitor-, subgroup or single outputs from the mixing console. Please note that the AUX inputs are set up for stereo. To play in a stereo signal you will need a stereo jack. If you use a mono jack it is advisable to activate the MONO switch, so as to get a signal distribution over both halves of the headphone.

3.3Using the DIRECT IN input

The DIRECT IN socket is situated on the left side of the front panel. It is often necessary e.g. to replay a piece of music to the musicians in the studio via a DAT recorder. This can be done simply and easily using the DIRECT IN socket. Use of this input automatically blocks the signal set up over the MAIN IN socket.

3.4Using the MONO function

For some monitor applications, especially in live operation, a stereo program can often sound irritating. This negative effect becomes particularly clear if the two channels show a large channel separation, i.e. they have different information content, linked with significantly different impressions of sound volume. The MONO switch permits mono operation, that is, the linked operation of the left and right channels without having to use a “Y” adaptor or a special cable.

3.5Using the MUTE function

If the MONO switch is in the depressed position, the unit works in mono operation. Pressing one of the two MUTE switches mutes the corresponding input signal (left or right input) and the non-muted signal can then be heard over BOTH (left and right) headphone outputs. This routing option means that you can set up two different programs via the left and right inputs and make just the one or the other audible as desired.

The Mute function is particularly useful if playback is to be combined with the simultaneous recording of a vocal track. Whereas before it was necessary for a singer to hold one headphone pad away from his/her ear during a music recording in order to hear his own voice better, with the HA4600 the playback can now be switched to stereo mode and the unused channel switched to mute. The previous normal—and uncomfortable—practice of moving one headphone pad away from the ear is now a thing of the past.

3.6Connecting several headphones

All four stereo amplifiers have three headphone output sockets on both the front and rear panels. This means that several headphones can be connected via each amplifier at the same time, provided that the minimum connection impedance of the amplifier does not drop below 100 Ohm. Since the amplifiers are resistant to temporary short circuits, no damage will occur if the level drops below this impedance, but it can lead to a loss of quality in the form of distortion and reduced performance.
