Weighted
90dB typical, 86dB Min Unweighted
**Total Distortion
Less than 0.08% at limit reference level and
and Noise
1kHz; less than 0.3% at -34dB
Frequency Response
20Hz to 12kHz +1, -2dB, measured 12dB below limit
level with Delay Multiply at Xl; bandpass is re-
duced to 6kHz, 3kHz, and 1 .5kHz with Delay Multiply
at X2, X4, and X8 respectively.
Delay capacity
128ms at full bandpass - standard; 256ms at full
bandpass with optional add-on Delay Memory Module
Delay Multiply
Extends delays by X2, X4, or X8; (2048ms with add-
on Memory option)
Delay Taps
Two, individually selectable in 60 steps with
digital display of each setting
Delay Adjustment
Continuous and noiseless adjustment from 100% to
50% of selected delay time; max. sweep range up
to 1024ms
vco Modulation
Depth adjustable from 0 to 100% of Delay Adjust-
ment range; Frequency adjustable from 0.1 to 20Hz
Delay Accuracy
0.01% long term in Cal mode plus .12ms delay offset
Inputs
Main and auxiliary inputs: balanced, 40k input
impedance, 20dB gain switch allows matching of
levels from -18dB to +18dB at limiting, XLR-3
type connectors.
Master output
Transformer isolated, balanced, 90 ohms max., ad-
justable to 18dBm max., XLR-3 type connectors
supplemental outputs
Delay A, Delay B, and Input Mix, 100 ohms max,
single ended,
~~~
phone jack connectors; A and B
Outputs adjustable from +8to +18dBm
Input Mixer
5 faders for Main Input, Auxiliary Input, Delay A
and B recirculation, and Master; 5 level LED Head-
room Indicator verifies proper mix level
Recirculated Delay
Individual control for recirculated Delays A and
Rolloff
B from 15kHz to 800Hz
output Mixer
5 faders for Dry Input, Aux Input, Delay A, Delay
B and Master Out with overload indicator
*Defined as the ratio of the 1kHz output level at reference limit level to
the output level with the input shorted across 600 ohms.
Unweighted noise
is measured over the bandwidth of 20Hz to 20kHz. Weighted noise is measured
according to the ANSI "A" curve.
**Input sensitivity set
so
that an lBdBm input corresponds to
"0"
LED just
going out (this is "limit level"). Output sensitivity set to produce +lBdBm
with 600 ohm load under these conditions.
