    Rolls HRD342 reviews

    HRD324 Digital Room/Speaker Delay is rated 2.0 out of 5 by 2.
    Rated 1 out of 5 by from Poor Audio Quality This box does create a delay in the signal and worked to that degree just fine. �BUT, when listening to the output with this box in place and comparing it to when this box wasn't in place, the quality of the output signal is degraded significantly. �I have to return this item based on the poor output audio quality.

    Rated 3 out of 5 by from Works but noisy The delay works as it should bit the output signal has a high noise level. Supplying a higher than normal input signal helped improve the signal to noise. In this application (speach) that made the unit acceptable, I don't think I would want to try it on music though.
